Abstract
The utility model discloses a composite corrugated pipe, which takes a corrugated steel pipe as a substrate; a galvanizing coat is arranged on a pipe wall; a plastic-coated layer is at least arrangedon the galvanizing coat of the inner wall surface thereof; and each layer is tightly combined into a whole. Meanwhile, the plastic-coated layers can be arranged both on the galvanizing coats of the inner wall surface and the outer wall surface of the corrugated steel pipe. The composite corrugated pipe greatly improves the corrosion resistance of pipelines, which is improved by 2-3 times than theservice life of the normally used steel pipe; the galvanized corrugated structure thereof leads the comprehensive mechanical strength to be far more than that of common steel pipes, and has the advantages of convenient construction and installation when being matched with a shaping flange as well as good tightness.
Description
Technical field
The utility model relates to the pipeline that is used for draining, particularly a kind of composite corrugated water pipe, with realize its high corrosion resistance can effect.
Background technique
The glassware for drinking water of flowing through in the waste pipe system has certain pH value and is mixed with sandy soil etc., thus require the pipeline should be corrosion-resistant, wear-resistant again, mechanical strength is high and construction and installation are convenient, good airproof performance.
Summary of the invention
The utility model provides a kind of composite corrugated water pipe, and is compound with metallic material and macromolecular material, adopts the technology of fusion stickup to make the plastic-steel composite board PE film and galvanized steel plain sheet, makes to cover on shaping equipment again and moulds corrugated steel tube.It has possessed the high anti-corrosive properties of the high rigidity of steel pipe and plastic tube simultaneously in one, and reliability greatly improves, and long service life reaches 100 years.
The technical solution of the utility model is: a kind of composite corrugated water pipe is characterized in that: be matrix with the corrugated steel tube, the tube wall face is provided with zinc coat, on the zinc coat of wall, is provided with polyethylene overlay film layer at least within it, and combining closely between each layer is integral.Also can on the zinc coat of the inside and outside wall of corrugated steel tube, be equipped with to cover and mould layer.
Advantage of the present utility model and beneficial effect: the utility model has greatly improved the decay resistance of pipeline, improves 2-3 doubly working life than steel pipe commonly used; Its zinc-plated ripple struction makes its comprehensive mechanical intensity much larger than common steel tube; Be equipped with convenient, the good airproof performance of moulding flange construction and installation.
Description of drawings
Fig. 1 is the sectional drawing of the utility model;
Fig. 2 is the enlarged view of the utility model tube wall hierarchy.
Embodiment
Referring to Fig. 1,2, corrugated steel tube matrix 1, its inside and outside wall is provided with zinc coat 2, and wall is provided with overlay film layer 3 (or inside and outside wall all is provided with) at least within it, and combining closely between each layer is integral, and becomes whole composite pipe.At the pipe two ends is to be used for the plastics flange 4 that pipeline connects, and realizes connecting reliably by the bolt support.
Formation technique of the present utility model, can be at first cover and finish covering of steel strip surface on the coating line and mould at steel plate, the insulation pressing of comprise surface clean, heating, cover macromolecule felted-membrane, PE film and steel plate (can be at steel band and the intermembranous one deck macromolecule felted-membrane that covers earlier of PE, then moulding PE film is distributed in steel strip surface, adopts smelting process) PE film and steel band pressing bonding; Cover the steel band of moulding and enter the helical corrugation steel tube shaping machine finishing, become pipe, at last the disposable injection-compression molding plastics flange at the steel pipe two end part respectively through manufacturing processs such as roll wave moulding, two side flangings, interlock volume circles.
Claims (2)
1, a kind of composite corrugated water pipe is characterized in that: be matrix with the corrugated steel tube, the tube wall face is provided with zinc coat, on the zinc coat of wall, is provided with polyethylene overlay film layer at least within it, and combining closely between each layer is integral.
2, composite corrugated water pipe according to claim 1 is characterized in that being equipped with to cover on the zinc coat of the inside and outside wall of corrugated steel tube moulding layer.
