[MW:7505] PWHT

Dear Sirs,

 

We have Planned to Stress relive the Pipe butt joint of SA 335 Gr P91and Dia.323.9X33.3 at Soaking Temp:745°C ±10°C and soaking time:90mints. But by mistake while in process the operator has completed the Stress reliving at Soaking Temp:695°C ±10°C and soaking time:90mints.

 

For this can go to Re- stress reliving or can I accept as in condition(Request to guide me by mentioning the related standard) . I request any of us to guide me in this case to proceed further.

 

 

Thanks and Warm Regard’s,

 

K.GANESAN/QA&C,
