I'm trying to establish at what pressure would an owner consider ASME B31.3 piping to be classed as "High Pressure"?
The piping is not carring a dangerous fluid.
ASME has come out with another high pressure piping code which starts at 10,000 psi. would it be logical for a well designed system operating at less than 10,000 psi not to be considered as high pressure piping?
