发明名称 Pipe lining
摘要 A lining method for a host pipe (10) including lubrication of the host pipe prior to insertion of a thermoplastic liner (11) using tight fit techniques. After allowing the inserted liner to relax, the liner is partially pulled from within the host pipe using puller (20) and clamped with an internal clamp (30) to allow fitting of a special flange (40) to the liner (11) by butt fusion, for example. Threafter the liner is allowed to revert so as to abut a flange (12) fitted to the host pipe (10). The technique is repeated at the other pipe end.
