Thick-walled Steel Pipe

Thick-walled steel pipe, the pipe diameter and wall thickness ratio of less than 20 like that steel pipe known as thick-walled steel pipe. Mainly used for petroleum geological drilling tube, petrochemical cracking tubes, boiler tubes, bearing tubes and automotive, tractors, aviation and other high-precision structural control.

The biggest difference between the thick wall steel pipe and thin-walled steel pipe is the wall thickness, in general, are thin-walled steel pipe belongs to drawing technology, and thick-walled steel generally use hot-rolled technology, if it is measured wall thickness / pipe diameter is equal to 0.05 that is a thick-walled steel pipe and thin-walled pipe watershed, wall thickness / diameter less than 0.05 that is a thin-walled steel pipe, thicker than the steel pipe, in use On, the thin-walled steel pipe used for pipe. The thick-walled steel pipe and more hollow parts used in the blank. Pressure and the use of important pipelines.

Thick-walled steel pipe is mainly used in water supply engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, urban construction. For liquid delivery with: water supply, drainage. For gas transportation with: gas, steam, liquefied petroleum gas. For structural use: for piling, as a bridge; terminals, roads, buildings and other structures.
