[MW:8269] RE: 8267] PWHT and RT

Hi Sagar,

 

As per ASME31.3, you will find PWHT before RT, But suggestion is to you follow your Project Specification or other wise Construction Code of your project.

Same issue came in our project also.

 

Regards,

Ahmed

Subject: [MW:8267] PWHT and RT

 

Hi,

 

I have a doubt regarding PWHT and RT. We are welding P1 Material Pipes which has thickness more than 19mm so we are performing PWHT for the same. But my question is regarding when to take RT? Can we accept the joints which is radiographed before PWHT and  MPI after PWHT. Or will we have to perform the RT only after PWHT of the joints? Please advice me regarding this and provide the supporting clause.

 

Thanks and Regards,

Sagar.
