Box section. Profile pipe: assortment. Classification and sizes of profile pipes. Square pipes: varieties

Profile pipe - variety steel pipes. This category of products includes a wide range of long products. It is in high demand among construction, manufacturing, agricultural and engineering enterprises. How do these products differ and how to choose the right product from the assortment of profile pipes? These are the kinds of questions that buyers have been asking themselves. Experts and large manufacturers of long products will help you understand the intricacies of the purchase.

What is a profile pipe

A profile pipe is a type of high-quality hollow metal. The profile of this pipe is characterized by several but different from round. Thus, the options are:

square;
rectangular;
oval;
flat oval;
arched.

Distribution reached pipes with a square and rectangular profile, which is explained correct form sections.

Assortment of profile pipes

Speaking of assortment (this term comes from the concept of variety), they mean a list of varieties of products of this type, which is offered on the goods market. So, the range of profile pipes includes metal products, general characteristic which is a hollow structure and not round section. However, these products also have differences:

section shape;
material of manufacture;
production technology;
profile size;
wall thickness.

Profile form

This parameter is considered fundamental, since the assortment of products with different sectional shapes (profiles) is indicated separately.

Form types:

Rectangular pipe. This type of rolled metal has 4 stiffening ribs, which makes it tear and deflection resistant. Equally important is the low weight, which is achieved due to the hollow structure. In addition to the benefits of products, it is worth mentioning convenient storage and ease of transportation.
Square pipe. Such a product combines the named advantages of a rectangular pipe, while it is characterized by compact dimensions. It is impossible to do without a range of profile square pipes in cases of severely limited space.
Oval, flat-oval, arched. These options are often used when special requirements object side. Polygonal and special profiles. Profile pipes with a polygonal cut or additional grooves are also sold, but they are made to order.

Receiving technologies

All types of profile pipes, regardless of the shape of the profile, are produced using similar technologies.

There are 3 in total.

Cold rolled. According to cold-rolled technology, ordinary round pipes are the starting material for the production of profile pipes. suitable diameter. The process boils down to rolling round pipe on special machines. As a result, the product is given desired shape.
Hot-formed. This manufacturing technology is similar to cold rolled in that a round pipe is used as the starting material. However, there are differences - before rolling the pipe is heated to a high temperature. Due to this, high internal stress does not arise in the metal and special characteristics are given to finished products. performance characteristics.
Welded. Production by the welded method involves the use of not a round pipe, but pieces sheet metal. They are run in to give the desired profile, and then the edges are connected by welding.

GOST requirements for the assortment of profile pipes

Pipes with a profile other than round are considered one of the most important segments of all rolled metal products. They are widely used in construction and other important objects, therefore, must be manufactured to meet stringent requirements. According to GOST 30245-2003, the assortment of shaped pipes is characterized as bent closed welded products with a profile in the form of a rectangle or square.

However, this GOST is far from the only regulatory document. For every kind profile pipe additional requirements apply.

Manufacturing materials

Another distinctive property of the assortment of profile pipes is the material. The most commonly used steel. She may be:

low-alloyed;
carbonaceous;
stainless.

Each is assigned a nomenclatural name. It certainly indicates the grade of steel, each of which belongs to a particular group. This characteristic greatly affects the strength, flexibility, durability and other indicators. finished product(including cost). Less common are pipes made of other materials, such as aluminum.

Square pipes: varieties

With a square profile, they differ depending on the production technology. The range of profile pipes of cold deformation includes products with a cross section of 10-120 mm. The wall thickness can reach 1-8 mm.

Hot deformation products are produced with a section of 30-140 mm, the thickness can be 4-14 mm. Electrowelded profile pipes have a thickness of 1-5 mm, and a section size of 10-100 mm.

Rectangular section

Pipes with a rectangular cross section differ in side sizes and wall thicknesses.

Pipes 15 * 10 mm are considered the smallest in size, and 230 * 100 mm are considered the largest. The wall thickness varies from 1 to 14 mm. How larger size section, the greater should be the wall thickness. This allows the pipes to withstand increased loads and serve for many years.

