Abstract
The utility model relates to an overlapping and winding type steel-plastic composite pipe, which belongs to a special product which is produced from a plastic. The overlapping and winding type steel-plastic composite pipe is used for cold and hot water supply pipelines of a building, a coal gas pipeline, an air conditioning pipeline, a cable wire penetrating pipeline, a petrochemical industry fluid conveyor pipe, etc. The overlapping and winding type steel-plastic composite pipe is characterized in that the overlapping and winding type steel-plastic composite pipe is orderly composed of a plastic inner pipe, a macromolecular inner adhesive layer, a steel belt material processing overlapping type steel circular pipe, a thin steel belt which is transversally winded on the steel belt material processing overlapping type steel circular pipe, a macromolecular outer adhesive layer, and a plastic outer pipe which are from interior to exterior. The overlapping and winding type steel-plastic composite pipe has the advantages that production line continuously produces, steel materials are saved, the cost of the steel belt material processing overlapping type steel circular pipe can be greatly lowered, inner and outer composite plastics can not be corroded, welding is not needed, the steel belt material processing overlapping type steel circular pipe has high productive efficiency, the rigidity and the intensity of a pipe material with large caliber can be ensured.
Description
A kind of overlap joint Wound type steel-plastic composite, what belong to metal tube does not have cutting substantially and with plastics-production particular product technical field, is mainly used in Building Cooling water water supply line, coal gas, air-conditioning duct, cable penetration pipe, petrochemical industry fluid delivery tube etc.
In the prior art, present common steel-plastic composite pipe on the domestic and international market has only from imports such as Japan.This import tubing all is to serve as a contrast a finished product plastic tube in fished pipe again, and heating is combined with each other the two then; Or in fished pipe, be coated with the skim plastics.No matter which kind of its production process is all discontinuous, all be secondary deep processing to fished pipe, thereby the cost height, the difficult sealing of section still needs great deal of steel and still has the corrosion problem.
The purpose of this utility model is to provide the solution of all can relying on one's own efforts of a kind of all manufacturing mechanisms, and can replace fished pipe with the continuous production in enormous quantities of tinuous production once-through with thin steel band, save steel, thereby can reduce production costs by a relatively large margin, do not need welding, manufacturing efficiency is higher, can guarantee rigidity and intensity that heavy caliber pipe is required, the overlap joint Wound type steel-plastic composite that total quality is good.
According to the physical property of steel band and the technological requirement of steel-plastic composite pipe, at existing questions in the prior art, basic design of the present utility model is: do not weld after folded thin metallic tubd selects for use steel band machine shaping to overlap in the middle of the inside and outside two layers of plastic pipe and promptly twine the thin steel band of one deck again on its outer wall, come off for preventing to cause, can make inside and outside two-layer steel pipe walls fixedly connected with spot welding 2 of whole story of take-up strap by elasticity.
Overlap joint Wound type steel-plastic composite described in the utility model, it is characterized in that this composite pipe from inside to outside successively by adhesive layer 2 in the plastic inner pipe 1 that bonds together mutually, the macromolecule, by the overlap joint type Steel Thin-Wall pipe 3 of thin steel band machine shaping and laterally be wrapped on its outer wall and outside the fixed thin steel band 4 of two-end-point solid welding at the whole story, macromolecule adhesive layer 5 and plastic outer tube 6 constitute.
The utility model has the advantages that required all manufacturing mechanisms all can settle a dispute by the parties concerned themselves, need not import, and can produce in enormous quantities with the tinuous production once-through, add with thin steel band and replace fished pipe, save steel, thereby can reduce production costs significantly, because of not needing welding, not only energy-conservation again, the manufacturing efficiency height, and can fundamentally prevent to scorch interior plastic tube in the welding process, further guarantee the high quality of whole composite pipe, because steel band has stronger elasticity, Cheng Guanhou generally has only the transverse force that expands outward, and the transverse force that can not generation inwardly contracts so its outer wall of overlap joint back twines thin steel band, can guarantee rigidity and intensity that heavy caliber pipe is required; Again because inside and outside equal composite plastic pipe can thoroughly be stopped the corrosion problem.
Accompanying drawing 1 is one of the utility model most preferred embodiment cross-sectional structure schematic representation;
Accompanying drawing 2 is the perspective view of the outer adhesive layer of composite high-molecular and plastic outer tube not.
In conjunction with the accompanying drawings and most preferred embodiment, further describe structure characteristic of the present utility model as follows: on the outer wall of the PE matter plastic inner pipe of extruding with plastic extruder 1, coat and clad the overlap joint type cylindrical steel tube 3 of one decks in the macromolecule behind the adhesive layer 2 earlier by steel band machine shaping, on its outer wall, tiltedly laterally twine again the thin steel band 4 of one deck and its at whole story two ends fix with spot welding, coat adhesive layer 5 outside the macromolecule at its outer wall again, clad polyethylene matter plastic outer tube 6 at last again.
Change as present embodiment:
1, the thin steel band that is wrapped on the overlap joint type outer wall of steel pipe both can closely be arranged whole coverings, also can stay certain distance all not cover;
2, the raw material of inside and outside plastic tube can be used crosslinked PE, PVC and other plastics instead.
