[MW:25395] RE: 25392] PWHT

Hello, ZHY370137,

 

I'm not sure why you're asking this question is general forum, when your contract is bound by your clients' specifications and project requirements. Aramco has very comprehensive specifications for almost everything. If Aramco SAES-W-012 is applicable for your project you need to what's needed as per this spec.

 

What's  the design code, of the pipeline B-31.4 or 31.8? And what're the Aramco specifications applicable?

 

Usually for sour service hardness control is "mandatory" to mitigate the HIC. One of the effective ways to ensure hardness control is PWHT, unless vendor is able to prove otherwise.

 

Appreciate your response.

 

Thanks.
