Paton Electric Welding Institute of the National Academy of Sciences of Ukraine popup.description2 On basis of the proposed calculation algorithm and computer program executed in the 3D numerical study of the effect of incomplete fit of the tube walls and reinforcing structures (maff or band). In a random distribution of contact zones (using the Monte Carlo method) found that the length of muff (band) order of pipe diameter and the relative plane of contact more than 20% firming construction is quite a reliable in its functionality. Were developed diagrams to determine the required tension reinforcement structures for these and engineering method to control this tension by mechanical deformometer with magnetic mount to the surface of the muff (band). It is shown that such repair defects in the zone wall thinning can be done without taking the pipeline out of service, and without prejudice to the environment.
