Pipe spec/class naming conventions

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.

RE: Pipe spec/class naming conventions

What ever you do remember
"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.

Hi,

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

Actually I've seen a leading "B" used for 150# more often and "A" used for Class 125.

PennPiper, Frank, Nozzle Twister: thanks fellas.  I'll have a root around and see what I can come up with.

RE: Pipe spec/class naming conventions

NozzleTwister,

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?

Ashereng,

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

Nozzle,

Yup. Agree.

Like I said, it varies with industry and geography.
