| description | The presented study discusses the structures used for restoring the bearing capacity of the main pipeline sections in case of the corrosion damage. It is shown that a welded crimping socket the most frequently used in repair can efficiently reduce stress in the pipe walls only in close joints. To increase the repair structure efficiency, it is proposed to place an elastic layer between a pipe and a socket which can fill the space and transfer a part of load from the pipe to the socket. The elastic layer material must be, first, soft enough to completely fill a gap between the pipe and the socket considering the pipe surface irregularity. Secondly, the material must be characterized by a sufficiently large elastic modulus (in the range of 1000 MPa |
