Abstract

The utility model relates to a track plug-in type pipeline restoration sleeve and belongs to the technical field of pipeline restoration tools. The track plug-in type pipeline restoration sleeve is composed of an upper half shell, a lower half shell, positioning bolts, and plugging bolts. The upper half shell and the lower half shell are equal-diameter steel shells, the cross sections of which are semicircular. A guide rail in the bottom edge of the upper half shell and a slide way in the top edge of the lower half shell are combined to form a plug-in type track and are fixed via fixing pins. The pipeline restoration sleeve adopts a plug-in type and thus is convenient and rapid to install. The pipeline restoration sleeve does not need welding or hot work and thus is safe and reliable in construction. The pipeline restoration sleeve is applicable to restoration and reinforcement of various steel pipelines in the case of local damages, and the restorable pipeline local damages include inner and outer wall corrosion, local crack, radial recess, outer wall scratch, and the like. The pipeline restoration sleeve can rapidly restore the damaged pipelines under pressure without stopping the transmission.

Background technique
Damage pipeline strength rehabilitation recovery technique is to guarantee oil and gas pipes integrity and extend the pipeline important means in working life.At present, to the Local Damaged steel pipes such as burn into crackle, depression, scratch can adopt built-up welding, plug welding, patch installing, knit oversleeve, the method such as sleeve, fixture, glass fiber compound material and carbon fiber composite winding carries out provisional or permanent reparation.Its middle sleeve/fixture note epoxy restorative procedure is because of advantages such as its mechanical strength are high, structural integrity is good, anti-corrosive durability is strong, and in pipeline strength rehabilitation technology, development rapidly.Patent 93104501.0 discloses a kind of method of pipe-repairing local damage, two cylindrical shape half shells are welded together, cylindrical envelope of formation around Pipeline damage part, thereby produce an inner space, Sealing is pressed to the annular flange of involucrum, by the sealing of this inner space, and with high pressure by this inner space of resin injection.The method forms sleeve by two and half shell welding and is arranged on pipeline, need to carry out on-the-spot fire operation, for very risky with pipeline especially oil-gas pipeline safety, applies limited.Patent 96197680.2 discloses a kind of modular sleeve for pipe protection, reparation or renewal; the liquid material of polymerization, for example polyurethane resin or epoxy resin are injected wherein; guarantee that the pipeline position that sleeve is covered protects or leak stopping; some identical module assemblings form injection mould; a male portion and a female part that each module is connected by an intermediate portion, the male portion of a module is suitable for setting-in in the female part of adjacent module.The method is assembled into sleeve by multiple modules, can be flexibly for various pipeline specifications, but Assembling workload is large, easily has gap and cause resin spill and leakage during assembling between module.Patent 200620003977.X discloses a kind of fixture of noting epoxy resin method pipe-repairing, by two box hats and Sealing, pressing plate and positioning block, formed, two relative outward edges of box hat have straight flange, exhaust port is arranged at box hat top, top, there is positioning screwn at box hat two ends, top, and inlet is arranged at bottom box hat bottom, at the two ends of box hat, has respectively lip ring and annular pressing plate, can, in stopping transportation situation not, steel tube defect position be repaired.Two and half shells of this fixture are fixed by straight flange and bolt, and the Placement of bolt exists corrosion and loosening risk.
Model utility content
The purpose of this utility model is in order to overcome the existing safety of getting angry of the sleeve interlinear notes epoxy resin pipe repairing methods such as welding type, modular type, bolt connecting type, the problems such as complexity, bolt failure to be installed, a kind of track plug-in type pipeline rehabilitation sleeve is provided, realize the not stopping transportation with pressure of burn into crackle, depression, scratch equivalent damage pipeline and repair fast and reinforcement, to reduce construction operation risk, simplify fitting operation flow process, to improve repair structure reliability.
A kind of track plug-in type pipeline rehabilitation sleeve of the present utility model, by upper half shell, lower half shell, holding down bolt, shutoff bolt, formed, holding down bolt has four and be symmetrically distributed in upper half shell and the two ends of lower half shell, upper half shell and lower half shell are that cross section is semicircle and isodiametric box hat, the slideway of the guide rail of upper half shell bottom margin and the top of lower half shell is combined to form plug-in type track, and is fixed by fixing pin; The bottom of lower half shell is provided with the injected hole injecting for epoxy resin, and the top of upper half shell is provided with three exhaust ports for Bas Discharged, and shutoff bolt seal is assemblied on exhaust port and injected hole.
There is reinforcement gusset slideway and lower half shell joint, and the gap of guide rail and slideway is by sealer shutoff.
The two ends of upper half shell are provided with the first half cycle closure plate of annular, and respectively there is a second annular half cycle closure plate at the two ends of lower half shell, and there is seal ring the first half cycle closure plate and the second half cycle closure plate inner side.
Upper half shell and lower half shell inwall are provided with guiding gutter, the guiding gutter degree of depth be no more than half shell wall thick 15%.
The utility model is applied to reparation and the reinforcement of various steel pipes in Local Damaged situation, recoverable pipeline local damage comprises inside and outside wall burn into localized cracks, radial depressions, outer wall scratch etc., can under stopping transportation, condition with pressure, not repair fast damaged pipe.Sleeve adopts plug-in mounting mode, quick and easy for installation; Welding and fire operation, construction safety is reliable; Plug-in mounting structure radially bearing capacity is good, improves reliability and the durability of repair structure; Overall structure favorable sealing property, overcomes epoxy resin and injects the problem of spill and leakage.
Accompanying drawing explanation
Fig. 1 is the utility model hoop schematic cross-section;
Fig. 2 is the utility model longitudinal cross-section schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
By Fig. 1,2 known: this repairing sleeve is comprised of upper half shell 1, lower half shell 2, holding down bolt 10, fixing pin 12, shutoff bolt 16.Upper half shell 1 and lower half shell 2 are that cross section is semicircle and isodiametric box hat, and the length of its box hat is 1.5 ~ 3 times of its diameter; The slideway 8 of the guide rail 7 of upper half shell 1 bottom margin and lower half shell 2 top is combined to form plug-in type track, and respectively there is 1 the first annular half cycle closure plate 3 at the two ends of upper half shell 1, and respectively there is 1 the second annular half cycle closure plate 4 at the two ends of lower half shell 2; Upper and lower half shell plug-in mounting becomes sleeve covers pipeline, and sleeve and pipeline enclosure form annular space; The two ends of upper half shell 1 and lower half shell 2 are symmetrically distributed with respectively 4 holding down bolts 10, for adjusting the distance of sleeve and pipeline enclosure.
