Marking of rupture disk per Canadian B51
Marking of rupture disk per Canadian B51
(OP)
We have a high pressure, 30000 psi panel, made up of High Pressure Equipment and Autoclave products (nipples, valves, tees, ells, etc). The local Ontario TSSA inspector wants the rupture disk to be marked. The disk is about 3/8 in diameter and comes with a plate that details the capacity of the rupture disk. Still he wants the thing marked.
Have any of you any experience on what has / can be done to satisfy this requirement?
Thanks.

If the system consists only of piping/tubing, and the disc serves only to protect piping/tubing, you have reasonable grounds to argue with the TSSA inspector, as there is no requirement I'm aware of that a relief device protecting piping/tubing must be ASME certified.

I did find that Zook manufactures a 1/4 inch rupture disc that is both ASME UD stamped and has an Ontario CRN.
