Abstract
Increasing volumes of repair of defective areas require the development and application of more economical and less time-consuming ways to restore their load-bearing capacity, eliminating the cutting of pipes, and in certain situations, and stop the pumping of gas. In recent years, the emphasis in the world practice of repair methods has shifted towards the wider use of coupling technologies, which allow to exclude cuttings of pipe coils of pipe plates with defects. In a number of cases, repair using couplings is a non-alternative method, for example, in case of gas leaks from the cavity and the pipeline or as a temporary means when it is impossible to stop the pumping of the product.
