Abstract

Background. Getting high efficiency of enhancing pipeline of small and medium diameter using well-bond joints is complicated, because of the low modulus of elasticity compounds used to form the under-join layer.

Objective. Development of the strength increasing technique of the high pressure pipelines parts using the well-bond joints is the aim of this study.

Methods. Strength increasing technique of a working pipeline with the help of well-bond joints was used.

Results. The strength increasing technique of the high pressure pipelines parts using the well-bond joints, which are filled with molten metal with a high modulus of elasticity, is offered. The operations of forming the under-joint layer with parameters providing achievement of maximum tension decrease level in strengthened pipe providing and equal load distribution between a side of a pipe part under repair and joint covering are considered.

Conclusions. The offered technique gives an opportunity to increase efficiency of strengthening the medium and small pipes diameter pipes.
