FIELD: machine building.SUBSTANCE: according to the invention, segments are connected in circumferential directions and throughout the length of the pipe so that the restoring pipe can be assembled inside the existing pipe. A lot of nuts are attached to the segments along the circumferential direction of the segments. The invention provides for a fastener having a threaded part, which is screwed into the nut so that the first segment can be attached to the second segment, to which a nut is attached so that the first and the second segments are connected in the direction of the pipe length. Position of the nut in the first segment is displaced if to look in the circumferential direction from position of the nut of the second segment. Layout of fasteners and nuts is performed in a staggered order if to look as a whole.EFFECT: possibility of implementing similar strength of connection of segments in direction of the pipe length.8 cl, 23 dwg |