Advantages

The assortment of shaped steel pipes has several advantages that allow them to be used in the construction and industrial sectors:

Among all high-quality rolled metal, profile pipes have the lowest metal consumption, which significantly reduces weight and cost. finished construction.
Such products are easy to bend, cut and weld, which reduces the speed of installation of products.
Taking into account sanitary and hygienic standards in production makes them easy to maintain.
Made of steel, pipes have complete fire safety.

The buyer chooses a product based on the main requirements of the project being implemented, the scope and features of operation. In other words, there is no one ideal solution for two projects that are completely different in direction, cost and application features.

Having considered the characteristics and differences of profile pipes, we conclude: this type of rolled metal is diverse and is extremely useful in many areas of industry. However, those products that were manufactured in accordance with accepted requirements and standards will be durable and wear-resistant. For this reason, before buying rolled metal, you should familiarize yourself with the supporting documents.

All products are characterized by certain parameters. This also applies to water pipes. In addition, such a type of this product as profile pipes also has its own differences, its own classification, its own specifications, that is, dimensions, cross-sectional area, load capacity, material of manufacture, and so on.

Naturally, profile pipes are regulated by GOSTs during their production, so any deviation from their requirements is considered a marriage.

Some classification

A profile pipe is any other type of pipe other than a standard round pipe. The big advantage of such varieties is that the cross-sectional area, having equal dimensions with round products, will be larger.
Such pipes have excellent technical characteristics, especially when it comes to their strength.
They are used in many areas of life: heavy and light industry, agricultural engineering, furniture manufacturing and many other industries.
The classification of these materials can be built on the basis of many features, such as, for example, sizes, shapes, production methods, and so on. Let's look at this issue a little closer.
The following types are distinguished by form:

Square;
oval;
Flat-oval, that is, those in which two sides are straight, and the other two are made in the form of arcs, that is, rounded;
Rectangular.

General GOST for the manufacture of profile products has the designation 13663-86. Depending on the form, they are manufactured according to the following standards:

For square, GOST 8639-82 is applicable;
For rectangular, GOST 8645-68 is applicable;
For a flat-oval shape, GOST 8644-68 is applicable;
For oval, GOST 8642-68 is applicable.

Note! All such products are made of steel various kinds. I must say that each type of steel also has its own GOST.

If we talk about the production method, then the profile pipe will have two types:

Electrowelded;
Seamless.

Electrowelded can have several of its types:

thin-walled;
thick-walled;
Having a galvanized surface and not galvanized;
Straight line and many others.

Seamless has the following types:

Seamless;
Hot rolled;
Galvanized and non-galvanized.

Cold rolled and hot rolled steel

Here, too, a small caveat should be made. We will talk about those types of steel that are used for the manufacture of these products, but it’s worth understanding the difference between cold-rolled and hot-rolled products.
On the initial stage produce sheets by hot rolling. A large original sheet is cut into smaller pieces or into strips. Cold-rolled steel is first processed, that is, the pickling process takes place first. Only then does the cold rolling process start. For this reason, in the absolute majority, cold-rolled steel, or rather a sheet of it, cannot be thicker than 4-5 mm. The area, like other parameters, can take on a wide variety of values, but the thickness has an upper limit. However, the surface of such steel products is much better.
Such sheets have a constant thickness, whatever their area. In addition, they do not have scale. It must be said that the technical characteristics are much higher, since all steel materials undergo a hardening procedure before cold rolling. Accordingly, the load on products made from such material may be higher.

Seamless and electrowelded

If we have dealt with hot and cold rolling, now it remains only to figure out what seamless products are and what electrowelded products are.

