Applicability of Codes and Standards to Piping

ASME/ANSI B31.3 is a Process Piping Code that applies to metallic, non-metallic lined and non-metallic piping systems handling various fluids. I would suggest you purchase a copy of this Standard for review. This is a fairly comprehensive standard, with specific guidance on applicability to plant process piping systems based on operating pressure, temperature and fluid.

dhox,

Don't you find it interesting that you have been assigned to perform work on chemical plant piping but do not have access to the ASME B31.3 piping code ...??

Let me guess,..... you work for an MBA who has proclaimed that "all technical staff should purchase thier own tools, including codes and standards"

His undergraduate degree is probably in accounting or finance and he is somehow related to the owners of the firm.

The 2002 edition is available from

we do have the standard now. it was quite odd to us that we did not have the standard. i think that the reason we didn't already have it is because we are under the jurisdiction of the NRC and they don't use ASME B31.3 as a required standard.

What's the "NRC" and what do they use instead of 31.3?

Nuclear Regulator Committee. I believe they have their own set of standards. If they approve of the installation, the onus is on them. I'm not sure because I have was not involved in the installation of our first plant. The one currently being designed is a DOE facility/project.

Piping to the NRC regs refers to the ASME B&PVC which also defaults to 31.1 and 31.3 on specific issues.
I can see how you did the original work without knowing the boundaries and applicable codes (Nuc over rides), but not without the reference tools.
