Seamless steel tube is a round, square, rectangular steel with a hollow section and no joints around it. Seamless steel tubes are made by punching steel ingots or solid billets and then hot rolled, cold rolled or cold drawn. Seamless steel tubes have a hollow cross-section and are used in a large number as pipes for conveying fluids. Compared with solid steels such as round steel, steel pipes have a lighter weight when subjected to the same torsional strength, and they are economical cross-section steels and widely used in the manufacture of structures. Parts and mechanical parts such as oil drill pipes, automobile drive shafts, bicycle racks, and steel scaffolds used in construction.
Small-caliber seamless steel pipe material: 10# 20# 35# 45# 16Mn 27SiMn 15CrMo 12Cr1MoV 10CrMo910 T91 P91 J55 K55 Q345 Cr5Mo2) 20#, 35#, 45#, 16Mn, 27SiMn3) 10#, 20#, 35#, 45#, 16Mn, 27SiMn, 12Cr1MoV, 10CrMo910, 15CrMo, etc.
Small-caliber seamless steel pipe weight calculation formula: [(outer diameter - wall thickness) * wall thickness] * 0.02466 = kg/meter (weight per meter)
Small-caliber seamless steel tube general specifications:
The outer diameter between (6mm-89mm) everyone used to call it a small diameter seamless tube, because his diameter is smaller.
Wall thickness (1mm-12mm) can also be divided into: small diameter thick-walled seamless pipe, small-caliber thin-walled seamless pipe.
