FIELD: machine building.
SUBSTANCE: segments are connected in directions along circumference and pipe length, in order to assemble a recovering pipe inside the existing pipe. Multiple nuts are fixed to segments along the direction of segment circumference. There is a fastening element, having a threaded part, which is screwed into the nut in order to attach the first segment to the second segment, to which a nut is fixed, thus connecting the first and second segments in direction of the pipe length. Position of the nut in the first segment is displaced, with a view in direction along the circumference, from the position of the nut of the second segment. Layout of fastening elements and nuts is made in staggered order, with a general view.
EFFECT: possibility to make strength of segments connection identical in direction of pipe length.
