METHOD TO REPAIR PIPELINE, COMPLEX OF EQUIPMENT FOR REALISATION OF METHOD AND ITS DEVICES Russian patent published in 2012 - IPC F16L58/02 F16L59/14 

FIELD: machine building.

SUBSTANCE: method to repair pipes dismantled in process of pipeline repair and accepted suitable for repeated use, is carried out on a route under basic conditions using a complex of equipment for repair of pipes, in connected mobile modules of which pipes are cleaned from old insulation, the external surface of the pipes is prepared for application of a coating, the external surface of the pipes is insulated by application of a protective coating, while heating the external surface of pipes to speed up the process of protective coating polymerisation. Pipes are moved to the place of storage, at the same time works are carried out in a general flow, for this purpose each pipe is based on two trolleys. Depending on the nature of technological operations, each pipe is given a rotary movement using reciprocal motion of trolleys along a rail track, besides, ends of pipes at the length of at least 150 mm are protected against application of a coating.

EFFECT: method expands the arsenal of technical facilities, increases efficiency of a process for coating application under route conditions onto pipes, also of large diametres due to automation and synchronisation of efficiency of processes for preparation of external pipe surfaces and application of an insulating coating onto them.
