Lifting Levers on Steam Relief Valves 1

[sshep]

My Friends,

Recently I have talked with two operations people from different sites who tell me that they no longer allowed lifting levers in steam service, but were not sure why. Every site I have ever worked at generally provided lifting levers for steam relief valves to allow an opportunity to reseat without shutting down.

I would like to know the policy at other sites, and understand why some companies appear to have stopped using the lifting lever feature. Any input is appreciated.

best wishes,

sshep,

Did you see this old thread on the subject? thread1203-157185

If it's a Code requirement, how can companies in an ASME jurisdiction not comply?

Good luck,
