Re: New at PipingDesign.com: 21 July 2001

this is fine. but i have seen some piping engineer that is focus only with piping and nozzle load forgetting that AST falls under a separate standard - the API 650. Take the case of a large storage tanks that is leaking and will require repair. After detailed study, cocnluded that the best option for repair is using a double tank bottom. of course the nozzle elevation will now change, and the piping engineer who was consulted said no problem - will just reroute  the piping forgetting that tank repair follow another code 9actually its an inspection) - which is the API 653. And guess what, API 653 is actually concern with the distance between weld of the nozzle and the bottom plate to ensure nozzle entigrity which the pipinmg engineer is completelky unaware of. My point is, piping engineer should also be aware of equipment for which they are trying to protect (by ensuring the nozzle load is below allowable).
