Meaning of verification and supplementary testing for pipeline components
Thread Content
Let’s discuss what kinds of tests are primarily referred to as the verification and supplementary testing of pipeline components in SH3503 Not very clear
This one, I guess, was copied from ASME B31.3. . Verification tests mainly involve type tests conducted through blasting. Supplementary inspections are those inspections that take place in addition to the mandatory inspections. For example, for that weld seam where 100% RT is required, then you need to carry out a surface inspection. .
For example, alloy steel undergoes spectral testing, namely PMI, while low-temperature fittings are subject to low-temperature impact testing
