タイトルまたは説明

Carbon steel seamless steel pipe is a kind of long steel with hollow section and no joints around. The steel pipe has a hollow cross-section and is widely used as a pipeline for conveying fluids, such as pipelines for conveying oil, natural gas, gas, water and some solid materials.

Compared with solid steel such as round steel, steel pipe has the same bending and torsional strength and is lighter in weight. It is a kind of economic cross-section steel, widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffolding used in construction.

The manufacture of ring parts with steel pipes can improve the utilization rate of materials, simplify the manufacturing process, save materials and processing time, such as rolling bearing rings, jack sleeves, etc., which have been widely used to manufacture steel pipes.

Steel pipe is an indispensable material for all kinds of conventional weapons, and the barrel and barrel are made of steel pipe. Steel pipes can be divided into round pipes and special-shaped pipes according to the different shapes of the cross-sectional area. Because the circular surface volume is the largest under the condition of equal circumference, more fluid can be transported with circular tubes. In addition, when the annular section is subjected to internal or external radial pressure, the force is more uniform, so the vast majority of steel pipes are round pipes.

The use of steel pipe to manufacture ring parts can improve the utilization rate of materials, simplify the manufacturing process, save materials and processing hours, such as rolling bearing rings, jack sleeves, etc., currently has been widely used to manufacture steel pipes.
