Although long-time maintenance and pipefitter personnel here do not recall using it, one of two carbon steel and a single galvanized steel company piping specifications use Class 125 pipe.

QUESTIONS
Do you know of any out-of-the-box CADWorx spec files that include Class 125?

Is it necessarily difficult to set up this Class 125 based on other classes?

Do you have a Class 125 spec that you could share?
