Abstract

In pneumatic system, compressed air discharged from compressor is supplied to the terminal equipment through main supply piping. However, this pressure transition process involves loss of compressed air energy due to pressure loss and air leakage loss. This standard specifies the energy condition monitoring method, the maintenance procedures, methods of identifying cause and the optimal pipe size selection method for main supply piping in pneumatic systems.
