PLASTICS PIPING SYSTEMS - FITTINGS, VALVES AND ANCILLARIES - DETERMINATION OF GASEOUS FLOW RATE/PRESSURE DROP RELATIONSHIPS
07-05-2015
01-01-1999
Determines a method for the flow rate/pressure drop relationship of components for plastics piping when tested using air at 25 mbar. Data obtained may be used to calculate the flow rate of such gases for a special pressure drop. Applicable to valves, mechanical fittings, tapping tees and other ancillaries that are intended to be used in polyethylene (PE) piping systems for the supply of gaseous fuels.
