Sir , doubt , What I uderstansd is if material is preheated for thickness between 32 mm to 38 mm then pwht is not required , unless UW 2 applies , Am i correct.

[@faizali5302]

sir how do you calculate for " 15 mm - 9 Minutes" ?

[@veeraa9829]

My vessel SA516 GR 70, shell 22 thk, medium : ethanol ,For this case PWHT is required...?

[@weldinginspectionndt7376]

Refer NACE RP 0472

[@shaikazmatullah9679]

how did you calculate 15mm for 9 min kindly explain

[@pradeepreddy8651]

For upto 2" 2hrs + 15 min Our thickness 65mm Upto 2" ( 50.8mm) 2hrs Remaining thickness (14.2mm) As per condition over 2" Every 1" 15 minutes 1 minute =0.59mm 14.2*0.59 =9 minutes approximately Total 2hrs 9minutes

[@TrendsettlerNMT]

Here is the calculation which is given by pradeep

[@kabeershamsudeen6850]

how got 9 minute for 15mm?

[@TrendsettlerNMT]

15 mins for additional inch(25.4mm)hence for 15 mm thickness = 25.4 mm thickness 15 min Then for 15mm how much? 15*15=225 / 25.4 = 8.85 then 9 mins

[@mateoaguado8458]

The calculation should be: 15minutes / 25.4mm = .59055 then multiply by 15mm = 8.858 or 9minutes
