Thanks Jop,

Alright I understand. During the plant operation if they find some leaks in hydrogen class service (i hope in any pressurized service), the solution normally comes to steam ring.

Now normally ‘quality’ pipers tend to be aware of possible problems during plant operation and their solutions, and tend to provide facility for those during the layout e.g

– maintaining a std. distances b/w lines, if there is a need of any flanged item in future.
– providing flg. spools to allow for removal of gate valves and check valves. specially near to rotating equipment

similarly for what pressure rating a piper should be aware of any possible requirements of steam rings b/c of flg. leakage (in case).
and How can a piper facilitate this requirement during initial piping layout.

Regards
