Calculate ASME B31.1 power piping design pressure from the design temperature. The design stress (SE) is calculated from tables A-1 to A-9. For temperatures above the data range, select either constant value, constant slope, or zero value (engineering judgement is required). The weld factor W is relevant for temperatures in the creep range.

t= (1200*114.3)/ {2 (19000*1*1+1200*0.4)}=3.52 mm; Hence calculated thickness (t)= 3.52 mm Step 2. Add the **corrosion** to the calculated thickness. t c = t + c = 3.52 + 3 tc = 6.52 mm Step 3. Add the mill tolerance to the thickness after adding the **corrosion** value. t m = t c + 12.50 % of the pipe thickness.
