The difference between hot rolled and cold rolled tubes

1. Dimensional accuracy: The dimensional accuracy of cold-rolled steel pipe is high.

2. Appearance: The surface of cold-rolled steel pipe is bright, and the surface of hot-rolled steel pipe has obvious scale or red rust.

 

2. Caliber size: The caliber of cold-rolled steel pipe is smaller than that of hot-rolled steel pipe (mainly different in machinery, each has its own special).

 

4. Price: Cold-rolled steel pipe is 1,000-2000 one ton more expensive than hot-rolled steel pipe.

 

Application: Hot-rolled steel pipes are used in places where the size requirements of fluid conveyance and mechanical structures are not high. Cold-rolled steel pipes are used in precision equipment, hydraulic systems, pneumatic and other places.
