Oxygen Pressure Vessel
Oxygen Pressure Vessel
(OP)
Hi everyone!
I am looking for any special requirements of designing and constructing oxygen pressure vessels. The vessel needs to be pressurized up to 10 BAR and the operating temp. is -20 to 40 C. It is going to be tested and operating in EU so I am not sure which code should apply. Any special requirements to prevent the PV from contact with fire?

I have found this on the internet:
PD 5500 was formerly a widely used British Standard known as BS 5500, but was withdrawn from the list of British Standards because it was not harmonized with the Europeran Pressure Equipment Directive (97/23/EC). In the United Kingdom it was replaced by EN 13445. It is currently published as a "Published Document" (PD) by the British Standards Institution.

Can you tell me what does MoC stand for? The vessel will be located in different EU countries, including the UK.

But "technically" high pressure oxygen is also not "flammable" ... by itself.
It just makes anything around it flammable, or like the ulmar rubber seals used in the early X-1 planes, explosive if touching the oxygen.
All of the usual HP gas rules apply as they would on a high pressure nitrogen bottle (direction of threads, NDE, etc. But your fabrication and even cleaning instructions and painting and preservation instructions need to be explicit about what is permitted to be used: which solvents, what gaskets, what torques, etc.

Which recognised standard you use is up to you, ASME VIII is fine but EN 13445 "should" be the easiest as it is harmonised with PED. Again, for welding, ASME IX is fine but you need to jump through some more hoops to meet the PED requirements.

The problem with sloppy work is that the supply FAR EXCEEDS the demand
