DIN 1630 ST52.4 seamless steel pipe is a long steel with a hollow section and no joints on the periphery. DIN 1630 ST52.4seamless steel pipe has a hollow section and are used in large quantities as pipes for conveying fluids. Compared with solid steel such as round steel, steel pipes have the same bending and torsion strength and lighter weight.
DIN 1630 ST52.4 seamless steel pipe is a kind of economical section steel, which 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.
DIN 1630 ST52.4 seamless steel pipe is widely used. General-purpose seamless steel pipes are rolled from ordinary carbon structural steel, low-alloy structural steel or alloy structural steel, and have the largest output. DIN 1630 ST52.4 seamless steel pipe is mainly used as pipelines or structural parts for conveying fluids.
According to DIN 1630 ST52.4 seamless steel pipe is 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.