Electrowelded products are obtained by molding and subsequent electric welding. They have seams that can be straight or spiral, hence the name - straight-seam and spiral-seam. These products can be made either from a sheet of low-alloy carbon type steel, or from a billet - strips.
A metal blank (sheet) is welded with its edges along one line. This is how straight-line products are obtained. The spiral variety is obtained by winding the steel tape in a spiral.
Profile pipes of such a plan can be used to create gas pipelines. In this case, the maximum load is 16 MPa.
All such types have their own GOST manufacturing.
All products can be thick-walled or thin-walled. In this matter, the production process has no effect.
Seamless products are obtained by rolling an ingot of steel. During this process, a hole is formed in the center, which is later calibrated in its shape and size.
I must say that seamless products can be manufactured in several ways at once, for example, forging or rolling.
As in the first case, a seamless pipe can be thin-walled or thick-walled. The most important advantage that all seamless products have is their incredible strength, which is achieved due to the absence of a seam - the very weak point. Basically, seamless products are used where it is necessary to constantly deal with high loads, both internal and external. The seamless pipe has gained great popularity in the oil industry, as well as in the field of transportation of highly aggressive media.

Some Specifications

The main ones include:

Profile form. There are rectangular, square and so on;
Dimensions, that is, height and width. Here it must be said that this indicator has its own GOST, however, manufacturers today produce profile pipes with any width and length;
Wall thickness. According to this parameter, it is divided into two types - thin-walled and thick-walled. This important parameter, since it is he who determines the scope. The wall thickness is regulated according to GOST, but there are exceptions;
Weight. It's not just the convenience of transportation and operation. Weight determines the quality of the product. Knowing the dimensions and mass, you can easily find out how thick its walls are, if this cannot be done by direct measurement.

What does the industry offer?

Today, the assortment offered by manufacturers is very wide. For example, consider products according to GOSTs 30245-94, 8645-68, 8639-82, that is, electric-welded pipes with different section shapes.
Assortment of square products (this includes both seamless and electric welded products):

External parameters from 10 to 10 to 120 to 120. At the same time, both thick-walled and thin-walled ones are produced, the wall thickness is from 1 to 8 mm - this is for cold-formed materials;
External parameters from 60 to 60 to 180 to 180. Wall thickness from 4 to 14 - this is for hot-rolled products;
External parameters from 10 to 10 to 100 to 100. At the same time, both thick-walled and thin-walled ones are produced, wall thickness from 1 to 5 - this is for electric-welded materials.

Here all values are in mm.
Rectangular pipe (this includes both seamless pipe and electric-welded pipe) has the following assortment:

Sizes from 10 by 15 mm with a thickness of 1 to 180 by 150 with a thickness of 12 mm;
Groups A and B. The first includes products made of steel grades St2 (4kp / ps), and the second - St.2 (4 kp / ps), as well as 08 kp and 10-35.

Range of steel products (both thin-walled and thick-walled, GOST 30245-2003):

For a square shape - from 4 by 4 cm with a thickness of 2 mm to 30 by 30 with a thickness of 14 mm;
Rectangular has such dimensions - from 5 by 2.5 cm to 40 by 20 cm, and the wall thickness is from 2 to 14 mm, respectively.

As you can see, there are plenty to choose from. And this is only part of the whole range of sizes, shapes and materials.

Wall thickness and other dimensions

In this article, we have mentioned many times such a concept as thin-walled or thick-walled. The whole point is this: for different sizes, the same thickness can be either small or large. Hence the names.
Naturally, thick-walled products will also cost more, since more material has been spent on their production.
The wall thickness can range from 1 to 14 mm.
I must say that depending on the type, the sizes also change:

Cold rolled - wall thickness from 1 to 8, dimensions from 1 to 12 cm;
Hot rolled - wall thickness from 4 to 14 mm, dimensions from 6 to 18 cm;
Electric welding - wall thickness from 1 to 5 mm, dimensions from 1 to 10 cm.

Most of the existing sizes are shown in the table below:

The length of the material also has some dependence on the method of production. This indicator ranges from one and a half meters to 12.5.
There is also a classification by length:

Measured length;
Unmeasured length;
Multiple measured.

For materials with a measured or multiple measured length, it is customary to add a margin of 5 mm. For this reason, the finished product at the exit may turn out to be 10 cm longer than the prescribed one.

In our time, the steel profile pipe has become widespread. supporting parts, make frames of stops for public transport, railings, benches and more. The most demanded field of application of steel corrugated pipes is reflected in the field of construction during the installation of metal structures and the construction of buildings.

