Seamless steel pipes have a wide range of applications.

1. Seamless steel pipes for general use are rolled from ordinary carbon structural steel, low-alloy structural steel, or alloy structural steel, with high production capacity, mainly used as pipelines or structural parts for transporting fluids.

2. According to different purposes, there are three types of supply:

a、 Supply according to chemical composition and mechanical properties;

b、 Supply based on mechanical performance;

c、 Supply according to hydraulic pressure test. Steel pipes supplied according to categories A and B, if used to withstand liquid pressure, also need to undergo hydrostatic testing.

3. There are various types of seamless pipes for specialized purposes, including seamless pipes for boilers, seamless steel pipes for chemical and electrical industries, seamless steel pipes for geological applications, and seamless pipes for petroleum applications.

Seamless steel pipes have a hollow cross-section and are widely used as pipelines for transporting fluids, such as oil, natural gas, coal gas, water, and certain solid materials. Compared with solid steel such as round steel, steel pipes are lighter in weight when their bending and torsional strength is the same, making them an economical cross-sectional steel.

Widely used in the manufacturing of structural and mechanical parts, such as oil drill rods, automotive transmission shafts, bicycle frames, and steel scaffolding used in construction, steel pipes are used to manufacture circular parts. This can improve material utilization, simplify manufacturing processes, save materials and processing time, and has been widely used in the manufacturing of steel pipes.
