The Benefits Of Pre-Heat Treatment

• Reduces the levels of thermal stress
• Compensates for high heat loss
• Minimizes the rate of weld hardening
• Reduces the porosity of the weld
• Reduces hydrogen cracking
• Improves micro-structure of heat-affected zone

Electrical Pre-heat and PWHT of Pressure Vessels

During the construction or repair of columns, vessels and apparatus working under pressure, sphere tanks, various case heat exchange equipment technical documentation often requires post weld heat treatment of all welded joints or the entire product. Each work is preceded by detailed engineering research. The most optimal solution is selected based on the job conditions.
