Stainless steel seamless pipe is a long strip of steel with a hollow section and no joints around it.

Features of stainless steel seamless pipe:

The thicker the wall thickness of the stainless steel seamless pipe, the more economical and practical it is, and the thinner the wall thickness, the higher its processing cost;

The process of stainless steel seamless pipe determines its limited performance. Generally, the precision of seamless steel pipe is low: uneven wall thickness, low brightness inside and outside the pipe, high cost of fixed-length, and there are pits and black spots on the inside and outside that are not easy to remove;

The inspection and shaping of stainless steel seamless pipes must be processed offline. Therefore, it reflects its superiority in terms of high pressure, high strength, and mechanical structural materials.

Seamless steel pipes are widely used. General-purpose seamless steel pipes are rolled from ordinary carbon structural steel, low-alloy structural steel, or alloy structural steel, with the largest output, and are mainly used as pipelines or structural parts for conveying fluids.

There are three types of supply according to different uses:

A. By chemical composition and mechanical properties;

B. By mechanical properties

C. Press water pressure test

Steel pipes supplied according to categories a and b, if they are used to withstand liquid pressure, shall also be subjected to a hydrostatic test. Special purpose seamless pipes include seamless pipes for boilers, seamless pipes for chemical power, seamless pipes for geological use, and seamless pipes for petroleum.

Seamless steel pipes have hollow sections and are widely used as pipelines for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water, and certain solid materials. Compared with solid steel such as round steel, the steel pipe is lighter in weight when the bending and torsional strength is the same and is economical section steel.

It is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile transmission shafts, bicycle frames, and steel scaffolding used in construction. The use of steel pipes to manufacture annular parts can improve material utilization, simplify manufacturing processes, and save materials and processing. Man-hours have been widely used to manufacture steel pipes.
