THERMOMECHANICAL COMPLEX OF PIPELINE INNER COMPOSITE COAT Russian patent published in 2013 - IPC F16L58/10 F16L101/16 B05C7/08 B08B9/49 

FIELD: machine building.

SUBSTANCE: thermomechanical complex consists of articulated self-propelled cleaning module, diagnostics module, turbine expander and self-propelled module of coat application. Expander turbine is driven by pipeline gas flow to run the shafts of electric generators. Electric power produced by said generators is used to drive the complex inside pipeline, clean pipeline inner surface, monitor its state, separate polymer particles from gas flow, compact polymer particles, heat them and convert into viscoelastic bulk and to apply two layers of said bulk together with several layers of reinforcer fibres. Self-propelled modules are driven by barrel-like mills tightly pressed against pipeline inner surface. Motors revolve said mills in different direction along different spirals via misaligned gearboxes, change-gear trains, reduction gearboxes and drive shafts.

EFFECT: reconditioning pipelines without interrupting its operation.
