REPAIR METHOD OF PIPELINES AND TECHNOLOGICAL COMPLEX FOR ITS IMPLEMENTATION Russian patent published in 2010 - IPC F16L55/165 F16L55/00 F16L58/10 

FIELD: machine building.

SUBSTANCE: method includes introduction of plastic pipe into repaired steel pipe. In the beginning of pipeline it is installed block of continuous manufacturing of pipe. Front part of manufactured plastic pipe is connected by rope with tractive member, installed in end point of repaired pipe. Then it starts process of continuous manufacturing of plastic pipe with its simultaneous feeding into repaired pipe and filling of pace between pipes by substance with adjourned time of polymerisation. Polymerisation time is assigned more than time for passing of plastic pipe in repaired pipe. Technological complex for method implementation contains block of continuous manufacturing of plastic pipe, implemented in the form of device for one-layered or multilayer extrusion and/or casting and/or facing of plastic. In the end of repaired steel pipe it is installed tractive member with flexible tractive member, free end of which is connected to front part of plastic pipe.

EFFECT: reduction of repair time, reduction of materials consumption, increasing of extension of repaired pipeline.
