FIELD: construction.

SUBSTANCE: invention relates to construction and is used in repair of fiberglass pipelines. Method of repair of fiberglass pipeline includes removal of defective area and installation of repair kit elements instead of defective area with fastening and sealing on ends of pipeline adjacent to remote defective area. At that, at least one end of repaired fiberglass pipe is used to grind cone whereon threaded insert is installed with preliminary application of thermosetting adhesive composition on inner surface of threaded insert and/or on outer surface of pipe cone. Then, repair set element with two opposite threads at ends is introduced into raised sections of repaired pipes. Said element when lowering pipeline is rotated, providing its gradual screwing with elements having left internal thread and right internal thread.
