Cr Coil For Pipe Industry

A Cold Rolled (CR) Coil used in the pipe industry is a flat steel product that serves as the raw material for manufacturing high-quality steel pipes and tubes, especially Electric Resistance Welded (ERW) pipes.

Here is a description of its key characteristics and role in the pipe industry:

1. Manufacturing Process

• Cold Rolling: The CR coil is produced from a Hot Rolled (HR) coil. The HR coil is first pickled (to remove surface scale/oxide) and then passed through rollers at room temperature (below the steel's recrystallization temperature).

• Effect: This cold-working process compresses the steel, reducing its thickness and significantly improving its properties.
