Different properties:
- Carbon steel pipe: It is made of steel ingots or solid round steel perforated into capillary tubes, and then hot rolled, cold rolled, or cold drawn. 2. Stainless steel pipe: It is a hollow, elongated, circular steel material. 3. Seamless steel pipe: A steel pipe made of a single piece of metal with no joints on the surface.
Different characteristics:
- Carbon steel pipes: Carbon steel pipes are divided into two categories: hot-rolled and cold-rolled (drawn) steel pipes. Hot rolled carbon steel pipe is divided into general steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, petroleum cracking pipe, geological steel pipe and other steel pipes. 2. Stainless steel pipe: among the stainless steel pipe standards, Brinell hardness hardness is the most widely used. The indentation diameter is often used to represent the hardness of the material, which is intuitive and convenient. However, it is not suitable for steel pipes made of harder or thinner steel. 3. Seamless steel pipes: According to production methods, seamless pipes are divided into hot rolled pipes, cold rolled pipes, cold drawn pipes, extruded pipes, top pipes, etc. According to the cross-sectional shape, seamless steel pipes are divided into two types: circular and irregular. The irregular pipes have various complex shapes such as square, elliptical, triangular, hexagonal, melon seed, star, and finned pipes. Maximum diameter up to 650mm, minimum diameter 0.3mm
