In a perfect world people would replace this old iron with something safer, but the people who own these vessels are not the same people who understand the mechanical issues like those of us in this thread and on this forum. We can recommend they be removed from service due to all the...
Hey JT, I understand the issues regarding the material itself, The US Department of Commerce actually performed a detailed post accident analysis on the head of a steam boiler that was involved in a rail road accident on behalf of the Federal Railroad Administration. It goes into excellent...
Not sure, it was originally accepted for use in Ontario without it so they may let it slide, we are only shooting for an MDMT of -20°F anyways as that was what the vessel originally was and we don't want to perform an alteration.
Geoff, thanks for your input, used equipment is always fun haha!
Hey Geoff, So I have spoken with TSASK, they require all used pressure equipment being imported into SK to have a valid SK CRN#. It was discovered that the vessel did not have a SK CRN number so we are required to submit as-built drawings as well as code calculations, TSASK will review and...
As far as I can tell by looking at the U1A it specifies UW-12(A) & (b) for my code paragraph so I'm assuming this would be as JStephen Stated having the long seams fully radiographed and the circ seams spot radiographed. this would qualify as full radiography as per UW-11(A)(5)(-B) (in the...
Part of the issue is we have no knowledge of the extent of the radiography beyond the P.X.R stamp so we have to assume that spot radiography was all that was performed being the worst case scenario. Using Compress updating just the long seam to Full RT does not change the MAWP. This should be...
Hey @IdanPV, the governing code for vessels in propane service CSA B149.2 here in Canada and it requires that all propane storage vessels have a 250PSi MAWP. so unfortunately we aren't allowed to derate and maintain it in LPG service.
Hey all, We are performing Compress code calculations in preparation for a CRN application for an LPG storage vessel in Saskatchewan Canada. The Vessel already has a CRN in Ontario as that is where it was initially constructed and installed. My issue is that it was sold and moved into...
Hey all, this is a DOT spec tank but we are operating/inspecting in Alberta Canada so we are following B620-2020 rules regarding inspection and repairs etc. and in the case of all dangerous goods piping it tells us to just follow B31.3. Also yes we do meet all the requirements of section C.
Hey all, I'm currently in the process of design a piping specification for use on C02 transport trailers. the minimum working temperature needs to be -57°c (below the triple point) and max temp of 38°C. with a MAWP of 450PSI. We would like to use A106B pipe and A-105N fittings, knowing that we...
