Profiled tube — a kind of steel pipe. This category of products includes a wide range of products long products. She is in high demand among construction, manufacturing, agricultural and machine-building enterprises. What is the difference between these products and how to choose from the assortment of shaped tubes the best? Such questions probably asked yourself buyers. To help understand the intricacies of the purchase will help the experts and the major producers of long products.

What is a profiled tube

Shaped tube called a kind of long hollow metal products. The profile of the pipe is characterized by several kinds of shapes, but different from the round. Thus, there are variants:

  • Square;
  • Rectangular;
  • Oval;
  • Oval;
  • Arch.

Distribution made up of pipes with square and rectangular section that explains the correct form of the section.

Assortment of profile pipes

Speaking about the range (the term comes from the concept of variety), mean list of varieties of products of this type offered in the market. Thus, the assortment of shaped tubes includes metal products, General characteristics of which — core design and not round cross-section. With these products, there are differences:

  • Sectional shape;
  • Material;
  • The technology of obtaining;
  • Size profile
  • Wall thickness.

Profile

This parameter is fundamental, as the assortment of products with different sectional shape (profile) separately.

Types in the form:

  • Rectangular pipe. This type of high-quality rolled metal has 4 ribs, making it a high tensile strength and deflection. No less important is the light weight, which is achieved by the hollow design. In addition to the benefits of the product is called convenient storage and ease of transportation.
  • Square tube. This product combines the abovementioned advantages of rectangular pipe, while it is characterized by compact dimensions. Without the assortment of profile square tubes will not do in cases of severely limited space.
  • Oval, arch. Such variants are often used in case of special requirement from the object.Polygonal and sections. Sold and profile tube with a polygonal slice or more recesses, however, they are produced according to individual orders.

Technology for

All kinds of profile pipes, regardless of the shape of the profile are made on similar technology.

Assortment of profile pipes GOST

All of them are 3.

  1. Cold-Rolled. According to cold drawn technology, the starting material for the production of profile pipes are conventional round pipes of suitable diameter. The process is reduced to running round the pipes on special machines. As a result, the product is given the desired form.
  2. Hot-deformed. The technology of manufacturing cold-rolled similar to the fact that the starting material is round tube. However, there are differences — before rolling, the steel is heated to a high temperature. Because of this, the metal does not occur high internal stress and is given the finished products with special performance characteristics.
  3. Welded. Manufacturing welded by the method involves the use of non-round pipes and pieces of sheet metal. Them runs in to impart the desired profile, and then join the edges by welding.

Requirements of GOST to the assortment of profile pipes

Pipe with a profile other than round, is considered one of the most important segments of the total long products. They are widely used in construction and other important objects, therefore, must be manufactured subject to stringent requirements. According to GOST 30245-2003 assortment of shaped tubes is characterized as the product roll-formed closed welded profile in the shape of a rectangle or square.

Assortment of pipes according to GOST

However, the GOST — is not the only regulatory document. For each type of profile pipes additional requirements.

Materials

Another distinctive feature of the assortment of shaped tubes called material. Commonly used steel. It can be:

  • Low;
  • Carbon;
  • Stainless steel.

Each pipe is assigned a systematic name. It will certainly indicate the grade of steel, each relating to one group or another. This characteristic greatly influences the strength, flexibility, durability and other indicators of the finished product (including the cost). Less common are pipes made of other materials, such as aluminium.

Square pipe: varieties

The dimensions of the profile tubes with square profile vary depending on production technology. Assortment shaped tube cold deformation includes products with a cross section 10-120 mm. wall Thicknesscan reach 1-8 mm.

Assortment of profile pipes square

Products of hot deformation is produced with a cross section of 30-140 mm, the thickness can be 4-14 mm electric-Welded profile pipes have a thickness of 1-5 mm, and the size of the cross section of 10-100 mm.

Rectangular cross section

Pipe having a rectangular cross-section, and different sizes of sides and wall thickness.

Assortment of tubes profile steel

The Smallest considered tube 15*10 mm, and the oversize 230*100 mm wall Thickness varies from 1 to 14 mm. the larger the section, the greater must be the thickness of the wall. This allows the pipes to withstand high loads and serve for many years.

Advantages

Assortment of profile pipes steel a few distinct advantages that enable their use in the fields of construction and industry.

  • Among all the bar sections of the profile pipes have the lowest metal content, which significantly reduces the weight and cost of the structure.
  • These products are easy bending, cutting and welding, which reduces the speed of installation products.
  • Consideration of sanitary standards in the production makes them easy to maintain.
  • Made from steel, the tubes have a full fire.

The Buyer selects the product on the basis of the main requirements of the project, the scope and features of operation. In other words, there is no perfect solution for the two projects, completely different direction, cost and features of the application.

Profile pipe: assortment

Having Considered the characteristics and differences of profile pipes to make a conclusion: this kind of metal is diverse and is extremely useful in many areas of industry. However, strong and durable will be those products that were manufactured based on specific requirements and standards. For this reason before purchase of metal should be familiar with the supporting documents.
