Stainless Steel Materials

Seamless steel pipes are widely used.

1. General-purpose seamless steel tubes are rolled from ordinary carbon structural steel, low-alloy structural steel, or alloy structural steel, with high production volume. They are primarily used as pipelines for conveying fluids or structural components.

2. Offer three categories of supply based on different applications:

a. Supplied by chemical composition and mechanical properties

b. Supplied based on mechanical properties

c. Supplied for hydrostatic testing. Steel pipes supplied as types a and b, if used to bear liquid pressure, must undergo hydrostatic testing.

3. Seamless pipes for specialized uses include boiler pipes, chemical and power industry pipes, geological pipes, and oil pipes, among others.

Seamless steel tubes feature hollow cross-sections and are extensively used as pipelines for conveying fluids, such as oil, natural gas, coal gas, water, and certain solid materials. Compared to solid steel like round bars, they are lighter in weight while maintaining the same bending and torsional strength, making them an economical section steel.

Widely used in the manufacturing of structural components and mechanical parts, such as oil drill pipes, automotive drive shafts, bicycle frames, and steel scaffolding for construction, the use of steel pipes to produce annular parts enhances material utilization, simplifies manufacturing processes, saves materials and processing time, and has been extensively adopted.
