Stainless Steel Pipe (welded) 10" NB to 24" NB. in schedule 5, Schedule 10, Schedule 20, Schedule 40 and also special wall thickness is formed on 800 M.T. Press Brakes Hydraulic Press in lenght upto 6.0 to 7.0 meters. This section produces S.S. pipes (welded) as per ASTM A-358 by TIG welding and filler materials is used. The large diameter pipe is then sized & straightened to meet ovality and dimensional requirements of the applicable specifications. Testing, according to specifications, is then performed by either X-ray or Hydrostatic method. Final marking to size, grade & specifications is done prior to final visual inspection before despatch.
