Polyethylene (PE) is a thermoplastic material that belongs to a group of polymers called polyolefins which is produced from the polymerization of ethylene. Polyethylene is usually first categorized by its density as indicated in the abbreviations e.g. HDPE (high density PE), MDPE (medium density PE), LDPE (low density PE) and LLDPE (linear low density PE). PE plastic pipe is manufactured by extrusion and depending upon diameter required is available in either coils or in straight lengths. Polyethylene pipe is corrosion resistant and has a long history of use as an abrasion resistant material in mining applications. It is lightweight, easy to |

install, and reduces the number of fittings needed in a system because of its flexibility. Heat fused polyethylene pipe produces a leak free joint that is as strong, if not stronger, than the pipe itself in tension and pressure applications. These joints are self-restrained,they need no thrust blocks or restraint harnesses except where the pipe attaches to a non-polyethylene system. |
