The use and production process of seamless carbon steel pipe
Seamless steel pipe is perforated by the whole round steel, and the steel pipe with no weld on the surface is called seamless steel pipe. According to the production method, the seamless steel pipe can be divided into hot rolled seamless steel pipe, cold rolled seamless steel pipe, cold drawn seamless steel pipe, extruded seamless steel pipe, pipe jacking and so on. According to the section shape, the seamless steel pipe is divided into two kinds of round and shaped, shaped pipe has square, oval, triangle, hexagonal, melon see

Carbon Seamless Steel Pipe Knowledge
Seamless steel tube is a round, square and rectangular steel with hollow section and no joints around. 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 steel such as round steel, steel pipes have a lighter weight when subjected to the same flexural and torsional strength. They are economical cross-section steels and widely used
Key points of seamless steel pipe storage
