The biggest 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, while thick walled steel tubes generally use hot rolling technology. If the unit of measurement is used to distinguish, it is generally believed that the wall thickness/pipe diameter equal to 0.05 is the watershed between thick walled steel tubes and thin walled steel tubes. Thin walled steel tubes with wall thickness/pipe diameter less than 0.05 are thin walled steel tubes, and thick walled steel tubes with wall thickness/pipe diameter greater than 0.05 are thick walled steel tubes. In terms of use, Thin walled
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.
Purpose Edit Broadcast
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.
