Abstract
The utility model discloses a glass reinforced plastic and metal wire compound pipeline, which belongs to a compound rigid underground pipe. The glass reinforced plastic and metal wire compound pipeline comprises a lining layer, a glass reinforced plastic material layer, a heat-insulating layer and an outer protective layer which are sequentially formed from inside to outside; and a metal wire which is spirally wound in the direction of a center line of the pipeline is clamped in the glass reinforced plastic material layer. With the design, the metal wire is clamped in the glass reinforced plastic material layer to form a mixed body of glass reinforced plastic and metal, so that the tensile force and the strength of the glass reinforced plastic pipeline can be improved. The compound pipeline can be prevented from being broken or deformed due to the geological change, so that the pipeline is more suitable for direct burial; and the compound pipeline has a broader prospect of being used as a conveying pipeline in projects requiring the transportation of terrestrial heat water and corrosive fluid with the heat-insulating requirement.
Description
Technical field
The utility model relates to combination rigidity underground pipe, specifically is the metal wire combined pipeline of a kind of glass fibre reinforced plastics.
Background technique
Because the glass fibre reinforced plastics material has advantages such as hard, corrosion-resistant, in recent years, fiber reinforced plastic pipe extensive use in water supply and sewage work.Particularly when carrying underground heat to supply water and being corrosive fluid, adopted joint socket to connect the fw frp thermal insulation pipe as conveyance conduit.
Chinese patent 2514200 discloses a kind of " fiber reinforced plastic pipe ", bellmouth, straight length and columniform socket by expansion shape are formed, be characterized in: pipe material is a glass fibre reinforced plastics, the bellmouth of one end is expansion shape, with the pipe shaft straight length one changeover portion is arranged, the bellmouth port is a chamfering, the other end is a socket, it is shaped as hollow cylinder, with the pipe shaft straight length one changeover portion is also arranged, its periphery is provided with 1-2 bar groove, in order to be nested with rubber seal, rubber seal is the seal ring of water-swellable, and its expansivity is 1.5-2 a times of volume.
Chinese patent 2426057 discloses a kind of " heat-insulation and heat-preservation Glass Steel Tube ", and it is to coat the foamed plastics that one deck plays the heat-insulation and heat-preservation effect, its outer fw frp again outside glass fibre reinforced plastics is responsible for.The utility model be responsible for to adopt glass fibre reinforced plastics, and is corrosion-resistant, flow resistance is little, is responsible for the frp layer of outer cladding foam thermal insulation thermal insulation layer and protection foamed plastics, good heat-insulation effect, long service life, easily installs.As transport pipe the time, the heating station standoff distance that can extend, flow is big simultaneously.The utility model can be used as the pipeline of oil transportation, defeated hot water, uses at cold area, can prevent condensing of wax class high-melting-point composition in the crude oil, saves the energy, also can prevent water freezing and the pipe explosion accident that freezes and cause.
Though fiber reinforced plastic pipe possesses above-mentioned advantage, have in the engineering practice of uniform temperature and temperature guarantee requirement in conveying, when particularly meeting geology and changing, or pipeline pressure the phenomenon that a large amount of fiber reinforced plastic pipe fracture, are out of shape still occurs when surpassing 15kg.
The model utility content
The utility model is exactly in order to solve the distortion and the problem that fractures that fiber reinforced plastic pipe in the prior art occurs, and a kind of metal wire combined pipeline of glass fibre reinforced plastics that significantly improves frp pipe intensity is provided.
The utility model is realized according to following technological scheme.
The metal wire combined pipeline of a kind of glass fibre reinforced plastics comprises the inside liner, glass fibre reinforced plastic material layer and the external protection that form successively from inside to outside, and is folded with the wire that twines along pipe centerline direction spiral in the glass fibre reinforced plastic material layer.
The metal wire combined pipeline of a kind of glass fibre reinforced plastics comprises the inside liner, glass fibre reinforced plastic material layer, thermal insulation layer and the external protection that form successively from inside to outside, and is folded with the wire that twines along pipe centerline direction spiral in the glass fibre reinforced plastic material layer.
She Ji the utility model owing to be folded with wire in the glass fibre reinforced plastic material layer, has constituted the mixture of glass fibre reinforced plastics and metal like this, and the pulling force of fiber reinforced plastic pipe and intensity are improved.Avoided the phenomenon that fractures, be out of shape occurring, made pipeline be more suitable for the characteristics of direct-burried, in the engineering of carrying the insulation of underground heat water supply and corrosive fluid and tool to require, had more the use prospect as conveyance conduit because of geology changes.

Embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
The metal wire combined pipeline of a kind of glass fibre reinforced plastics comprises the inside liner 1, glass fibre reinforced plastic material layer 2 and the external protection 3 that form successively from inside to outside, and be folded with wire 5 in glass fibre reinforced plastic material layer 2, thus the composite bed that becomes one.
The metal wire combined pipeline of described glass fibre reinforced plastics, its wire 5 twines along pipe centerline direction spiral.
The metal wire combined pipeline of described glass fibre reinforced plastics, its wire 5 are 1 or many metal filaments arranged side by side at a certain distance.
The metal wire combined pipeline of described glass fibre reinforced plastics, its wire 5 are single steel wire or plying steel wire.
The metal wire combined pipeline of described glass fibre reinforced plastics is formed with thermal insulation layer 4 between its glass fibre reinforced plastic material layer 2 and the external protection 3.
The metal wire combined pipeline of a kind of glass fibre reinforced plastics comprises the inside liner 1, glass fibre reinforced plastic material layer 2, thermal insulation layer 4 and the external protection 3 that form successively from inside to outside, and is folded with the wire 5 that twines along pipe centerline direction spiral in glass fibre reinforced plastic material layer 2.
That is folder is established wire 5 and the composite bed of formation in the glass fibre reinforced plastic material layer 2 between thermal insulation layer 4 and inside liner 1.
When the utility model is made, twine glass fiber, when coating unsaturated polyester resin slurry reaches certain thickness, twine wire 5 to pipe range, then with the 0.5-2cm spacing simultaneously, continue to twine glass fiber, coating unsaturated polyester resin slurry again, to the thickness that meets product requirement, solidify.The utility model of Xing Chenging because wire 5 is folded in the glass fibre reinforced plastic material layer 2, can not expose like this, avoids the corrosion of wire 5.
The utility model sample when pipeline pressure reaches 40kg, distortion, fracture can not occur after tested.
