Hey guys, propane is moderately hazardous and flammable – why are leakage tests conducted?
Thread Content
GB150 stipulates that it is of extremely high hazard and allows no trace leakage. Why is this?
I’m not sure; where did I see that the test had to be disclosed? If the requirements are artificially increased, it is safer from a safety perspective – there’s no problem with that. Also, could it be because minor leaks are not allowed, due to the explosive nature of the medium, or because of strong permeability?
“It’s difficult to ensure no minor leaks are allowed.
According to the standard of 20580 to 20585, it seems that a leakage test is required; if this standard is not specified, the test can be omitted.
It is fine to require leak tests for moderately hazardous media and explosive media; the standards represent the basic requirements. Propane is the main component of liquefied petroleum gas, and pipe flanges must also comply with the requirements of clause 3.2.5(2) of the pressure vessel regulations.
Yes, it seems that the rule states that if something is explosive, then a leak should be reported; however, nothing is mentioned regarding whether it poses a high level of danger

Some organizations may not do this; ethanol is more common, and it’s quite troublesome to use it. It is said that in the new draft of 20584, the wording seems less stringent, as some organizations have complained that the requirements were too strict
Is there an electronic version of the draft for comments: handshake
