Compressor Delivery Line

By 4 May 2018

Pressure drop in the discharge line does not materially affect the compressor efficiency, so the gas velocity can be 20 to 25 m/s. Pressure pulsations on the other hand can cause a considerable increase in compressor power as well as damage to the piping and valves. There are two ways of dealing with the problem of delivery line pulsations: tuning the pipe length between compressor delivery valve and the after-cooler; and inserting a pulsation damper in the form of a small air receiver.
