METHOD FOR CONNECTING OF PIPELINE ENCLOSURE OUT OF POLYMER COMPOSITE MATERIAL WITH METAL TIP Russian patent published in 2014 - IPC F16L9/00 

FIELD: machine building.

SUBSTANCE: method of pipeline connecting is suggested, the pipeline has enclosure out of polymer composite material and metal tip; the method means installation on the metal tip of the pipeline with fixing member obtained by winding in form of a ring with 50% overlapping by tape out of polymer material with further polymerisation. Between the metal tip and the pipeline enclosure there is adhesion layer out of the material similar to the binding material of the enclosure. The adhesion layer thickness is selected from ratio (10≤b≤12) mcm, ring of the fixing member is made by tape out of the polymer material with double-side coating based on the material similar to the material of the pipeline enclosure making winding to the specified number of layers through length equal or by 2 times exceeding the length of the connected surfaces of the metal tip and the pipeline enclosure, and polymerisation is performed to melting temperature of the binding material.

EFFECT: reliable tightness of connection between the metal tip and pipeline enclosure out of polymer composite material.
