What Are the Uses of Seamless Carbon Steel Pipe?

Seamless carbon steel pipe is made of steel ingots or solid tube blanks through perforation to make capillaries, and then hot rolled, cold rolled or cold drawn. Seamless carbon steel pipe plays an important role in China's steel pipe industry.

Seamless carbon steel pipe

Seamless carbon steel pipe (Seamless carbonsteel pipe) is made of steel ingots or solid tube blanks by perforation to make capillary tubes, and then made by hot rolling, cold rolling or cold drawing. Seamless carbon steel pipe plays an important role in China's steel pipe industry. According to incomplete statistics, there are about 240 seamless carbon steel pipe production enterprises in China, about 250 sets of seamless carbon steel pipe units, and an annual output capacity of about 4.5 million tons. In terms of caliber, those with <76 account for 35%, and those with <159-650 account for 25%. In terms of variety, 1.9 million tons of general-purpose pipes, accounting for 54%; 760,000 tons of petroleum pipes, accounting for 5.7%; hydraulic props,

The specifications of seamless steel tubes are expressed in millimeters of outer diameter * wall thickness.

Classification of seamless carbon steel pipes : seamless steel pipes are divided into hot rolled and cold rolled (dial) seamless steel pipes.

Due to different manufacturing processes, seamless steel tubes are divided into hot rolled (extrusion) seamless steel tubes and
