Chill water piping and B31.2
Chill water piping and B31.2
(OP)
I am currently fabricating 4" sch 40 carbon steel pipe for an HVAC unit to be located off-shore. My client is holding me to B31.3 and APR RP-14E on fitup,welding, installation and testing since this will be installed off-shore in a refinery/production environment. This piping will have no more than 20 feet of material with 35psi of chilled water flowing at about 45*F. Also, specifically, under code I will have to test this system at 350psi which is way above many of the components of the chiller and air handler units.
In my opinion the "spirit" of B31.3 and RP-14E is not intended to apply to this type of piping installation, although it is installed in a petroleum environment. I could use a clear definition of "Process Piping".
I have not been able to find any reference in either code that will allow me to present a argument against meeting code with this application. Any ideas?

Are you really that worried about the quality of the welding? If so, I'm not sure I'd want to be the client...

An approach you can take is to ask that it be classified as Category D Fluid Service, in which case the requirements are less stringent (e.g. no radiographic examination). The subject system can be classified Category D, based on how you described it.
