What are the precautions for the nozzles of cryogenic pressure vessels? Everyone, please help list them so I can check if I’ve missed anything!
Have you listed what’s on your mind so that others can help analyze it? What are the conditions regarding temperature, pressure, medium, and material?
Liquid nitrogen, 2.5 MPa, 30 m3, horizontal type.

Stainless steel connectors for liquid nitrogen indicate the standard being used, as well as the condition of delivery...
There are no additional requirements. . Choosing the right material is key. . .
Liquid nitrogen is at -196°C at atmospheric pressure, and at 2.5 MPa it is around -153°C
Material S30408 should work. I don’t know where this pressure of 2.5 MPa comes from.
Material selection, installation/welding methods, inspection requirements, selection of connection components (flanges, bolts, gaskets), selection of insulation structure
