This Appraisal is for a range of Poliplex® Polyethylene Series 1 PE112 plain wall pipes manufactured in sizes from DN 16 to DN 2000 with pressure classifications from PN4 to PN32 (depending on size).
The higher strength PE112 compound allows pipes with the same pressure classification to be manufactured with a reduced wall thickness, when compared to PE100, thereby providing increased bore size and improved flows. PE112 pipes also exhibit improved resistance to slow crack growth which is considered particularly advantageous for pipe rehabilitation techniques including die reduction lining, pipe bursting, directional drilling and slip lining.
Pipes up to DN 140 can be supplied in coil lengths up to 100m depending on size and pressure classification. Larger sizes are typically available in 12 m lengths, although longer lengths can be supplied by arrangement.
Poliplex PE112 pipes are available as black with blue, purple or cream stripes for drinking water, non-drinking water and pressure sewer applications respectively.
