Our advantage process

(1).Internal Leveling

Leveling within is the use of specialized equipment in the flattened seam weld on a pressurized multipass rolling, eventually leveling welding, inner and outer surface smooth weld without delamination.

(2).Annealing Oline

Stainless steel tubing from 1040-1080degree celsius and annealing foe processing gas shield to eliminate the pipe stress, reduce the hardness of the pipe, the surface brightness enhancement purposes.

(3).Quasi-plasma Welding

It can be different grits, polished inside and outside different surface treatments.

(4).Polished Inside and Outside

It can be different grits, polished inside and outside different surface treatments.
