China Alloy Seamless Steel Tube Factory/ 4140 4142 Alloy Structure Pipe /Seamless steel tubes for structural purposes

Short Description:

Compared with solid steel such as round steel, seamless steel pipe for structure has the same bending and torsion strength and lighter weight. It is a kind of economical section steel, which is widely used in the manufacture of structural parts and mechanical parts such as oil drill pipe, automobile transmission shaft, bicycle frame, construction steel scaffold, etc. It only requires strength and rigidity, but not tightness of steel pipe.

Product Description

Low carbon steel pipe-carbon content is about less than 0.25%. Carbon steel pipes in oil products, oil and gas and public media with a design pressure lower than 10MPa-carbon content is between 0.25 and 0.60%, such as 35, 45 steel, etc.; high carbon steel pipes-carbon content is greater than Around 0.60%. This type of steel is generally not used in the manufacture of steel pipes. Carbon steel pipe-introduction Carbon steel pipe contains a certain amount of carbon, as well as silicon and manganese. Does not contain other alloying elements. Note that the silicon content generally does not exceed 0.40%. In order to ensure the chemical composition and mechanical properties of carbon steel pipes, we must control the content of impurities such as sulfur and phosphorus below 0.035%. Only in this way can high-quality carbon steel pipes be produced.
