Changzhou Chengxin Metal Products Co., Ltd. focuses on hydraulic cold drawn pipe and high-frequency welded pipe.
What are thick walled steel pipes and their applications?
Thick wall
Steel Pipe refers to the steel pipe whose ratio of outer diameter to wall thickness is less than 20. It is mainly used as drilling pipe for petroleum geology, cracking pipe for petrochemical industry, boiler pipe, bearing pipe and high-precision structural pipe for automobile, tractor and aviation.
The difference between thick walled steel tubes and thin walled steel tubes is the thickness of the
Steel Tube wall. Generally speaking, thin walled steel tubes are cold drawn. Thick walled steel tubes and thick walled steel tubes generally
With hot rolling technology, if the unit of measurement is used to distinguish, it is generally believed that the wall thickness/pipe diameter equal to 0.02 is the watershed between thick wall steel pipes and thin wall steel pipes, the wall thickness/pipe diameter less than 0.02 is thin wall steel pipes, and the wall thickness/pipe diameter greater than 0.02 is thick wall steel pipes. In terms of use, thin wall steel pipes are mostly used for pipes. However, thick walled steel tubes are mostly used as blanks for hollow parts. Used on pressure bearing and important pipelines.
Thick wall steel pipes are mainly used in water works, petrochemical industry, chemical industry, electric power industry, agricultural irrigation and urban construction. For liquid transportation: water supply and drainage. For gas transmission: gas, steam, liquefied petroleum gas. For structure: for pile driving pipe and bridge; Pipes for wharfs, roads, building structures, etc.
