Manufacturing Process

Process Detail

Hot Piercing is used for manufacturing hot finished tubes and pipes.

Cold rolling is a widely used step for the production of seamless, cold-finished, high alloyed stainless steel and nickel based alloy tubes and pipes, with a process able to reach lower outside diameters and tighter tolerances than the hot pierced hollows.

Cold drawing is used to obtain tight tolerance ranges , for outside diameters but also for wall thicknesses.

Annealing is to release the stress after cold process.

Zhongrui has always been trying to save cost for its customers while making no compromise on product quality by improving and perfecting its production system and bringing in new technologies since it started.
