High Temperature Water Boiler Definition
High Temperature Water Boiler Definition
(OP)
We have electrically heated devices that produce hot water with a temperature on the order of 500F and pressure on the order of 1000 psig.
The State Of California doesn't give a great definition of "boiler" but some states specifically include hot water in the definition. Creating steam is not a requirement.
The questions are these: from the operating conditions are these devices "High Temperature Water Boilers"? Second: does ASME Section I apply? FWIW, the "boilers" are 1" nominal 316 SS tubing with cal rod heaters. Under ASME Section VIII they might be exempt based on pipe size.
My unqualified opinion is that these are Section I boilers but I am looking for more qualified information.
Thanks!

It can only be exempt from annual inspection if it was built to ASME specifications - if any apply.

a "S" stamp holder to rate this boiler and the state may issue a "State Special". You might also have to remove it from service. But maybe not if you approach this properly.
