ASME B31.3 Process Piping Code
ASME B31.3 Process Piping Code
(OP)
The above is a code that our products haven't been asked to meet before, but we have a customer who wants to specify it. Without going out to buy it and read it front to back, can anyone give a very brief synopsis of what kinds of things it requires?
Is it, for example, a code that specifies Stainless Steel Piping, a particular pipe schedule, or types of connection fittings that may be used?
Is it something that would apply to potable water systems, or only in closed loop piping such as boiler systems, or process heating?
Thanks for any general clues as to what's in ASME B31.3

RE: ASME B31.3 Process Piping Code
If your customer is requesting fabrication of their piping to this Standard, I would strongly suggest you purchase it, review it and understand what is required. There is not enough space in this forum to provide a decent summary.
RE: ASME B31.3 Process Piping Code
Welding
Materials
Fittings and other components
Pressure Tests
Stress Analysis and Support
Gaskets
Thermal Expansion
Pressure Relief Piping
There is also 31.1 which would deal more with the boiler and water systems you were talking about. They are similar in scope just specific for the fluid application.
RE: ASME B31.3 Process Piping Code
Can you tell me if B31.3 is a spec that would prohibit using these types of components for carrying potable water at pressures below 125 PSI?
We get customers that frequently ask for codes that don't even bear a passing relation to the product we provide, so it's hard to justify going out and buying every one we're asked about, if we're never going to build to it.
Again, thanks for any clues you can give as to the contents.

This should give you some more details of what it is all about....
