Thin-walled profile pipe
Thin-walled profile pipe

A profile pipe is a metal pipe with a cross section that differs from the standard round one (it can also differ from the round and outer section). Most of the profile pipes have a rectangular or square section. A profile pipe mainly has the functions of a structural element. As a rule, the product is used as a metal bar, but due to the presence of four stiffeners and low mass without a significant change in bending strength, it is widely used in construction. In fact, the main load when bending the bar falls on the extreme sections, i.e. In this case, the core of a metal bar is not subjected to severe deformations, as a result of which it allows the use of a profile pipe with equal success. Weight gain allows you to save on metal and use more complex designs. In the manufacture of a profile pipe, any metal can be used, but steel is usually preferred. The square Kharkov pipe is made from different grades of steel. It can be of such sizes, ranging from 20x20 to 200x160 mm. The most commonly used products are 40x20 and 80x80 mm, because the rectangular and square section of the profile pipes has four stiffeners and a low mass, which does not affect the bending strength index. In addition to strength characteristics, it is worth considering the cost-effectiveness of this type of pipe (it is about 25% percent compared to ordinary pipes), as well as the convenience of laying a rectangular pipe on flat surfaces. Together with a profile pipe it is very convenient to use a wire for welding, which in this case facilitates installation. Automatic and semi-automatic arc welding of profile pipes gives us the opportunity to obtain complex structures that can withstand high loads. In addition to the main construction and civil engineering purposes, a profile pipe is often used in repair work, to create strong frames (for example, under a metal door), in advertising (for the construction of durable structures that withstand static loads and the climate of different regions - in this case, small the weight of the profile pipe is a decisive factor) in the automotive industry and in the manufacture of furniture. A rectangular profile pipe is produced under the influence of heat treatment or without its influence. Like ordinary pipes, a profile pipe is produced by the method of hot deformation, cold deformation (with higher structural qualities), and using an electric-welded technique or an electric-welded cold-deformed one (as a rule, in this case the product is somewhat more expensive, but stronger). State standards 380 and 1050-88 regulate the production of profile pipes and describe the requirements for the metal used. A square profile pipe is usually made in two ways: -the metal sheet is cut into billets, then create box sections that are fixed with a seam; -the finished round pipes are compressed from all sides by special rolls, after which a square pipe is obtained. According to GOST, there is the following pipe marking: ST2, ST3, 8KP, 10, 20 and low-alloy pipes of profile 09g2s and 17gs. The pipe profile 09g2s is used for showcases or racks. Indisputable advantages of this type of pipe are the minimum number of seams and resistance to the adverse effects of weather conditions. Our metal base is ready to offer our customers profile pipes: profile pipe (square, rectangular), electric-welded pipe, steel profile steel pipe at very competitive prices. Profile pipe is a type of pipe with a cross section that differs from round. First of all, it is a square profile pipe and a rectangular pipe. The electric-welded profile pipe has the most common profile sizes - 40x100, 50x50, 40x80. For the production of a profile pipe, any metal can be used, but most often steel is chosen. Profile pipe prices, sales In recent years, more and more Russian construction companies are selling profile pipes, as well as erecting facilities where they use profile pipes. Profile pipe, the price of which can significantly reduce the cost of construction by saving metal, low weight and a small number of parts. Prof. steel profile pipe is also used for the manufacture of general goods. It is best to buy a profile pipe at a nominal price from the manufacturer. Profile pipe metal rolling Profile-welded pipe is used in combination with various wires for welding, which greatly facilitates their installation. Semi-automatic and automatic welding of profile pipes makes it possible to obtain very complex structures that can withstand very high loads.
