Description
Technical field
The utility model relates to fire protection pipeline technical field, specifically, relates to buried high pressure resistant plastic composite pipe for a kind of fire-fighting.
Background technique
In recent years, along with the harmfulness of all kinds of fire is increasing, all take much count of the research and development production work of fire-protection equipment both at home and abroad, in particular for carrying the withstand voltage anticorrosive pipeline of fire water.At present, fire-fighting water conveyance conduit is mainly welded steel pipe, cast iron tube, Coating Steel Pipe, this four class of the safe steel-plastic composite pipe of plastic-coated.
There is following defect in welded steel pipe, cast iron tube and Coating Steel Pipe: 1, very easily because potential corrosion produces pitting corrosion, need to use fire water fire fighting, help time, hydraulic pressure is just not high; 2, in the spraying system of fire fighting not circulating, be easy to the blockage phenomenon because internal incrustation gets rusty, cause can not spraying timely and effectively water outlet in the time that fire occurs, put out burning things which may cause a fire disaster, cause larger loss throughout the year; 3, outside gets rusty easily, befouling environment, and working life is lower.
Although the safe steel-plastic composite pipe part of plastic-coated has solved corrosion-resistant phenomenon, its compression resistance is still not enough, and the impact such as plastics thickness, the method for coating of the safe steel-plastic composite pipe of plastic-coated because applying, and its effect difference is also very large.In addition, the corrosion protection of joint cannot effectively solve so far.
The patented technology of domestic this aspect mainly concentrates on plastic steel pipe, such as the patent that: patent publication No. is CN201748049U, CN201875359U, CN203068061U, CN2535641Y, CN201612965U, CN201651585U is all made research antirust around how, such as: the modification of epoxy resin, application, the application of multilayer multiple material, electroplating technology makees the outside antirust or outside Stainless Steel Tube of directly taking and makes the modes such as composite pipe.Although these technology all obtain obvious effect in corrosion aspect anticorrosion, technique is relatively more complicated, can not ensure body effects on surface damage and consequential injury of bringing in transportation process.
In addition, the patent that patent publication No. is CN20178721U discloses a kind of plastics composite fire pipe, and the outer composite material plastic layer of plastics and rubber that uses is to play a protective role, and mesosphere is nylon fiber layer, and internal layer is common plastics.Such pipeline can meet the usage requirement of certain pressure, and can solve Anticorrosion, but nylon, plastics and rubber are unlike materials, and the compatibility between them cannot effectively solve, and uses for a long time quality of rubber materials easily aging, has potential safety hazard.
Model utility content
The purpose of this utility model is, buried high pressure resistant plastic composite pipe for a kind of fire-fighting is provided, to solve above-mentioned technical problem.
For achieving the above object, the technological scheme that the utility model adopts is:
A kind of buried high pressure resistant plastic composite pipe for fire-fighting, is characterized in that: comprise polyethylene double-resisting inner tube layer and polyethylene double-resisting external tube layer, be provided with at least one deck continuous fiber prepreg tape mesosphere between polyethylene double-resisting inner tube layer and polyethylene double-resisting external tube layer; Described continuous fiber prepreg tape mesosphere forms by laser action welding with the multilayer continuous fiber prepreg tape being wrapped on polyethylene double-resisting inner tube layer that longitudinally interlocks by being hoop; Described continuous fiber prepreg tape is continuous fiber and enhancing thermoplastic resin composite material presoaked belt, described continuous fiber is at least one in glass fibre, basalt fibre, carbon fiber, and described enhancing thermoplastic resin is the one in polypropylene, high density polyethylene (HDPE) or nylon.
Say further, be coated with wear-resisting coating layer on the outer surface of described polyethylene double-resisting external tube layer, described wear-resisting coating layer is polyurea elastomer coating or hydrogenation nitrile rubber coating; The thickness of described wear-resisting coating layer is 0.3-0.4mm.
Beneficial effect: compared with prior art, the utlity model has following advantage:
1, inner tube layer and external tube layer are all to adopt polyethylene double-resisting material to make, not only there is good fire-retardant, antiseptic property, and light, the convenient installation of quality, when mounted, between interface, can adopt the modes such as hot melt contracting cover to connect, can avoid the scabrous problem of connection corrosion of plastic-steel class tubing;
2, mesosphere adopts the continuous fiber prepreg tape of good pressure-resistant performance, not only can improve the compression resistance grade of tubing, and, can realize the control to tubing compression resistance grade by controlling the winding number of plies of continuous fiber prepreg tape and the thickness of each layer of continuous fiber prepreg tape, produce and use more convenient reliable;
3, the thermal expansion coefficient in polyethylene double-resisting inner tube layer, polyethylene double-resisting external tube layer and continuous fiber prepreg tape mesosphere is basically identical, can effectively solve plastic-coated steel in use invar, moulding material thermal expansion coefficient is inconsistent causes delamination and destroyed problem.
