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.
