Hello everyone, 20 year ME/PM background in oil/gas where I've been only exposed to a couple canned project management tools, homemade excel based scheduling tools and failed attempts at MS project. We have a robust erp system with accurate labor hour buckets for manufacturing and currently...
Hey everyone,
My customer is requesting a specific Hydrotest Nozzle Pipe with PipeCap and reinforcement plate. They are specifying welding and material thickness inwhich I need to verify since this is an ASME pressure vessel. see below link for a visual.

Nozzle Pipe Cap: SA234, 6" XH...
I am hoping to gain alittle more on the intent of the Brinell hardness testing for what they classify as "chromium steels." I assume someone is making very specialized Cr steel pressure vessels, but why just those 3 types? It seems like the intent is check tensile/yield strength of the plate...
I've always been taught that you want to keep all nozzle connections on a pressure vessel the same for safety and engineering 101 principles. I currently have a customer that wants all nozzles 1-2" to be 300#, and all 4-8" to be 150# when specified as minimum pressure,say 50psi. I always...
Hey everyone, I just ordered a hard print that will be here in a week or two but can someone tell me the requirements listed by this Annex J? I am currently trying to satisfy a pressure vessel for SK CRN. Looks to be a (new)requirement I was not aware of under the Special Circumstances...
Hello all! I found another topic with vagueness that I want to provide calculations for, with the purpose of standardizing routine torque checks... SA105 Shoulder Plugs for Boxed pressure vessels, more precisely, heat exchangers. A very grey area as far as where original calculations came from...
Hey everyone. I have an old 80's heat exchanger I am reviewing and it was ASME nameplated for -60F MDMT. This is alittle colder than I have dealt with so I am seeking advice. The box's plate/nozzle pipe/flanges have been impact tested per UG-84 to -60F MDMT but I am curious about the...
Recently had a request to replace a pressure vessel. It is made of RMT A-500 Gr B, relatively low pressure, welded end caps, non-code BUT specification sheet shows -20F MDMT. Now technically speaking, since its not code, there is no requirement for impact testing...or in addition, there is no...