A wide choice of types of professional pipes made of steel makes it possible to manufacture a suitable design for the necessary tasks.

The steel corrugated pipe has a cross section with 4 stiffeners. Despite the fact that such a product does not weigh much, it can withstand very large loads.

Their application

The use of shaped steel pipes is wide-ranging. Undoubtedly, the most basic area of use of profile pipe materials is construction. In modern building structures this type of pipe range is used everywhere.

Their use has the following advantages:

Metal is saved by almost a quarter when compared with the construction of a metal building using an I-beam.
Easy Installation and the small time spent on the construction of the frame and structure.
Such a metal structure is more resistant to the formation of corrosion manifestations when compared with other pipe rolling options. And cold-formed professional pipes successfully replace the two-tee beam, corners and channel.

Specifications

Consider the main technical characteristics of a profile steel pipe:

Profile view. Its main types are square, rectangular and oval. This criterion determines the division of the pipe profile in the general assortment.
geometric dimensions. For rectangular views, these are the width and height. As well as the length of each segment.
Wall thickness. Quite a significant detail, because it is it that determines the scope of further use.
Weight. An equally significant assessment that determines the quality level of goods. Through weight and geometric dimensions, you can find out the wall thickness. This becomes very useful in situations where the ability to access measurements is not available.

Describing steel professional pipes, it should be noted that their range is determined by GOST 8639-82. In this document, three main types of profile are distinguished:

Cold-formed.
Hot rolled.
Electrowelded.

The first two are seamless, and the third is produced from sheet material using welded technologies.

It should be noted that any characteristic of a pipe is dependent on a number of its other indicators. For these reasons, we can conclude that the presence of a table of the corresponding calculated values of GOST makes it easy to find out how high level quality from one manufacturer or another.

Assortment of these products

In addition to these parameters, classification can be made according to the following points:

Steel marking.
Absence/presence of finishing heat treatment.

The length parameters in this situation are determined by GOST 13663-86. This standard specifies that steel pipes different shapes are produced in standard measured segments, their length is from 1 to 12 meters.

The size of the section for professional pipes is determined by GOST 8642-68, respectively, these products were divided into 36 different types sizes with a cross section within 0.6 by 0.3 cm, and 0.9 by 3.2 cm.

By type of profile they are divided into:

Options in oval steel.
Products with a rectangular section.
With a square section.

Video

Depending on the scope of application, these pipes are classified into:

Profile pipes for furniture. The construction of them, as a rule, does not carry large loads.
Flat - oval types. Their other name is a profile for an arch. It differs in more complex manufacturing.
Options general purpose. They are made from hot-rolled 1.5 mm strip. Such products do not impose high requirements on the quality of the surface.
Construction. For their production, they take hot-rolled and low-alloy steel, which is characterized by increased strength indicators.

Square profile

Steel square profile pipe is widely used in the construction field.

It is the shape of the square in this situation that is the main advantage. It provides high stability and speed installation work.

These materials act as a reinforcing element in the construction of structures of supports and frames. They can be found not only in construction. No less often they are involved in the engineering industry.

Square pipes are divided into the following types:

seamless cold-formed or cold-rolled.
seamless hot deformation or hot rolled.
profile products obtained from sheet material and by means of welded technologies.

The assortment of such goods consists of products with a wall thickness of 0.1 to 1.4 cm, and a length of six to twelve meters. Masters call this type of product a guarantee of compliance with the financial costs of construction with their minimization.

Rectangular profile

A profile rectangular pipe is a type of pipe materials rectangular shape. This is a kind of subspecies of square options. It is also a hollow metal profile with various different sizes volume and wall thickness.

They are used in the assembly of structures and building elements on which the bearing role lies. They are taken for furniture frames, scaffolding for construction, children's areas and much more.

Features of the forms and low weight of products significantly reduce the weight main structure, but the resistance to the influence of high load effects in this situation increases. Often they are used as a protection channel for wiring a network of cables.

