Seamless steel pipe is a round, square and rectangular steel with a hollow section and no joints on the periphery. Seamless steel pipes are made of steel ingots or solid tube billets through perforation into capillary tubes, and then made by hot rolling, cold rolling or cold drawing. Seamless steel pipes have a hollow section and are mostly used as pipelines for conveying fluids. Compared with solid steel such as round steel, steel pipes have the same bending and torsion strength and lighter weight. They are economical cross-section steels and are widely used in manufacturing structures. Parts and mechanical parts, such as oil drill pipes, automobile transmission shafts, bicycle frames, and steel scaffolding used in construction.
Comparison of precision steel pipe and seamless steel pipe
1. The main feature of seamless steel pipe is that it has no welded seams and can withstand greater pressure. The product can be a rough cast or cold drawn part.
2.Precision steel pipe is a product that has appeared in recent years. The main feature is that the inner hole and outer wall dimensions have strict tolerances and roughness.
Tips:ASME SA106 seamless carbon steel pipe is some sort of hollow section steel material with no seam throughout. It can be in round, square or rectangular shape. The SA106 series is divided into three quality levels: A, B, and C, namely: SA106 Gr A, SA106 Gr B, and SA106 Gr C.
