Field hydro test pressure of boiler assembly as per ASME Section I
Field hydro test pressure of boiler assembly as per ASME Section I
(OP)
Hi
As per ASME, individual components of boilers (SH,RH,Eco) are to be hydrotested at shop, at 1.5 times maximum allowable working pressure. All these 3 sections are designed for different pressures, based on pressure drop, head etc. For example, eco may be designed at 100 bar, SH may be at 95 bar etc. Each component will be hydrotested at shop as per ASME PG 99.
At what pressure, the boiler has to be hydrotested after total assembly at site?
This is a section I construction boiler.

The case you have mentioned is for once through boilers (drum less type). I was asking for subcritical drum type boiler.
I guess, it is 1.5 times drum pressure.
But as i know, maximum pressure will be coming in economiser circuit. So whether it has to be 1.5xeconomiser pressure ?
