Abstract

FIELD: mechanics, pipelines.

SUBSTANCE: invention relates to pipeline transportation and can be used in repair of pipelines. The pipe sleeve surface intended for radial gaps of welding joints furnished with an axial stop symmetric about two equidistant sections of glass fabric. The sleeves with opposed tapered ledges and circular stops arranged there behind allow arrangement of glass fabric sections along the circular perimeter. The tapered sections, the most distant from the stop, are furnished with annular collars arranged on the sleeve outer surface and intended for axial movement of self-hardening paste inside end face section of pipeline being jointed together. The glass fabric surface accommodate half-rings and repair sleeve assembly.

Description

The invention relates to products with which repairs of pipe ruptures and / or pipe crossings, bends are carried out, which reduces the dynamics of losses of liquid transported through pipelines and contributes to the environmental protection of the natural shelf.

To the analogue of the new technical solution should include patent No. 2283739 - “Welding unit of the pipeline” in 2005.

The disadvantages of the analogue include the low adaptability of the prefabricated assembly of the tube sleeve, which is characteristic in that when repairing pipelines, the entire mass of suitable pipeline must be moved. The new assembly sleeve of the repair sleeve does not necessitate axial movement of the opposed pipelines, since the faulty place of the pipeline is cut out and removed, and the free axial space is filled with a similar diameter repair kit in the form of the assembly of the repair pipe sleeve and welded.

The objective of the new technical solution is to increase the productivity and technological capabilities associated with the repair of gust places rude.

The task is achieved in that the assembly of the repair pipe sleeve, consisting of a welded joint of two pipes of equal diameter, characterized in that the assembly of the repair pipe sleeve is located relative to the pipe sleeve with an axial stop symmetrically located on its surface, relative to the axial stop on the surface of the pipe the bushings are placed two symmetrically equidistant sections of the fiberglass with respect to the axial stop, two sections coaxially and over the located bushings are displaced along the axis with overlapping total displaced pipe ends along the outer surface of the sleeve, the sleeve is made with opposed conical protrusions with an arrangement of ring stops behind them, arranged to accommodate sections of fiberglass along the annular perimeter, the outermost conical sections along the outer surface of the bushings are provided with ring cuffs intended for axial the movement of self-hardening mastic inside the sections of the ends of the connected pipelines, along the length L of the repair section is coaxially located fiber bushings are placed around the circumference of the fiberglass fabric, half rings are installed on the surface of the fiberglass, equal in diameter and thickness to the pipelines (6 and 7), designed for welding between themselves in axial and radial directions relative to the axial stop, interacting with the trapezoidal groove about the axis, the assembly unit of the repair pipe bushings, designed for education from the ends, as well as along the radial sections of the half rings of the weld sleeves, designed to form a monolithic connection of two pipes of wires with a prefabricated assembly of a repair tube sleeve equipped with equidistant stops necessary for matching the length of half rings when forming radial clearances of welds.

The drawing shows a profile, combined with sections of the type of pipe connection.

- the assembly unit of the repair pipe sleeve is intended for the formation from the ends (29 and 30), as well as along the radial sections of the half rings of the bushings (26 and 27) of the welds (31-34), designed to form a monolithic connection of two pipelines (6 and 7) with the assembly unit of the repair tube sleeve (35), equipped with equidistant stops (36 and 37), necessary to coordinate the length of the half rings (26 and 27) when forming radial clearances of the welds (33 and 34).

Node execution example

The assembly of the repair pipe sleeve, consisting of a welded joint of two pipes of equal diameter, is performed in such a way that:

- the assembly unit of the repair pipe sleeve is located relative to the pipe sleeve (1) with an axial stop symmetrically located on its surface (2);

- relative to the axial stop (2), on the surface of the tube sleeve (1) are two symmetrically equally spaced relative to the axial stop sections of fiberglass (3);

- two sections coaxially and on top of the bushings (4 and 5) are displaced along the axis (7) with the overlapping of the opposed ends (29 and 30) of the pipelines (6 and 7) along the outer surface (8) of the bush (1);

- bushings (4) and (5) are made with opposed conical protrusions (9-12) with an arrangement of annular stops (13-16) arranged to accommodate fiberglass sections (17 and 18) along the annular perimeter;

- the conic sections (12 and 13) farthest from the stop (2) along the outer surface (19 and 20) of the bushings (4 and 5) are equipped with ring cuffs (21 and 22) designed for axial movement of the self-hardening mastic (23) inside the ends of the ends connected pipelines (6 and 7);

- along the length L of the repair area of the coaxially located bushings, fiberglass (24) is placed around the circumference;

- and on the surface of the fiberglass fabric (24 and 25), half rings (26 and 27) are installed, equal in diameter and thickness to the pipelines (6 and 7), designed to be welded together in axial and radial directions relative to the axial stop (2) interacting with the trapezoidal groove (28) relative to axis (7);

- the assembly unit of the repair pipe sleeve is intended for the formation from the ends (29 and 30), as well as along the radial sections of the half rings of the bushings (26 and 27) of the welds (31-34), designed to form a monolithic connection of two pipelines (6 and 7) with the assembly unit of the repair tube sleeve (35), equipped with equidistant stops (36 and 37), necessary to coordinate the length of the half rings (26 and 27) when forming radial clearances of the welds (33 and 34).

The industrial usefulness of the new technical solution lies in the combined approach of connecting two ends of pipelines that are distant from each other due to damage to the pipe section due to cracking or rupture.

The economic usefulness of the new technical solution consists in a significant saving in time spent on repairs of a high complexity category. A repair unit extends the service life of pipelines by tens of years, and the reliability of its joints is guaranteed against weld beads entering the pipeline, which cannot be said about the known welded joints.
