Do chemical analysis _ Spectro or weight ana

PMI is not right method.

If you have neither any idea about pipe's material specification nor the material test certificate, it is not advisable to confirm the same with merely PMI or chemical testing. Please avoid this material to use as pressure part in your job.

Thanks,

Dear Rajnish,

Its not our in-house materials, this is the existing material used in Loading Arm. Client wants us to replace it with same one. they just provided the PMI on XRF method, however we have requested for OES and a sample for chemical analysis to look further.

Thanks for your support

Best Regards

Dhana
