Abstract
The utility model relates to a plastic/steel composite pipe, which comprises a steel pipe. The inner part of the steel pipe is inlaid with a plastic pipe layer. An adhering layer is arranged between the plastic pipe layer and the inner wall of the steel pipe. The utility model combines the steel pipe, the adhering layer and the plastic pipe layer into integration. The utility model has the characteristics of high strength, good rigidity, no flexural deformation, smooth and fluent inner wall, no rust, no scale deposition, conveying quality assurance, etc.
Description
The utility model relates to tubing, is applicable to that mainly delivery temperature is no more than 50 ℃ water and other fluid under the low pressure.
Existing low-pressure fluid is carried and is used tubing, as life give, waste pipe, general metal tube or the plastic tube of adopting, the characteristics of metal pipe are that mechanical strength is better, can not be out of shape, but that its shortcoming is a tube wall are coarse, the easy fouling of tube wall, result in blockage, though be surperficial on the other hand through zinc-plated processing, but still can get rusty.The characteristics of plastic tube are inner wall smooths, do not allow fouling, guarantee in the pipe smoothly, but that its shortcoming is a mechanical strength is relatively poor, and can bending etc. distortion.
It is that metallic material is made that the purpose of this utility model provides a kind of outside, and interior pipe is plastics, and constitutes one by medium material, has both overcome the defective of prior art, brings into play the plastic steel composite pipe material of characteristics separately again.
The technological scheme of the utility model plastic steel composite pipe material is: a steel pipe is arranged, it is characterized in that the embedded plastic pipe layer of steel pipe, be shaped on adhesive layer between plastic pipe layer and steel pipe inwall.
Plastic steel composite pipe material of the present utility model has steel pipe outward, in plastic pipe layer is arranged, between steel pipe and plastic pipe layer, be shaped on adhesive layer, triplicity is integral, and skin has been brought into play mechanical strength height, good rigidly, can bending etc. distortion, the smooth smoothness of inner layer wall, non-corrosive, non-scaling, make the life-span of composite pipe long, carry characteristics such as quality assurance.
Fig. 1 is the utility model plastic steel composite pipe equipment structure schematic representation.
Below in conjunction with Fig. 1 embodiment of the present utility model is done detailed explanation.
The utility model plastic steel composite pipe material is made up of steel pipe 1, plastic pipe layer 2 and adhesive layer 3.Can make steel pipe by methods such as welded pipe or cold rolling, cold-drawing seamless pipe or hot seamless tubes during production, steel pipe is through zinc-plated processing, and the steel pipe of making type is standby.Make plastic tube by plastic raw materials such as polyethylene or rigid polyvinyl chloride or polypropylene in addition, outer wall at plastic tube is coated binder, the plastic tube that scribbles binder is inserted in the steel pipe, again whole pipe is dropped in the heater, the heating of heater is controlled heating-up temperature between 140-250 ℃ according to the difference of plastic material, the pressurized air that charges into 0.4-0.6MPa when reaching certain demand temperature makes steel pipe and moulds the complete strong bonded of pipe, whole pipe is rolled in the heating road to be heated entirely, continization is produced, and the plastic steel composite pipe material is connected firmly.
Claims (1)
1, a kind of plastic steel composite pipe material has a steel pipe, it is characterized in that the embedded plastic pipe layer of steel pipe (1) (2), is shaped on adhesive layer (3) between plastic pipe layer and steel pipe inwall.
