Re: [MW:24695] 24682] SSC test acceptance limit.

"SSC test including SOHIC test to be conducted on the additional test specimen" as per project specification.

Remaning tests like Tensile,Macro,Hardness,Impact are all accepted.

Now we need any change in WPS or to go for the retest(30 days + PQR preparation). we have used BOHLER welding electrodes tested earlier for SSC test.

Please give your suggestion to proceed further.

Thanks lot.

Hi Kalemullah,

MR-0175/ISO 15156 specifies that SSC/SOHIC testing should be done as per NACE TM-0177.This testing requirements are quite severe. You need to go through the results

SOHIC testing on the PQR was originally called for in your project specifications??

Appreciate your response.

Thanks.

Dear Experts,

We are doing pipeline project for international client at UAE. We have completed

Now the PQR test conducted for the SSC test and SOHIC test.

But the test lab informed that linear indication was observed in two test specimen after 30 days SSC test.

Now the client instructed

Please suggest any acceptance criteria and resolution. Failure of the test will result huge impact on the 400 welded joints. Please suggest.

Pipeline Material:API 5L Gr.B X-60 as per shell standards.
