Technical requirements for the manufacture of low-temperature pressure vessels
Thread Content
Everyone, what are the specific technical requirements for manufacturing 16Mndr pressure vessels? What is the specific source? Different from ordinary container manufacturing
HG20585-2011
General provisions: 150.3 – the last appendix; it can also be found by going back from 150.4. Material requirements: 150.2; Manufacturing and inspection requirements: 150.4 – all of these are listed together with those for ordinary containers. If it is a low-temperature container, refer to the above provisions
16MnDR is generally used in low-temperature vessels. The specific requirements for this material relate to the impact temperature of the steel plate, the grade of the forgings, and for flaw detection a coverage of 50% is typically required; it is also necessary to consider whether heat treatment is needed. The source is indicated above; if it is designed for 150
