Description
Technical field
This utility model relates to pipeline corrosion protection parts, especially a kind of bridging type heat shrinking sleeve.
Background technology
Transporting for long-distance oil, natural gas steel pipe, pipeline network of fuel gas in city, heat supply steel pipe at oil and gas industry, in running water pipe, its welding position is easily subject to corrosion, and this is accomplished by welding position or the inner tube that exposes are carried out preservative treatment.Traditional pyrocondensation belt troublesome poeration, and interface quality is unstable；Closed type heat shrinking sleeve can well be set on pipe connection portion position, thus carries out anticorrosion, yet with pipeline after installing through being subjected to impact and the friction in the external world, heat shrinking sleeve is easily damaged or is stripped, and this allows for anticorrosion premature failure.Closed type heat shrinking sleeve is limited by production technology, and the production cycle is longer, relatively costly, it is low to produce qualification rate, thickness error is relatively big, and when causing installing heating, heat shrinkable is irregular, and installation rear surface stress distribution is uneven, affects preventing corrosion of repaired mouth quality.
Summary of the invention
This utility model solves deficiency of the prior art, it is provided that a kind of easy to use, saves time, laborsaving, the formula that the connects heat shrinking sleeve of low cost.
The technical solution of the utility model is:
A kind of bridging type heat shrinking sleeve, by thermal contraction base material, reinforcing fiber layer, hot melt adhesive layer, solid ring oxygen layer is constituted；Described reinforcing fiber layer is arranged on the inner side of thermal contraction base material；Described hot melt adhesive layer is arranged on the inner side of reinforcing fiber layer；Described solid ring oxygen layer arranges the inner side of hot melt adhesive layer；Aerofluxus rib it is provided with, the parallel head and the tail two ends being communicated to heat shrinking sleeve of described aerofluxus rib on the inwall of solid ring oxygen layer；The laminated structure docking that described bridging type heat shrinking sleeve is made up of thermal contraction base material, reinforcing fiber layer, hot melt adhesive layer, solid ring oxygen layer is rolled into cylinder-like structure, docking overlapping position is directly fixed by the way of welding or hot melt adhesion, it is fabricated to pipe box shape by lamellar in use according to the diameter of pipeline, convenient and swift.
Further, described thermal contraction base material uses radiant crosslinked polyethylene as base material.
Further, described reinforcing fiber layer is polypropylene fiber material.
Further, described polypropylene fibre bundle direction is identical with the length direction of heat-shrink tube.
Preferably, the thickness that described reinforcing fiber layer is is 0.05mm-0.1mm.
Preferably, the laminated structure joint registration that described bridging type heat shrinking sleeve is made up of thermal contraction base material, reinforcing fiber layer, hot melt adhesive layer is 10%.
Preferably, aerofluxus rib quantity is at least 2.
Further, the described semicircle that aerofluxus rib is evagination, rectangle or trapezoidal.
This utility model has a following beneficial effect:
1. by arranging reinforcing fiber layer between shrink wrap layer and hot melt adhesive layer, can effectively improve the intensity of shrink wrap layer, reinforcing fiber layer selects polypropylene fiber material, polypropylene fiber engineering properties is tough, anti-multiple organic solvent and acid and alkali corrosion, it is corrosion-resistant that this makes bridging type heat shrinking sleeve also be able to, extended shelf-life；
2. lamellar pyrocondensation belt lap-joint base material is in advance directly carried out good welding or hot melt adhesion according to the diameter of pipeline by this utility model, and be provided with on the inwall of solid ring oxygen layer to 2 aerofluxus ribs, solve series of problems in the construction such as hollowing, bubble at all, can effectively ensure that the preserving and sealing effect of opening-supplementing material；This utility model has the advantages such as product quality is more easily-controllable, production cost is low, it is short to produce delivery cycle, installation is simple, and can improve construction speed.
