5/11/2012· Many websites give the rule that HDPE pipe can handle a scratch as deep as 10% of the wall thickness without reducing the pressure rating of the pipe. One source for this is AWWA M-55 [''Manual for the Design and Installation of Polyethylene Pipe'' from the China Water Works Association], which apparently says "pipe with gouges or cuts in excess of 10 percent of the product …

Removing 0.7 mm from the pipe surfaceincrease failure times to 2000 h to HDPE pipe 100 mm diameter h. Outside weld beads and outside pipe surface clearly interact to lower the time to failure in accelerated creep tensile tests. Weld bead removal and scraping of outside pipe surface
Comprehensive stocks of seamless and welded pipe includes 6 NB (1⁄8") to 600 NB (16") in SCH 10S and SCH 40S. Seamless pipe is also available ex-stock in heavier schedules such as SCH 80S, SCH 160 and XXS. Larger sizes of both seamless and welded
PE Pipe Peeler prepares the outside diameter of polyethylene pipe for electrofusion by removing the oxidized layer and contaminates. PE Pipe Peeler can be used on the edge of the pipe or anywhere along the pipe with sufficient clearance for turning the tool around the pipe.

Around 1:30, a small bead will begin to appear from the pipe at the point of contact with the hot plate. NOTE: This step must be done quickly to ensure efficiency and quality. At 2:00, unlock the Pit Bull, remove the hot plate, and slide the pipes/ pipe and fitting together and press so that one bead rolls onto the pipe from each side, reseling a pair of lips.
