Testing (Hydro) of a spare valve
Testing (Hydro) of a spare valve
(OP)
Hi All
Need a bit of opinion.
I've work at different companies and many have slightly different rules when it comes to using a spare valve (new or refurbished).
When a valve (out of storage) is to be used, it will need to undergo a hydro test if the last test was done on it more than a year ago.
Seems common in many industries. But I never found that requirement clause in the ASME Standard.

I don't think ASME has jurisdiction here as they're mostly involved in the construction of the valve.

*** Per ISO-4126, the generic term
'Safety Valve' is used regardless of application or design ***
*** 'Pressure-relief Valve' is the equivalent ASME/API term ***

There is no real reason why this valve needs a hydro test unless someone has lost the previous test results.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

These days there are a lot of good preservation products on the market that can inhibit corrosion in the store, but they need to be applied correctly and maintained, and each of these aspects is as important as the other. Irrespective, I think that a quick pressure test prior to installation pays dividends.
