Seamless steel pipes have a wide range of applications.

1General-purpose seamless steel pipes are made from ordinary carbon structural steel, low-alloy structural steel, or alloy structural steel, with high production volume. They are primarily used as pipeline for fluid transportation or structural components.

2Supply is divided into three categories based on different applications:

aSupplied based on chemical composition and mechanical properties.

bSupplied according to mechanical properties;

cSupplied after hydrostatic testing.a、bSteel pipes of similar supplies, such as those used to withstand liquid pressure, must also undergo hydrostatic testing.

3Special-purpose seamless tubes include boiler tubes, chemical and power industry tubes, geological seamless steel pipes, and oil field seamless tubes, 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 with the same bending and torsional strength, making them an economical section steel.

Widely used in the production of structural and mechanical components, such as oil drill pipes, automotive drive shafts, bicycle frames, and steel scaffolding for construction, pipe rings manufactured from steel tubes can enhance material utilization, streamline production processes, and save on materials and processing time. Steel tubes are extensively used for this purpose.
