Abstract
The utility model discloses a seamless helically corrugated medium and low pressure conveying composite pipeline, which mainly solves the problems of no anti-corrosive property of a steel pipe, small aperture of a steel plastic composite pipe, and incompleteness, non-smoothness and high probability of leakage of the inner wall of a water conveying pipe of a spirally wound reinforcing layer on the inner wall of a water discharge pipe existing in the conventional low pressure conveying composite pipe. The seamless helically corrugated medium and low pressure conveying composite pipeline is characterized in that a reinforcing layer (2) and a polyethylene layer (3) are sequentially wound outside a core pipe (1), wherein a plastic coated steel band layer (4) is wound outside the polyethylene layer (3) and is covered by a composite layer (5). The seamless helically corrugated medium and low pressure conveying composite pipeline has the characteristics of material saving, smooth inner wall, good anti-corrosive property and high strength and ring stiffness.
Description
Technical field
The utility model relates to technical field of plastic, the seamless helical corrugation mesolow of a kind of specifically larger caliber composite tube for conveying road.
Background technique
The pipeline that is used for the mesolow conveying at present mainly contains plastic tube, steel and the compound composite metal plastic pipe of plastics that pure plastics are raw material except that traditional steel pipe.Many heavy caliber fluid-transporting tubings mainly adopt steel pipe, but its weight is big, and construction technical requirement is high, easily fed sheet of a media is polluted, and adds that its anti-corrosive properties are poor, and the working life of whole pipeline is shorter, and its cost is also higher.Plastic tube is compared with cement pipe with traditional metal tube, has lightweight characteristics, generally is merely the 1/6-1/10 of metal tube; Corrosion resistance is preferably arranged, and shock resistance and tensile strength are high, the plastic tube internal surface than cast iron tube smooth many, friction factor is little, fluid resistance is little, can reduce the water delivery energy consumption more than 5%; Synthesis energy saving is good; Convenient transportation is installed simply, reaches 30-50 working life.But plastic pipe must have certain wall thickness; To satisfy the requirement of its intensity and ring stiffness; The material that consumes on (like diameter greater than 800mm) its unit length when bore is big is also many; Along with bore increases, though satisfied the requirement of its opposing internal pressure, the ability of its opposing pressure outside can not meet the demands in addition.As reach simultaneously and satisfy the external and internal pressure requirement, its wall thickness then significantly increases, and manufacture cost can increase greatly, is difficult to accepted by people.
Many shortcomings such as composite metal plastic pipe that rose in nearly ten years such as SRPE etc. preferably resolve the withstand voltage not corrosion resistant of metallic conduit, the nonmetal pipeline corrosion resistant is not withstand voltage; Have rigidity and intensity preferably, but diameter 800mm can only be provided the product of following specification., application number relates to a kind of conduit pipe in being 201110204891.9 patent application; Its production method is in spiral twines the compound outer tube of enhancing that forms, to inlay the reinforcing fiber layer and the tubing of moulding; Because the liner reinforced layer is spliced by the ring-type enhancement layer that certain-length is arranged; Splicing seams adopts flame heating welding, hot blast heat welded and extrudes the mode of welding, and inwall is imperfect, rough, and the inwall resistance is big during fed sheet of a media; And the weld seam manufacturing process is harsh, and fed sheet of a media very easily leaks through weld seam.
Summary of the invention
In order to overcome deficiency above-mentioned in the existing technology; The utility model provides a kind of seamless helical corrugation mesolow composite tube for conveying road, and this is seamless, and helical corrugation mesolow composite tube for conveying road has saves that material, inner wall smooth, anti-corrosive properties are good, intensity and the high characteristics of ring stiffness.
The technological scheme of the utility model is: a kind of seamless helical corrugation mesolow composite tube for conveying road; Comprise the core pipe; Described core pipe outside is wound with enhancement layer, polyethylene layer successively, and the polyethylene layer outside is wound with the plastic-coated steel belt layer, and plastic-coated steel belt layer external packets is covered with composite bed.
Described core Guan Weichun moulds pipe.
Described enhancement layer material is a kind of in high density polyethylene (HDPE), polypropylene, PVC, the nylon, and perhaps any two kinds of materials in the above-mentioned material twine with from the inside to the outside order successively.
The vertical sectional shape of described plastic-coated steel belt layer is T shape, Ω shape or rectangle.
The utlity model has following beneficial effect: owing to take such scheme; On in type core pipe, twine enhancement layer and other composite bed; The inner-walls of duct of producing has guaranteed the characteristics that the plastic tube internal surface is smooth, friction factor is little, fluid resistance is little, and inwall is complete one, eliminated from inwall leak fed sheet of a media maybe; Inner-wall material is a pure material, and anti-corrosive properties are good; The core pipe coats the strength problem that has promptly solved pipeline behind other layer, also because to have twined sectional shape be intensity and the ring stiffness enhancing that the steel band of T shape or Ω shape makes this multiple tube.And because intensity and ring stiffness can guarantee, it is very thick to make the wall thickness of this composite pipe to process, and has saved material.

1-core pipe among the figure, 2-enhancement layer, 3-polyethylene layer, 4-plastic-coated steel belt layer, 5-composite bed.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
By Fig. 1 and shown in Figure 2, a kind of seamless helical corrugation mesolow composite tube for conveying road comprises core pipe 1, and described core pipe 1 is the pure pipe of moulding, and the material of core pipe 1 can be a kind of in high density polyethylene (HDPE) (PE), polypropylene (PP), the adjudicate two cases together ethene (PVC).Core pipe 1 outside is wound with enhancement layer 2, polyethylene layer 3 successively; Described enhancement layer 2 materials are a kind of in high density polyethylene (HDPE), polypropylene, PVC, the nylon; Perhaps any two kinds of materials in the above-mentioned material twine with from the inside to the outside order successively, and enhancement layer 2 can twine one deck, two-layer even multilayer according to the pressure of the required conveying of pipeline.Polyethylene layer 3 outsides are wound with plastic-coated steel belt layer 4, and the vertical sectional shape along axial direction of described plastic-coated steel belt layer 4 is T shape, Ω shape or rectangle, can strengthen the intensity of pipeline like this.Plastic-coated steel belt layer 4 external packets are covered with composite bed 5.
More than each layer when twining because the pure core pipe 1 of moulding according to fixed angular speed rotation, supports the whole pure pipeline supporting frame of moulding core pipe 1 and moves according to certain speed vertically, can add water cooling as required when twining each layer.After whole pipe moved completion, all winding layers also twined completion, and important production process is accomplished in so far seamless helical corrugation mesolow composite tube for conveying road.Twine cooling back, the seamless helical corrugation mesolow composite tube for conveying of completion road the shaping processing is carried out at its two ends, this product can be that the core pipe is isometrical, also can pipeline be processed bellmouth for one section, and an end is processed socket.Owing to adopted pure steel belt layer 4 and other protective layer that core pipe 1 outer surface twines enhancement layer 2, increases ring stiffness of moulding, can manufacture the seamless helical corrugation mesolow of larger caliber composite tube for conveying road as required according to pure specification of moulding core pipe 1.