The main differences are determined by GOST 8645-78. According to these standards, there are such rectangular pipes:

with unmeasured length;
with measured length;
assortment with a short measured length.

Depending on the type, the length of seamless or welded materials varies from 11.5 to 12.5 meters:

Seamless professional pipes of random and measured length, made by hot-rolled method - from 4 to 12.5 m.
Seamless pipes random length, made in a cold-drawn way - from 1.5 to 12.5 m. And measured - from 4.5 to 11 meters.
Pipes of random length, made by the electric welding method - from 1.5 to 9 m, measured length - from 5 to 9 m.

When working with such profile products, allowances of 0.5 cm are made for each part. The maximum indicator for exceeding the length level as a whole is 10 cm.

Electrowelded profile

Steel electrowelded profile pipe is produced by different technological methods. The first of these is the formation of a profile from a flat billet. In this case, simple equipment is used, which is characterized by low energy costs. However, the resulting product has some disadvantages:

uneven distribution of stresses in the transverse arrangement of the section.
significant thinning of the profile blank in the corners.

In this case, advanced technologies allow changing the negative characteristics, which assume a uniform distribution of voltage at the initial stage. This forms a round billet with the desired volume.

Secondary processing in this case involves the formation of a section of the required dimensions and shape by means of the pressure of special rolls.

Steel galvanized profile

Galvanized profile pipe is a special type of rolled metal. The galvanized profile has increased anti-corrosion characteristics, which prolongs its service life.

Video

The advantageous difference between a galvanized product is:

The speed of installation work and their convenience.
Increased strength.
Breakage resistance.
Reducing the total weight of the structure without losing its strength capabilities.
Logistic convenience.

Their areas are very different, and the main ones among them are:

Construction of various scales.
Engineering.
Construction of prefabricated structures.

On the this moment this type of rolled metal can be found in billboards, fences, in commercial premises. And everywhere these steel pipes fully meet all regulatory requirements.

Manufacturing features

The production of shaped pipes is more complicated and more expensive than the production of round pipes.

Technological methods production of professional pipes is:

pressing round blanks produced at rolling mills. This option is expensive, therefore, the second type is more popular.
Welded connection of tape profiles.

The first method is remarkable in that it makes it possible to save strength characteristics steel pipes one hundred percent. The fact is that its connections are seamless. The sequence of production by this method is as follows:

First, a conventional hot-rolled billet is produced with round shape.
Through the press, it turns into an oval, takes the form of a square or rectangle.
Calibration of heated blanks is performed on the rollers of rolling equipment, so the products acquire the required dimensions.

Professional pipes, for the manufacture of which welding was used, are not very different from seamless counterparts, but at the same time they lose up to 5 percent of their strength. The release sequence in this case is as follows:

Sheet blanks steel is cut into strips.
After that, such strips are folded into a tape.
It is fed into the rollers of molding machines, which deform flat sheets into professional blanks.
The fastening seam is welded in special chambers, filled with an inert medium.

Video

The main advantage of a professional pipe is its small cost and great strength. It will not be difficult to buy this steel product. Managers of any company will provide all the information about their cost and characteristics.

Steel profile pipe is successfully used in the construction of commercial premises, warehouses, sports facilities, buildings for housing and production. These products are used as supports, columns, and various elements of various structures.

Their high strength makes them very popular for the creation of metal structures that stand out for their particular complexity. In the construction market, these products deservedly enjoy high popularity.

Entries

Profile pipes actively used in construction, mechanical engineering, furniture production and other areas, are presented on the modern market in a wide variety. In order to streamline this diversity and classify these products according to certain criteria, such a concept as assortment was introduced.

The very word "assortment", if we turn to dictionaries, comes from the word "variety" and means a list of individual types of products that are on the market. In relation to shaped pipes, the range means a set of types of these products manufactured manufacturing enterprises or available in the supplier's warehouse.

The range of pipes is presented in the form of a table or a simple list, in which individual types of products are listed in accordance with their names in accordance with GOST 13663 86 (profile square, profile rectangular pipes, etc.). Such a table or list should contain all available types of pipes, for each of which all names are signed and characteristics are given.

