Is Hot water pump a pressure vessel/tank?
Is Hot water pump a pressure vessel/tank?
(OP)
Hi
We received this morning a hot water pump at the shop, pumping to pressure over 300 psi. It is a 3 inches pump in Cast iron. We found a crack in the casing.
Is it included in ASME pressure vessel Code ? Do I need to use a qualified procedure, welder, etc..
I just want to know if I can repair it or not with on of our welder... Where can I find this information.
Thanks

or components of rotating or reciprocating mechanical
devices, such as pumps, compressors, turbines, generators,
engines, and hydraulic or pneumatic cylinders where
the primary design considerations and /or stresses are
derived from the functional requirements of the device;
