We have a client who wants us to provide a water hammer arrestor for their process which apparently contains 64,000 ppm chlorides. Pressure is 50 psig at ambient temperature. They want to use CS with an internal coating to keep cost down. We normally use ScotchKote 134 for internal coating but...
I have included a screen capture of a threaded end cap for an ASME Sec 8 Div 1 pressure vessel that the company I work for has manufactured for a very long time. Recently we have been questioned on the wall thickness of the shell at the threads. I have looked at UG-31 but this seems to apply to...
David,
Thanks for your reply. In your first equation did you mean MW instead of SG? I know that SG is just a ratio of MW's but is this a valid substitution? I have the P-H Diagram for Propylene from the GPSA data book so I can get the density for a given T&P from it but I dont know if that...
I am trying to verify the actual volumetric flow rate in a test rig we have setup. The unit is a waste gas combustion device used to burn vapors from oil storage tank batteries. The test rig is flowing C3H6 (Propylene) at 10 oz/sq in, approx. 60 deg F, and at a rate that is supposed to be around...
Hello,
Looking for recommendations for an imperial PD type gas meters that can be used with Propylene gas (C3H6). The issue is the seals/o-rings, typical std construction uses Buna-N which is fine for Methane, Propane, etc... but it doesn't like Propylene. I have investigated Dresser Roots...
I am looking for some data on a phenomenon that occurs in carbon dioxide dehydration. At certain combinations of temperature and pressure the glycol becomes very ineffective in its capacity to absorb water. I am talking about temps within the safe range of reconcentration, not above the...
