Seamless steel tubes are very versatile. General purpose seamless steel tubes 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 transporting fluids.
According to different uses, they are divided into three categories:
a. Supply according to chemical composition and mechanical properties;
b. Supply according to mechanical properties;
c. Supply according to hydraulic test. For steel pipes supplied according
to categories a and b, if they are used to withstand liquid pressure, hydraulic tests are also required.
Special seamless pipes include boiler seamless pipes, chemical power, seamless pipes for geology and seamless pipes for petroleum.
Fluid seamless steel pipes have a hollow cross section and are widely used as pipelines for transporting fluids, such as pipelines that transport oil, natural gas, gas, water, and certain solid materials. Compared with solid steel such as round steel, steel pipe is lighter in weight when it has the same flexural and torsional strength. It is an economical cross-section steel and is widely used in the manufacture of structural parts and mechanical parts, such as petroleum drill rods, automotive transmission shafts, and bicycles Steel pipes and other scaffolds used in building construction to make ring-shaped parts can improve material utilization, simplify manufacturing processes, save materials and processing hours, and have been widely used in steel pipes.
