Pressure Ratings are calculated using 0.63 design factor for HDS at 73°F as listed in PPI TR-4 for PE 4710 materials. Temperature, chemical and environmental use considerations may require use of additional design factors. Pipe weights are calculated in accordance with PPI-7 TR-7.
Section 1 covers Design based on Working Pressure Requirements. Procedures are included for dealing with the effects of temperature, surge pressures, and the nature of the fluid being conveyed, on the sustained pressure capacity of the PE pipe. Section 2 deals with the hydraulic design of PE piping. It covers
Based on the international standard HDPE pipes are available in all pressure classes, with diameters range from 90mm up to 500mm and it is necessary for lengths of pipes to be supplied by agreement between purchaser & manufacturer.
HDPE Pipe: The pressure class of a polyethylene pipe includes an allowance for surge pressures. The allowance for recurring surge pressures (regular valve and pump operation) is 50% of the pressure class. For occasional surge pressures (unanticipated system failures), the allowance is 100% the pressure class. PVC Pipe:
31 maj 2023 · Table below provides dimensions of HDPE pipes for PE100 material of rating PN25, SDR 7.4 or S3.2. The following section provides a brief background of the various definitions used and the applicable calculations while referring to PE pipes.
