Compressor tank - drainage considerations
Compressor tank - drainage considerations
(OP)
Hi guys - first time poster - so take it easy on me!
Are there any specific guidelines or standards that should be followed when designing the drainage system for a compressed air tank?
Logically, the drain system should be designed in such a way to withstanded the nominal working pressure of the vessel in the event of a drain blockage.
While that premise is logical, where might I find published information that might provide additiaonl guidance, specifically on the drainage requirements for a compressed air tank.
for info:
tank capacity: 5.5 m^3
storage medium: compressed air
nominal storage pressure: 30 bar
Any assistance is greatfully appreciated.
Thanks.

RE: Compressor tank - drainage considerations
Either a manual or automated drain valve is typically used on such a tank. Automated valves typically are actuated base on timers. Selecting the valve (and nozzle size) is more dependent on the rate of condensate generated rather that the size of the tank.

Tell us more about your location and what is upstream of the tank......

Above all, use an automatic valve - DON'T trust your operators to keep blowing down the tank regularly!
RE: Compressor tank - drainage considerations
I am after any guidlines (ASME pressure vessel codes or other.....) that discusses any considerations or criteria for the design of a drainage system.
Any assistance is appreciated.

You have to design the SYSTEM - from outlet of the compressor through its piping and check valve out to the tank to its isolation valve and relief valve through the drain valve to that final opening as a pressure system. The tank has "rules" and the relief valve has rules and the piping has rules intended to protect the nearby people from overpressure.
