Product Applications

Low or medium pressure boilers

Seamless steel pipes are widely used

1. General-purpose seamless steel pipes are rolled by 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.

2. According to different purposes, it can be supplied in three categories:

a. Supply according to chemical composition and mechanical properties;

b. According to mechanical performance;

c. According to the water pressure test supply. Steel pipes supplied according to categories a and b. if used to withstand liquid pressure, shall also be subjected to a hydraulic test.

3. Special-purpose seamless pipes include seamless pipes for boilers, chemical and electric power, seamless steel pipes for geology, and seamless pipes for petroleum.
