Re: [MW:28162] PWHT required for HF service

Greetings,

For your mentioned thickness need pwht. 

If you ask regardless to thickness for hf which is to be understood hydrogen service yes required but not necessarily for p no 1,but yes our client requires for p3, 4,5abc.

So its your clients requirements and his spec to be followed. 

Thanks
