The application of seamless steel pipe

Seamless steel pipes are widely used. Seamless steel pipes for general use are rolled by ordinary carbon structural steel, low alloy structural steel or alloy structural steel, with the highest output, and are mainly used as pipes or structural parts for conveying fluids.

According to different uses, seamless steel pipes are supplied in three categories:
a. Supply by chemical composition and mechanical properties
b. Supply by mechanical properties
c. Supply by water pressure test

Steel pipes supplied by class a and class c should also be subjected to hydrostatic test if they are used for liquid pressure.

Seamless pipes for special purposes include seamless pipes for boilers, seamless pipes for chemical and electric power, seamless pipes for geology and seamless pipes for petroleum, etc..

Seamless steel pipes have hollow sections and are widely used as pipes for conveying fluids, such as oil, natural gas, coal gas, water and some solid materials. Compared with solid steel such as round steel, steel pipe has the same bending and torsional strength and lighter weight, so it is an economic section steel.

Seamless steel pipes are widely used in the manufacture of structural and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffolding used in construction. Using steel pipe to manufacture ring parts can improve material utilization rate, simplify manufacturing process, save material and processing time. Steel pipe has been widely used in manufacturing.
