METHOD OF MAGNETOCONDUCTIVE CASING REPAIR Russian patent published in 2013 - IPC F16L55/168 

FIELD: machine building.

SUBSTANCE: method of magnetoconductive casing repair implies forming of compaction on damaged area made from ferromagnetic adhesive composition applying this composition on a patch piece, placement of the patch piece with this composition on casing damaged area, action on the composition through the patch piece by continuous magnetic field generated by external source of magnetic field, and removal of external source of magnetic field after composition curing. As a patch piece non-magnetoconductive layered elastic flexible plate is used, one of outer layers of which is made from elastic mechanically strong material, non-permeable for adhesive composition, and the other outer layer is made from flexible material. Adhesive composition is applied on non-permeable for it outer layer of plate.

EFFECT: enlarging area of application, reducing labour intensity and time consumption for repair, improving reliability and quality of repaired casing sealing, improving efficiency of magnets use.
