Description

Novel annular reinforced polyethylene composite plastic pipeline
Technical Field
The invention relates to the technical field of composite plastic pipelines, in particular to a novel annular reinforced and reinforced polyethylene composite plastic pipeline.
Background
At present, wire net reinforcing polyethylene composite pipe is because of its advantages such as corrosion-resistant, health, simple to operate, and the wide application is defeated water, irrigates the field, nevertheless because traditional wire net reinforcing polyethylene pipeline adopts the steel wire alternately winding reinforcing structure, and the steel wire twines with 54.7 angles more, and the steel wire number of piles generally is bilayer or four layers, and the not enough that this kind of pipeline embodies at the actual motion in-process is: the number of winding layers and the number of steel wires are large, the ring stiffness is limited, the ring stiffness needs to be improved by adding a resin layer, and the cost advantage is not obvious.
At present, the problem cannot be well solved in the known patents or the prior art, so a novel annular reinforced and reinforced polyethylene composite pipeline is provided
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a novel annular reinforced polyethylene composite plastic pipeline, the nominal pressure of the pipeline can reach 2.5MPa, the long-term service life of the pipeline can reach more than 50 years, and the problems are effectively solved.
In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a novel hoop reinforcement enhancement polyethylene composite plastic pipeline, includes the composite bed, the composite bed is six layers of composite construction, and is inlayer, first adhesive linkage, enhancement layer, reinforcement layer, second adhesive linkage and skin from inside to outside in proper order.
Further, the inner layer is made of polyethylene resin, the first bonding layer and the second bonding layer are made of bonding resin, the reinforcing layer is made of high-strength steel wires, the stiffening layer is made of spring steel wires, and the outer layer is made of polyethylene resin. The reinforcing layer is formed by spirally and crosswise winding a high-strength steel wire at an inclination angle of 49 degrees with the radial direction, and has the characteristics of high circumferential and radial strength and less wire consumption.
Further, the inner layer and the outer layer are polyethylene resin of PE100 grade or PE80 grade. The stiffening layer adopts a spring steel wire and is wound along the annular direction of the pipe, so that the stiffening layer has the characteristic of stiffening.
Compared with the prior art, the technical scheme of the application has the following beneficial effects:
this novel compound plastic conduit of reinforcing polyethylene is strengthened to hoop, compound tubular product inner wall adopts the polyethylene resin material, consequently there is not the corrosion problems, spiral cross winding and hoop winding reinforcing about through the steel wire, effectively reduce the resin quantity, the pipeline can adopt electric smelting muffjoint, safe and reliable, in water supply and drainage pipe field, even farmland low pressure irrigation field, can replace traditional steel pipe, it is corrosion-resistant to have, it is low to synthesize the cost, long service life, a great deal of advantage such as later maintenance low becomes, easily popularization.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-2, the novel circumferential reinforced polyethylene composite plastic pipe in the embodiment includes a composite layer, which is a six-layer composite structure and includes an inner layer 1, a first adhesive layer 2, a reinforcing layer 3, a reinforcing layer 4, a second adhesive layer 5, and an outer layer 6 in sequence from inside to outside.
The inner layer 1 is made of polyethylene resin, the first bonding layer 2 and the second bonding layer 5 are made of bonding resin, the reinforcing layer 3 is made of high-strength steel wire, the stiffening layer 4 is made of spring steel wire, and the outer layer 6 is made of polyethylene resin. The reinforcing layer 3 is formed by spirally and crosswise winding a high-strength steel wire at an inclination angle of 49 degrees with the radial direction, and has the characteristics of high circumferential and radial strength and small wire consumption.
The inner layer 1 and the outer layer 6 are PE100 grade or PE80 grade polyethylene resins. The stiffening layer 4 adopts a spring steel wire and is wound along the annular direction of the pipe, and the stiffening layer has the characteristic of reinforcing and stiffening.
The polyethylene resins of the inner layer 1 and the outer layer 6 are PE 100-grade high-performance polyethylene mixed materials, have the characteristics of corrosion resistance, heat resistance, pressure resistance and the like, and are added with the anti-aging master batches according to a certain proportion to increase the anti-aging performance.
The steel wire of the reinforcing layer 3 is a high-strength aluminum-plated steel wire, and can be better tightly bonded with the adhesive resin layer by utilizing the characteristics of metal aluminum.
The steel wire of the stiffening layer 4 is a carbon spring steel wire, the inclination angle of the steel wire is determined by the proportion of the distribution width and the pipe diameter of the steel wire, and the angle between the steel wire and the section of the pipe is 5-10 degrees.
The adhesive resin of the first adhesive layer 2 and the second adhesive layer 5 is an adhesive resin using polyolefin graft ethylene copolymer and maleic anhydride copolymer as a matrix, and the adhesive resin can form ionic bond with metal aluminum of the outer surface layer of the aluminum-plated steel wire of the reinforcing layer 3, and shows good adhesive strength.
As the six-layer composite structure is adopted, when fluid is conveyed, the inner polyethylene pipe of the inner layer 1 bears conveying pressure, the compressive strength is improved through the reinforcing layer 3, the hoop allowable stress is increased, the hoop winding structure of the rigid layer 4 is increased, and the hoop rigidity of the pipe can be effectively increased, so that the application of resin materials of the inner layer 1 and the outer layer 6 is further reduced, and the material cost is reasonably reduced. The material properties of the adhesive layer 2 and the adhesive layer 5 enable the reinforcing layer 3 and the stiffening layer 4 to be tightly bonded to the inner layer 1 and the outer layer 6, respectively.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
