Hello everyone,
My client is pretending to expand steam at 200 bar and 370 ºC up to 56 bar and 270 ºC which means that this steam goes from nearly saturated to fully biphasic. He thinks it can be done by a valve and after that separate steam from water.
However, I have always though that...
Good morning,
I have a installation which needs Nitrogen. I am using Nitrogen gas cylinders. The issue is that I have simulated the expansion proccess in a very simple way:
- Inlet line with fixed flow and pressure (around 200 bar)
- Pressure reducer valve
- Outlet line. Same flow (mass) and...
Good afternoon,
I am designing a pressure filter with a design pressure of 6 bar. There are 24 of them working in parallel, all outlets end in a common collector and this collector goes to some cartridge filters. This main header has not any valve.
However, this header has a bypass that in...
Hi everyone,
I am doing some calculations with piping ASTM SA312 TP321. I am having some troubles deciding which is the maximum allowable stress since ASME 31.1 allows 2 different values for 750 ºK: 12.7 and 17.2 ksi. The diffrence between them is that for the value 17.2 the following note...
Hi everyone!
Recently I have been involved in the design of a hydraulic circuit with heavy pumps. The prblem came when we studied the shut off case. In case of shut off the piping were not able to stand the pressure so we decided to install PSV valves. Normally, this is not a problem, but in...
I have a C2A3A235261 flowserve mechanical seal: Category 2--Arrangement 3--Type A. Do someone know the temperature limit for this kind of seals? I have done some research through the internet and apparently Category 2 can work up to 400 ºC (750 ºF). However when it is type A... the temperature...
