Steel pipe 40x40x2 weight of 1 meter running is a specific, tabular, theoretical, reference, conditional or linear weight of metal rolling. The names are used as synonyms and mean not the real weight obtained as a result of direct weighing on the scales, but theoretically calculated according to GOST. We can find data on the weight of 1 meter of a 40x40x2 mm steel pipe in the table from the reference book on the specific gravity of metal products or calculate it yourself. However, such calculations of the weight of 1 meter of pipe require some experience and knowledge of the mass recalculation formula. For example, the calculation of the mass of 1 mp square metal pipe, reduced to calculating the weight of the iron strip. Therefore, it is much more convenient to use the table. In principle, we need a table of specific, conditional, reference, calculated, theoretical or linear weight of the profile steel pipe, that part of it that refers to square pipes. Steel pipes of square section 40x40x2 mm are also profile pipes, but with equal width of both shelves. If the width of the shelf at the metal profile pipe is different, then such pipes are called steel rectangular. The more correct name for the iron square pipe indicated in the reference is a steel square closed profile. A metal square pipe 40x40x2 mm can be welded or seamless, but in practice, steel pipes with such a wall thickness are usually made as welded. And rightly considered thin-walled light pipes. A steel pipe of 40x40x2 mm is most often used for the production of metal structures for household, decorative, construction and industrial purposes. The profile metal pipe 40x40x2 mm welds well, is easy to cut, and bends conveniently if necessary. Therefore, bent and arched steel structures are made from a metal pipe 40x40x2 mm. The rental has light weight, with a relatively high rigidity, therefore metal constructions from a pipe 40x40x2 mm is called lightweight or light. For those tasks where an important condition for the manufacture of a welded metal structure is high strength or high resistance to corrosion, it is better to use pipes of the same cross section, but with a larger wall thickness. For water and gas pipelines, it is recommended to use steel metal pipes not welded, but seamless. In rare cases, a steel profile pipe 40x40x2 mm can be used for heating and water supply. The wall thickness of a square steel pipe 40x40x2 mm, in principle, allows using not only welded jointsbut also screw or rivets. But in general, a profile pipe 40x40x2 mm is not intended for this. Although it occasionally finds such application, for example: in the manufacture of fences from corrugated board and various frames, arbors, pavilions, awnings, peaks and entrance groups. The steel profile pipe 40x40x2 mm turned out to be a very convenient material for the manufacture of arched metal products, pergolas, decorative fences, fences, fences, front gardens for plant and flower stands, garden structures, gates, gratings, metal doors, swing and automatic gates, garden bridges, railings and stair railings. It is used both on the street and inside the house, in the country. The conditional, theoretical, tabular, calculated, specific gravity of 1 m p of a 40x40x2 pipe never exactly matches the mass obtained by weighing it on a scale and cannot serve as a “substitute” for scales. However, knowledge of the linear weight of 1 meter of pipe 40x40x2 mm allows you to quickly make theoretical, approximate estimates of the mass of the quantity available profile pipes. And also, it serves as an additional way of checking the correct operation of the scales. In order to calculate the weight of the available quantity of steel pipe 40x40x2 mm, you need to measure its length, usually use a tape measure for this. After which, the number of meters - the meter of pipe 40x40x2 mm is multiplied by the theoretical weight of 1 meter linear. The result is taken as the approximate or estimated weight of the pipe 40x40x2 mm. A very simple formula for calculating the weight of any pipes, both profile and round.

Profile pipe 80x80x3 is produced, as a rule, in accordance with GOST 30245-2003 (steel bent closed welded square steel profile for building structures) and TU-14-105-568-93 from carbon steel of ordinary quality st3, or from carbon quality steel with alloying additives, 09G2S. The pipe 80х80х3 is one of the most popular in the assortment of square pipes of large cross section. These products are widely used in the construction of residential buildings, modular buildings, industrial plants, hangars, sports complexes, garages and other buildings.
The powerful wall and four stiffeners of this profile square pipe withstand a rather large mechanical load. In addition, the 80x80 pipe has a small weight, which saves metal and allows the use of less powerful construction equipment during the installation of the profile pipe 80x80x3. Another advantage of a square pipe is the ease of laying it on flat surfaces. In this regard, a steel profile pipe is 20–25% more economical than a round one.
According to the production method, a profile pipe 80x80x3 can be hot-deformed, cold-deformed and electrowelded. If further it is supposed to operate the pipe under high pressure, the pipe passes hydraulic tests with a given pressure.
Major manufacturers in Russian Federation profile pipes 80x80x3 are such factories and metallurgical enterprises as OJSC EVRAZ, OJSC Severstal, LLC Severstal Pipe Profile Sheksna, OJSC MMZ, etc.

Rectangular pipe 80x40x2 6m St1ps
To give rectangular pipes certain physical and mechanical characteristics, various methods of their manufacture and subsequent heat treatment are used. Profiled pipes can be manufactured by cold rolling, hot rolling or pulling. As a result of heat treatment, the metal can increase hardness (hardening) or vice versa, become softer and more viscous (tempering). Additional manufacturing conditions must be specified by the consumer and recorded in a special contract. Quality standards are controlled by GOST 8645-68 with new additions and changes.
Billets for profiled pipes are seamless or welded round pipes; visual inspection of the quality is carried out before acceptance of products into the warehouse. Laboratory tests can be performed at the request of the wholesale buyer, each batch is tested, the batch weight is not more than 60 tons. To ensure the same mechanical characteristics, the batch of pipes should be made from one ladle of smelting, thus ensuring the uniformity of the metal in chemical composition. Physical properties the pipes comply with the international standard EN 10219: 2006, the cross section resistance moment W for rectangular pipes of size 80 × 60 × 2 is 6.38 cm3 in width (X axis) and 9.38 cm3 in height (Y axis) in height.
