摘要: A water supply pipe has a tubular liner of a polyolefin elastomer/plastomer installed therein. To install it, a messenger pig is attached to a line that pulls the liner through the pipe. The liner is produced by extrusion and die drawing during extrusion.

摘要: Device for use in rehabilitation of water supply pipes includes a tubular liner (10) which is deployed through a pipe (11) for example by a line attached to a messenger pig which is propelled through the pipe. The liner (10) has a multi-lobed pleated cross-section, and is of a polyolefin elastomer material, e,g, a substantially linear ethylene inter-polymer. The liner is extruded and die drawn during extrusion to produce a reduced diameter highly oriented structure.
