How to pressure-test a 500-kilogram hydrogen pipeline?
There are specialists who handle pressure reduction; usually, the company gets in touch with them for on-site service
Find a professional company for pressure testing; they have complete equipment and it’s convenient, or have the manufacturer carry out the pressure testing before shipment
500 kilograms is fine; conducting a hydrostatic test is not difficult.
I’ve never seen pressure pipes this tall
According to the regulations, in addition to water pressure, there should also be a leakage test, right?
Use a plunger pump with higher pressure; if a larger volume is required, an ordinary pump can be used to reach several kilograms first, after which a plunger pump will make the process much faster.
It would be too dangerous to use a pressure of 500 kilograms; helium testing can be used as a substitute. The welds need to be inspected by radiography.
This is from this training; a colleague asked the teacher a question that the teacher had never encountered before. So I would like to ask Teacher Ying. These types of pipes are generally manufactured by certain monopolistic companies; other companies do not have the opportunity to do so.
Helium testing is a leak test to check airtightness, while water pressure testing is a strength test.
