This section also limits design pressure to 125psig for pipe sizes 12 IPS and 100psig for pipe sizes >12 IPS. NOTES: The above weights are calculated per PPI TR-7, using a density of 0.960 gm/cc. FOR GAS DISTRIBUTION

HIGH DENSITY POLYETHYLENE (HDPE) PIPE PART 1

HDPE pipe holds pressure by developing stress in its walls, thus the pipe will increase slightly in diameter when under high pressures. The procedure for pressure testing HDPE main should take in account the expansion of the HDPE main. The recommended procedure is to:a.
