Hello,
I'm tasked with design of a filter (pressure vessel) to meet a specific UL Standard, 331, and only to that standard. To my understanding, the standard covers some requirements and limitations on the construction of the filter, but not to the extent of a code, say for instance ASME BPVC Section VIII Div 1. There are specific performance or test requirements which the design will surely satisfy. For one example, UL 331 does not cover prequalified WPS or permissible or non-permissible weld joint designs (based on my very light reading of Sec VIII Div 1, that code does).
My question is, is it generally advisable to use or reference a code such as the BPVC to ensure that my design is (for lack of a better phrase) based on sound design and construction principles?
A slightly more specific point - there is an unstayed flat head head in my design. Prior to looking into the BPVC, I would have designed the head and its weld joint in a way NOT shown in Figure UG-34 (I have the 2013 copy of Sec VIII Div 1). I'm now thinking it may be best to follow an established code for certain parts of my design.
Is this something others typically do and if so, are there any other standards or codes that may be helpful in the design? I've also looked into AWS D1.1, but it's obviously less pertinent to the design of a pressure vessel when compared with the ASME BPVC.
For what it's worth as some may be curious, the filter will be constructed of SS30403 and feature welds, bolted-on components, threaded caps, will have a total volume of approximately 40-liters, and will need to be able to handle a pressure of 250 PSIG.
Thank you.
