Manufacturing of stainless steel welded tubes& pipes commence with the formation of welded mother tubes/pipes on continue tube mill from prime quality satinless steel strips, using the latest TIG welding technique for superior weld quality and 100% suasion,. Argon pursing is used to prevent any contaminatio of the welded area of the tubes. These tubes are then annealed at 1050 degree C-1100 degree C in continuous aneling arnica followed by immediate water quaenhching to prevent chromium carbibe precipitation. Then these tubes are straghtened in straightening machine. Finally these tub es are straightened in straightening machine. Finally these tubes picked in a picking solution made of Nitric Acid and Hydrofluoric |Acid. This removes the scales formed during annealing. These tubes are checked by quality control people for checking all the parameters.
