Post Weld Heat Treatment shall be carried out as per the approved specified cycle of the various vessels (Thickness: 45mm, Diameter: 4 Mtrs, Length: 10 Mtrs ) and tank – (Thickness: 10mm, Diameter: 7.5 Mtrs, Height: 13 Mtrs) job executed by SHW A large variety of Tanks, LPG Bullets, Pressure Vessels, HemiSpheres and welded fabrications structures can be subjected to Post Weld Heat

Treatment by external firing method ” SHW’ High Velocity Oil Burners. The temperature uniformity that can be achieved by this method ensures that even the tightest standards and specifications are comfortably satisfied. The method used to POST WELD HEAT

TREATMENT would be by using of a High Velocity Oil Burner inserted into the vessels manhole, through out the heating, soaking and cooling cycle the expansion and contraction of the vessels must be closely monitored and controlled to avoid any disability of the job. We have carried out a number of “POST WELD HEAT TREATMENT ” with Oil fired external method Stress Relieving operation successfully.
