🔥 ASME Section VIII Div 1 (1,150°F Soak Temp, 1 Hr/Inch Thickness, Heating Ramp)

Post-Weld Heat Treatment (PWHT) Calculator

Calculate thermal stress relief heating cycles for heavy-wall pressure vessels and piping under ASME Section VIII Div 1 Table UCS-56: calculate minimum holding soak time (1 hour per inch of weld thickness at 1,100°F - 1,200°F), controlled heating/cooling ramp rates (<400°F/hr / thickness), thermocouple placement, and specialty heat treating profits.
