How to determine the max. end load for safety relief valves?

jhkim · Jul 3, 2003

Can anyone help me on the max. end load of the safety relief valves connected with the piping? How to calculate or get the maximum resultant axial force and end moment permitted to be transmitted by the piping to the valve?
Valve body material is A216 gr. wcb and set pressure is 150 psi. Inlet size is 3/4 inch, outlet size is 1 inch.

The Crosby Engineering Handbook, CHapter 7, page 12, give reaction force calculations.

Go to Dresser Site and download SRV-1 in Adobe PDF Format. On Page TI.5 (Page 298 of 350) there is a reaction calculation chart.

Thaks for your help!

I think that the reaction force for safety valve is so different with the allowable end load(force and moment).

I want to know how to calculate the allowable piping end load which is applied the safety valve.

Another help, please!
