ASME Section VIII §UG-127(a)(2)1 indicates that the relieving capacity of a rupture disk used independently (that is, not on the inlet or outlet of a pressure relief valve) can be determined based on one of…
Read More »For overpressure protection systems involving pressure relief valves, the frictional losses in the inlet and outlet piping is used as a means for evaluating the installation of the pressure relief valve, particularly as a measure…
Read More »A rupture disk (RD), also known as a pressure safety disk, burst disk, bursting disk, or burst diaphragm, is a non-reclosing pressure relief device that can be used as the sole device as well as…
Read More »The API Standard 2000, 7th Edition thermal inbreathing calculation has conservative assumptions regarding the rainfall rate and fluid properties within the tank that can result in excessive venting requirements for small tanks, such as those…
Read More »The analysis for the flow of liquids through pressure relief devices in API and ASME standards is currently predicated on the fluid viscosity behavior being Newtonian; API Std 520 Part I, 8th edition (2014), explicitly…
Read More »Overpressure protection must be provided for pressurized equipment by means of pressure relief devices, which sometimes require isolation and removal for inspection or repair. It would be advantageous to have a means of isolation without…
Read More »Sudden tube ruptures in shell and tube heat exchangers operating at a high differential pressure in which the low pressure side contains an incompressible fluid and the high pressure side contains gas have been recognized…
Read More »Following the release of the most recent Fireside Chat on pressure relief critical controls, we received a question specific to critical check valves, or non-return valves (NRVs), and our thoughts on taking credit for them…
