Welded pipes is carried out on sophisticated tube mills where the cold roll stainless steel strips are welded into tubes in a fully automatic process.

GANYEAH is also having the facility to supply tubes with lower residual stress values, which plays an important role in service life of Heat Exchange

The surface treatment is usually pickling or bright annealing. The polishing level is as follows: 180 # 320 # 400 # 600 # 400 #.
