304 Welded Stainless Steel Pipe/Tube




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.
