STRESS RELIEVING SERVICES
Tubes belonging to P-3 (1/2 Mo, tensile strength greater than 55 kg/mm 2) and above is advisable to undergo post weld heat treatment to:
- Reduce "locked-in" stresses at the heat-affected zones
- To reduce distortion during subsequent assembly and installation
- To enhance corrosion resistance
The furnace should be of the multiple burners with controls to be able to:
- Heat the complete assembly as a unit
- Control the rate of increase/decrease in temperature of the furnace
- Maintain a relatively uniform temperature inside the furnace (difference in temperature at points 15 feet apart should not be greater than 50 C.

Capacity: 50 Tons
Inside Dimension: 3.9m X 5.5m X 14.875m L
Number of Burners: 18 (9 each side)
