Abstract
The present invention relates to a steel-plastic composite pipe material for transmission of fluid. It is characterized by that the thin steel band is uniformly wound round its inner layer plastic pipe, the both are joined together by using adhesive to obtain the invented integrated steel-plastic composite pipe. By using same method, said invention also can be made into the steel-plastic composie pipe with three-layer structure, i. e. its external layer can be plastic pipe, middle layer is steel pipe and internal layer is plastic pipe. Said invention can implement large-scale continuous production, can raise production efficiency and reduce pipe cost.
Description
The present invention relates to a kind of piping material of conveyance fluid.
Steel pipe is present the most frequently used piping material.Because its easy-to-rust not only reduces the pipeline life-span, and influences the quality of institute's conveyance fluid.For this reason, begin the challenge that it just is subjected to plastic tube from the fifties.But, limited the using scope of plastic tube greatly owing to aspects such as intensity.Therefore, people begin one's study and have the steel-plastic composite pipeline material of steel pipe and plastic tube advantage concurrently, and have applied for following patent: ZL87103183, ZL92101686.7, ZL92107347.X, ZL92206100.9, ZL92210521.9, ZL92215503.8, ZL93210938.1, ZL93238361.0, ZL94247039.7, ZL95104155.X, ZL96242528.1.These patents all are the outer steel pipes that is, internal layer is a plastic tube, between the internal and external layer by coolly pull out, different modes such as roll extrusion, sealing pressurization, splicing combine.Its manufacturing process trouble is not suitable for production continuously in enormous quantities, and manufacturing efficiency is low.And cost of production is also far above the steel pipe cost.
The present invention seeks to provide a kind of winded steel-plastic composite materials for pipelines, makes it to enhance productivity, and reduces the tubing cost.
The object of the present invention is achieved like this: steel band is wrapped on the plastic tube equably, and steel band and plastic tube rely on splicing and are integral, thereby making internal layer is plastic tube, and skin is the Clad Steel plastic composite pipeline material of steel pipe.In addition, also require the corrosion-resistant piping material for skin, on above-mentioned Clad Steel plastic composite pipeline material, the outside is winding plastic band equably again, remain between plastic tape and the steel pipe to rely on to glued joint and form one, thereby make the outer plastic tube that is, the middle level is a steel pipe, and internal layer is the Compound Steel plastic composite pipeline material of plastic tube.Thickness of strips determines that according to the caliber size caliber is more little, and thickness is also more little.For the tubing of nominal diameter 6-150mm, can adopt thickness is the book steel band of 0.5-2mm.For major diameter tubing or require high strength linepipe, can adopt the multilayer steel band to be entwined, between the steel band for glueing joint combination.
The present invention is because tubing utilizes splicing that steel band directly is wrapped on the plastic tube to be made, and technology is simple, can produce continuously, thereby improve manufacturing efficiency.In addition, also, save steel, adopt and glued joint, reduce energy consumption,, be not higher than the steel pipe cost so the tubing cost is lower owing to adopt the book steel band to twine.
Concrete manufacturing process of the present invention is provided by following embodiment and accompanying drawing thereof.
Accompanying drawing is the schematic representation of the manufacturing process of the double-deck winded steel-plastic composite materials for pipelines of proposition according to the present invention.
Describe in detail according to the winding of the present invention's proposition or the concrete manufacturing process of steel-plastic composite pipeline material below in conjunction with accompanying drawing.
Outer surface in PVC plastic tube (1) is coated acrylate adhesive A component equably.On the splicing face of steel band (2), coat the B component equably.Then plastic tube (1) and steel band (2) are placed in the middle of the roller of multiple roll mechanism (3), and steel band (2) is pressed on the plastic tube (1).Along with roller turn, steel band (2) is wrapped on the plastic tube (1).Behind the adhesive solidification, steel band (2) just is glued on the plastic tube (1) securely, thereby makes steel-plastic composite pipeline material.
Claims (3)
1. the steel-plastic composite pipeline material of a conveyance fluid, it is characterized in that the pipe internal layer is plastic tube (1), outer for adopting steel band (2) to be wrapped in upward formed steel pipe of plastic tube (1) equably, internal and external layer relies on to glued joint and becomes one, thereby makes the Clad Steel plastic composite pipeline material.
2. steel-plastic composite pipeline material according to claim 1, it is characterized in that on the Clad Steel plastic composite pipeline material, the outside is winding plastic band equably again, rely between the two to glued joint and become one, thereby make the outer plastic tube that is, the middle level is a steel pipe, and internal layer is the Compound Steel plastic composite pipeline material of plastic tube.
3. according to claim 1 and 2 described steel-plastic composite pipeline materials, it is characterized in that steel pipe is to be entwined by the multilayer steel band, be the splicing combination between the steel band.
