Pipe spec/class naming conventions
Pipe spec/class naming conventions
(OP)
Apologies if this is in the wrong place, but here goes anyway...
Is there a generally accepted naming convention for pipe specs or pipe classes? I can't find a standard which covers this. I've been tasked to create a number of pipe specs or pipe classes that we can use on future small (truck mounted skid type) projects. I could always invent a system but don't want to 're-invent the wheel' when I don't have to.

"KISS" (Keep It Simple Stupid)
I have seen cases of pipe spec/clasifications where they were made far too complex because the originator wanted them to be "smart" codes.
The best ones I ever worked with were simple codes and only identified the basics.
i.e.: 3 position, 1st position is flange rating, 2nd position is material and 3rd position is corrosion allowance.
Example;
AA1 = 150# Carbon Steel 1/16 C.A.
CA1 = 300# Carbon Steel 1/16 C.A.
etc.

The is a Process Industries Practices (PIP) number PNSM0001 which can be used as guideline for naming the piping line classes.
Hope it helps,

RE: Pipe spec/class naming conventions
In my industry, A=150# usually, B=300#, C=600# ...
I have never used 125# ANSI, and in the upstream side, we are seeing consolidation of starting at 600# and going up (nothing under 600#).
I guess it varies by industry and geography, like everything else?

While it is not as widely used now as it once was, 125# systems are common in many refineries for low pressure utility services.

Yup. Agree.
Like I said, it varies with industry and geography.
