Which standards specify the retesting of materials?
Thread Content
Everyone, I’ve been working on pressure vessels recently and would like to ask: which standards specify the re-inspection requirements for steel plates and welding materials? It would be great if you could indicate where these specifications can be found
It is present in both the material specifications and those of GB150, as well as in the material and manufacturing inspection and acceptance procedures
Code for Fixed Pressure Vessels 2.1.2.1(4), 2.1.4(1), 2.1.1.4(2); GB150.2 and GB150.4 are also not listed here
Generally, only grade 4 forgings of three types of containers require re-inspection; this requirement applies to both 150 and large-size specifications
The reinspection of welding materials applies to welding materials used for low-temperature vessels, 150.4
Everyone is enthusiastic, which also demonstrates that many hands make light work.
