METHOD OF RECOVERING LOADING CAPABILITY OF DEFECTED PIPELINE SECTION Russian patent published in 2006 - IPC F16L55/17 

Abstract RU 2270954 C2

FIELD: pipeline transport.

SUBSTANCE: method comprises grinding and filling the defect of the section to be repaired with metal, e.g. copper, covering the repairing zone with lining, and pressing the lining to the surface of the pipeline by means of yoke. To fill the defect with metal, the defect zone is provided with cruicible having sectional pad; the cruicible is filled with thermite composition, e.g. copper composition, and the composition is initiated. The defect is filled with the melt of metal that is generated in combustion of thermite compound with simultaneous formation of melted lining on the pipeline. The height of the lining is equal or less than the thickness of the pipeline wall.

EFFECT: simplified method.
