Thick-walled steel pipe, its pipe diameter and wall thickness ratio of less than 20, said the steel pipe is a thick-walled steel pipe. Mainly used in petroleum geological drilling pipe, petrochemical cracking pipe, boiler tube, bearing pipe and high-precision structural control of automobiles, tractors, aviation and so on.
The biggest difference between the thick wall steel pipe
and thin-walled steel pipe is the wall thickness, in general, are thin-walled steel bar 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, Thick-walled steel tubes and more hollow parts used in the blanks. Pressure and use of important pipes.
Thick-walled steel pipes are mainly used for water supply projects, petrochemicals, chemical industry, power industry, agricultural irrigation, urban construction and so on. For liquid delivery: water supply, drainage. For gas transportation: gas, steam, liquefied petroleum gas. Structural uses: Used for piling, bridges, docks, roads, buildings and other structures.
