Re: [MW:33552] PWHT time calculation

As per 7.8.1, para 2,

rate of heating ia 560/2"= 280Deg.C

But there is a condition that "but in no case more than 220Deg.C per hour.

Hence you have to apply 220 Deg. C per hour.

Dear All

Please guide how to calculate the rate of heating for PWHT for below AWS d1.1

"Para 7.8.1 Above 600°F [3 1 5 °C] , the rate of heating in °F [°C] per hour shall not exceed 400 [560] divided by the maximum
metal thickness of the thicker part, in inches [centimeters ] , but in no case more than 400°F [220°C] per hour"

If the maximum thickness is 2 inches , how to calculate heating rate
