СПОСОБ РЕМОНТА УЧАСТКА ДЕЙСТВУЮЩЕГО ТРУБОПРОВОДА СО СКВОЗНЫМ ДЕФЕКТОМ

摘要

A method consists in that a section of pipeline with through defect is repaired without termination of gas supply. To the seam through defect one installs gasket, this is pressed with band by means of pins. At two sides of the bandage one installs pairs of rings that are fixed to the pipeline and to the band. On each pair of rings additional rings are installed, on those muff is installed. Under-clutch space is filled with self-hardening mass. The method makes it possible to repair safely and to reinforce welded seams with through defects.
