Hardness Test after PWHT
Hardness Test after PWHT
(OP)
Hello,
I have to send all the BW joint CS/SS pipes (thickness is less than 3/4") for PWHT. The code says PWHT is not required if the thickness is below 3/4", but it's client requirement so have to do it.
Can anyone tell me how much hardness is required for testing? the services are Sour Gas and Amine.

When you PWHT it, you must check the hardness to make sure it is in the correct.
