Hi All,
I have seen and read posts that say rule of thumb is to install a thermal relief valve for every 500 liters of liquid. I have a 24 in pipeline that is 1000 ft long. Does this mean I have to install a TRV every 6 ft? That’s 167 TRVs. IMO, that seems like a lot of TRV for a straight pipe...
Hi all,
Is there a rule of thumb for the maximum pressure drop in a liquid pipeline (psi/100 ft)? I am used to sizing gas plant piping and haven’t done liquid a whole bunch.
Since liquid is an incompressible fluid, I will expect the pressure drop to not be as significant as experienced in gas...
I filled a lot of RFQ and data sheets for valve procurement and noticed that the fluid flowrate is usually NOT REQUIRED in designing shutdown valves. I find this peculiar. Does anyone know why? On the data sheet, they request for virtually all other fluid properties, but not flowrate. I am...
Hi everyone,
I am a "green" process engineer and have a couple of questions about regulator data sheets. On the data sheets that we provide for vendors to get quote, you have to put in the inlet pressure and pressure drop across the valve. I have included a diagram.
If a BPV is set at 50 psig...
