Is generally referred to the piping on the discharge side of a compressor.
The diameter of the compressor discharge pipe should not normally be smaller than the compressor outlet connection and should be arranged with flanged fittings or unions to permit easy access to the compressor and components at any time.
The possibility of vibration should be considered. The compressor discharge pipe will attain a high temperature, and precautions must be taken to prevent this being a source of danger.
A provision should be made to install a flow meter for monitoring of the output flow.
