RE: [MW:31230] Combination of PQRs

Hello KK,

HIC testing usually does not apply or procedure qualification according to Sec-IX or even as per oil and gas industry standards, say NACE MR 103 , API(RP-582). Common industry document for HIC testing is NACE TM -0284, which calls for HIC testing on parent metals, plates/ pipes etc.

How does this idea of HIC testing originate? Is it possible for you to share any specific or relevant document?

Thanks.

Hi,

Yes, Piping requirements.

SA 516 gr 60/70. and according to ASME Sec.IX and ASME B31.3.

The main PQR is qualified with PWHT, but not HIC tested.

And I have additional PQR with HIC tested, but not qualified with PWHT, and no other lab test reports like a mechanical test, bend test, and hardness test report, shall I combined this PQR to my WPS.

Please looking you feedback.

Thanks

Kiran

Hi,

Please specify the material grade and the design code.

As you have mentioned Line class, I presume you are talking about piping .

Hi Experts,

"Good Morning"

According to my line classes, I required NACE+HIC+PWHT Wet H2 services.
What is the test shall be conducted according to the standard to meet the requirements?

I have one PQR with NACE+PWHT+Wet H2S services, but not HIC test.
In addition, I have qualified one HIC tested PQR without PWHT no other lab test certificates, shall I combined this PQR to the above requirements( NACE+HIC+PWHT+wet H2S).
For your information, the HIC test is an additional requirement of our specifications.
Please looking your feedback on my above query.

Thanks and Regards
Kiran
