Seamless steel tubes have a wide range of applications. General-purpose seamless steel tubes are typically made from ordinary carbon structural steel, low-alloy structural steel, or alloy structural steel, with high production volume. They are primarily used as pipeline or structural components for conveying fluids.

.2. Offered in three categories based on different applications:

Supplied by chemical composition and mechanical properties.

b. Supplied by mechanical properties

c. Supplied for hydrostatic test. Steel pipes supplied as type a or b, if used to withstand liquid pressure, must also undergo a hydrostatic test.

3. Seamless pipes for specialized use include boiler pipes, chemical and power industry pipes, geological pipes, and oil industry 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 products like round bars, they are lighter in weight while maintaining the same bending and torsional strength, making them an economical section steel.
Broadly 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, pipe rings made from steel pipes can enhance material utilization, simplify production processes, save materials and processing time. Steel pipes are widely employed for this purpose.
