Ring Main

A section of pipework that forms a ring around a factory. It is feed by a line from the compressor an can have drop legs and branch legs off it. Compressed air will travel in both directions around the ring main depending on where the greatest demand is. This is a good way of installing pipework as it creates significantly less pressure drop compared to a similar length branch line.
