But I'm affraid that using B31.1 in this case is not very suitable as the scope I refer to below: 100.1.2 Power piping systems as covered by this Code apply to all piping and their component parts except as excluded in para. 100.1.3. They include but are not limited to steam, water, oil, gas, and air services. "(A) This Code covers boiler external piping as defined below for power boilers and high temperature, high pressurewater boilers in which: steam or vapor is generated at a pressure of more than 15 psig [100 kPa (gage)]; and high temperature water is generated at pressures exceeding 160 psig [1103 kPa (gage)] and/or temperatures exceeding 250°F (120°C)." I hope I may receive the advice in more detail. Thank you very much.
