Carbon square pipe is a common construction material, mainly made of carbon or alloy steel. Its chemical composition includes elements such as carbon, silicon, manganese, sulfur and phosphorus, among which the carbon content accounts for a higher proportion of the total weight. The manufacturing process of carbon square pipe mainly includes hot rolling, cold drawing and cold drawing.

The characteristics of carbon square pipe include:

High strength: the strength and stiffness of carbon square pipe is higher than that of ordinary steel pipe, which is able to withstand greater pressure and moment.
Good corrosion resistance: the surface of carbon square pipe is treated to effectively resist the erosion of acids, alkalis and other chemicals, thus extending its service life.
Good easy processing: carbon square tube has regular shape and smooth surface, which is easy to cut, weld, stamping and other processing operations.
Light weight and low price: compared with pipes made of other materials, carbon square pipe is lighter in weight and cheaper in price, which is suitable for large-scale building construction and industrial production.
Carbon square pipe has a wide range of applications, such as construction, machinery, chemical industry, aviation, ship and automobile manufacturing. It can be used to manufacture lightweight frames, brackets, transmission pipes and so on.

Application:

It is a long piece of steel with a hollow cross-section and no seams around it. Steel pipe has a hollow cross-section and is used in large quantities as a pipeline for the transportation of fluids such as oil, natural gas, coal gas, water and certain solid materials. Compared with solid steel such as round steel, steel pipe is lighter in weight when the bending and torsion strength is the same, and it is a kind of economic cross-section steel, which is widely used in the manufacture of structural and mechanical parts, such as oil drilling rods, automobile driveshafts, bicycle frames, and steel scaffolding used in building construction. Steel pipe manufacturing ring-shaped parts, can improve material utilization, simplify the manufacturing process, save materials and processing time, such as rolling bearing rings, jack sets, etc., is widely used in steel pipe to manufacture. Steel pipe or a variety of conventional weapons indispensable materials, gun barrels, gun barrels, etc. to steel pipe to manufacture. Steel pipe according to the shape of the cross-sectional area of different can be divided into round pipe and shaped pipe. Since the circular area is the largest under the condition of equal perimeter, more fluid can be transported with circular pipe. In addition, the circular cross-section is more uniformly stressed when subjected to internal or external radial pressure, therefore, the vast majority of steel pipes are round pipes. However, the round tube also has certain limitations, such as under the conditions of plane bending, round tube is not as strong as the square, rectangular tube bending strength, some agricultural equipment skeleton, steel and wood furniture, etc. are commonly used square, rectangular tube. According to different uses also need to have other cross-sectional shape of the shaped steel pipe.
