Temperature considerations for stainless steel relief valve application

Jun. 24, 2018

The process of selecting or evaluating correct set pressure for stainless steel relief valve application is relatively straightforward. The set pressure of the stainless steel relief valve is compared to the pressure vessel maximum allowable working pressure (MAWP). The correct set pressure can be determined by using ASME Code rules and the general principle that at least one valve must be set at or below the MAWP.

The Code does not thoroughly explain temperature considerations, and application concerns related to temperature are just as important as proper selection of the correct set pressure.

One concern is selecting correct material for stainless steel relief valve construction. For pressure vessels, service temperature is considered part of the vessel design conditions, and the maximum temperature is used to select allowable stress limits for the chosen vessel material.

As a relief valve parts factory, we can provide relief valve parts, stainless steel relief valve with high quality and competitive price.
