Hi this is a relatively similar subject to a query that I have, @SnTMan perhaps you can add your thoughts? I have a vendor that has completed prelim nozzle calcs for a vessel I am procuring, and we have some 'heavy bore', or as I call them self-reinforced, large bore nozzles for access manways...
Hello all,
I'm having some problems designing a manway cover modification, where the client requires a 6" nozzle (c/w instrument) adding to an existing manway cover. Design code is PD5500, and most other threads cover this same activity in ASME code only. The main problem seems to be caused by...
@r6155 Yes I also saw that comment - but I took a corner joint to cover set on nozzles and not set-through nozzles, where joined with a full pen weld. Mandatory appx 3 suggests otherwise, and that a corner joint is defined as follows;
(c) corner joint: a joint between 2 members located in...
Although I can understand your point on nozzle joint calculation, how do we mitigate this in design software, where we must select the RT level at the package level, should we still be able to select RT-1 even with nozzles that have not been volumetrically inspected? The only calcs that I can...
DEP 31.22.00.31 lists 100% UT or RT for Category 1 vessels, with a note to indicate that this only applies to ASME VIII Div 1 UW-16.1 F-1 to F-4, or ASME VIII Div 2 table 4.2.13, otherwise no volumetric inspection is required (PT/MT only). This feels like it could lead fabricators to offer...