The assortment of pipes belonging to the profile category is very diverse. They are classified according to various parameters, but the main one is the profile cross section. So, pipes are distinguished:

with a rectangular profile;
square section;
flat oval;
oval;
with hollow ribs;
with a special type of profile.

The assortment is compiled separately for each type of pipe, which is regulated by the requirements of the relevant GOSTs.

The main parameters of the most common profile pipes - square and rectangular sections

Metal pipes belonging to a particular type of profile can also differ in a number of ways. The main of these parameters include:

the method by which pipes are produced (they are cold and hot rolled, welded);
materials used in production;
method of processing the ends of pipes;
main purpose.

The assortment of pipes, which is presented by a certain manufacturer, not only allows you to get acquainted with the range of its products, but also serves as an indicator of the level of its development. Consumers of such products and organizations selling them prefer to establish relationships with manufacturing enterprises, the range of pipes of which includes a wide range of products.

Assortment of profile pipes of rectangular section: GOST 8645-68

The clearest information about the range of steel rectangular pipes presented in the corresponding GOST, which is presented below.

Assortment of profile pipes of square section: GOST 8639-82

To get acquainted with the assortment, it is worth viewing the data from the corresponding GOST, which is presented below.

Criterias of choice

Of the entire assortment of modern profile pipe rolling, products with square and rectangular sections are the most common. Traditionally, they are made of metal, but now this material is increasingly being replaced by plastic.

The main field of application of profile pipe is the production of metal structures for various purposes, where these products are successfully replaced with solid steel bars. The big advantages of pipes compared to such bars are affordable cost and low weight.

When choosing profile pipes from the assortment for the manufacture of a metal structure, it is very important to correctly select their profile and cross-sectional dimensions. The main criterion that guides this choice is load bearing capacity pipes, both square and rectangular. It should also be taken into account that products with different cross-sectional dimensions can vary significantly in weight.

According to the production method, as already noted above, cold- and hot-formed steel profile pipes are distinguished in the assortment. In accordance with the requirements of GOST 13663 86, this also includes products manufactured using electric welding. These pipes, as well as cold-formed ones, can be covered with a layer of zinc, which prevents corrosion.

The cross-sectional dimensions of the profile pipe, the most popular in the construction market, are:

15x15;
20x20;
25x25;
30x30;
40x40;
60x60;
80x80;
100x60;
100x100.

Advantages of profile pipes

The profile category includes all pipes whose cross-sectional shape differs from round. The most widely used products from the entire assortment are with a square and rectangular profile, the dimensions of which correspond to 25, 60, 100, 40x80, 40x100, 50x50 mm.

Steel profile pipes, the dimensions of which exceed 100 mm, are used mainly as structural elements. Such products, which have four stiffeners, are distinguished by high strength characteristics and low specific gravity.

Products with a profile of 60 mm perfectly resist bending, due to which they are successfully used in construction and in the arrangement of various engineering communications.

Any profile pipes allow not only to create complex steel structures, but also significantly save on the cost of expensive metal.

Among the advantages of profile pipes made of steel, the following can be mentioned.

Their entire assortment is characterized by low metal consumption, which makes it possible to save up to 25% of metal even during the construction of one building object.
When using such elements, construction objects are erected with high efficiency.
The entire range of profile pipes produced by modern industry meets sanitary and hygienic requirements, the pipes are easy to maintain and disinfect.
Such products also comply with fire safety requirements.
Even the most complex structures when using these elements, they are mounted with maximum efficiency.

Applications

Steel pipes having different types profile, are actively used in many areas. Depending on the size of the profile, such products are used to solve the following tasks.

Pipes with a profile of 60x30 are characterized by low metal consumption, their use makes it possible to significantly save on the cost of metal during construction work.
For mounting metal structures various sizes and the degree of complexity, pipes with profile sizes of 15x15, 40x60, 60x60 and 100x100 are most actively used.
A number of advantages distinguish products with a profile size of 25x25. Such advantages include low weight, exceptional strength characteristics, tightness, ease of installation work.
