FIELD: pipeline manufacturing.
SUBSTANCE: method comprises molding funnel simultaneously with molding the load-bearing layer of the pipe. The end of the pipe is conical and is made of the fiber basalt glass material. The pipe moves in the threaded mold in a partially solidified or soft condition. The binder is supplied to the space between the threaded mold and conical part by means of working the end with the threaded mold.
EFFECT: enhanced strength and reliability.
