Apart from companies'/owners' standards, is their any technical reason (valve cracking, mechanical integrity ..... etc.) or any obligatory code or standard that prohibits the use of control valve rating 150# for raised face flanged control valves (Globe Style) smaller than 2 inches in oil and...
I am purchasing a 600# 2 inch flanged pressure transmitter. The piping is 600# carbon steel. There is a process condition that could last for days with a pressure of 1250 psig and a temperature of 200 F. According to the ASME tables, a 600# carbon steel flange maximum pressure is 1350 psi at...

I want to use pressure transmitters and differential pressure level transmitters with diaphragm seal on the bottom of a vacuum tower. The pressure is 1.5 psia and the temperature is 400 C. I saw ultratherm 805, and as per the curve provided in the catalog, at 1.5 psia the maximum temperature...
I have to use a pressure transmitter with a flanged (Raised Face rating 600#) diaphragm seal on a the on the outlet of a well. The material engineer specified that the wetted parts shall be Hastelloy-C, so i chose the diaphragm material to be hastelloy-C. What should the diaphragm seal flange...

Is there a technical reason why most companies specify a minimum 300 rating for control valves below certain sizes ?
Is there any code that prohibits the use of 150 rating for 1 inch control valves ?

I have a problem in a project i am working in now (still in the engineering phase).
The purge line for the flare is from the discharge of a compressor. so the design was to place a restriction orifice to drop the pressure from 1500 psi to 20 psi. I calculated the bore diameter of the RO and it...
