METHOD FOR REPAIRING FIBERGLASS PIPES AND A REPAIR KIT FOR ITS IMPLEMENTATION Russian patent published in 2022 - IPC F16L55/16 F16L55/18 F16L47/10 

FIELD: pipeline transport.

SUBSTANCE: invention relates to the field of pipeline transport and can be used in the construction and repair of pipelines made of fiberglass materials. A method for repairing fiberglass pipes is proposed, including the removal of a defective section of the pipe and the installation of a repair kit 6 instead of the defective section of the pipe with fixing and sealing at the ends of the pipeline 1. After removing the defective area at the ends of the pipeline 1, longitudinal cuts 5 are made, a repair kit 6 is installed, containing a corrosion-resistant repair sleeve 7 with annular protrusions 8 at the ends, while on the outer surface on both sides it is equipped with annular pushers 9 with conical outer surfaces 10 and sealing rings 11, with the possibility of power movement of the annular pushers 9 in the axial direction and pressing the sealing rings 11 to the annular protrusions 8 of the repair sleeve 7. The fixing and sealing of the repair kit 6 at the ends of the pipeline 1 is carried out until the longitudinal cuts 5 close. A repair kit is also proposed for implementation the described method for repairing a fiberglass pipeline.

EFFECT: invention improves manufacturability and efficiency by providing mechanical strength of the repair joint in the axial direction, tightness, corrosion resistance, allows you to quickly eliminate the leakage of the pumped liquid, and also optimize the cost of repair work by reducing the amount of earthwork during repair.
