Compared with the prior art, the beneficial effects of the utility model are that:
the HDPE reinforced polyethylene winding pipe steel belt is combined with polyethylene, and due to the fact that the expansion coefficient difference of expansion caused by heat expansion and contraction caused by cold of the two materials is large, the two materials are easy to separate under the condition of large temperature difference change, the service life is affected, and the problem that water leakage cannot be solved is caused. The continuous fiber reinforced polyethylene (CFPE) winding pipe is made of thermoplastic materials such as plastic-impregnated continuous glass fiber reinforced strips (glass fiber strips for short in the prior commodity), so that the expansion coefficients are easy to bond together, the continuous fiber reinforced polyethylene (CFPE) winding pipe cannot be layered due to thermal expansion and cold contraction, and the plastic-impregnated continuous glass fiber reinforced strips have high strength and completely meet the requirements of relevant standards, so that the continuous fiber reinforced polyethylene (CFPE) winding pipe is the best choice for the conventional reinforced winding pipe.
2. The utility model discloses there are two kinds of casts, one kind is that the arris of taking of book system is coiled to compound strip (being extruded the cladding by fine strip of glass through polyethylene and forming), and another kind is that the polyethylene body (polyethylene can adopt other thermoplastics to replace) goes up integrative formation spiral arris suddenly, and adopts fine strip of glass as framework material and reinforcing in this arris, consequently, two kinds of casts all have better compressive property. The winding pipe is widely applied to water supply and drainage engineering and ventilation and exhaust engineering, and has the characteristics of low manufacturing cost, high strength of the pipe body, sanitation, harmlessness, long service life, good heat expansion and cold contraction resistance and the like.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
A continuous fiber reinforced polyethylene winding pipe is characterized in that a composite strip is formed by wrapping polyethylene on a plastic-impregnated continuous glass fiber reinforced strip, the composite strip is wound and welded by a winding forming machine to form the winding pipe, a spiral protruded ridge protruding out of a pipe body is arranged on the winding pipe, and the plastic-impregnated continuous glass fiber reinforced strip is positioned in the center of the protruded ridge. Fig. 2 shows that when the glass fiber strip (purchased goods) passes through the compounding machine head, polyethylene is extruded out and the glass fiber strip is coated, and then the composite strip is prepared through cooling, shaping, drawing, cutting and rolling.
Fig. 2 shows that the composite strip is used for manufacturing a pipe by a winding forming machine, and then is subjected to cutting and incision plastic package. Referring to fig. 1, the polyethylene tube has a spiral polyethylene ridge protruding from the tube, and the plastic-impregnated continuous glass fiber reinforced strip is located at the center of the polyethylene ridge.
The utility model discloses an its structure of continuous fibers reinforcing polyethylene (CFPE) winding pipe is the winding pipe shaping, and the fine material shape of continuous glass of plastics flooding satisfies pipeline technical index and is accurate.
The utility model provides a current HDPE reinforcing Polyethylene (PE) winding pipe steel band combine with the polyethylene, because the expend with heat and contract with cold expansion coefficient difference of two kinds of materials is big, if separate easily under the big condition of difference in temperature change, influence life, cause the problem that can't solve of leaking.
The main production process of the pipe comprises the following steps: the continuous production process of the reinforced polyethylene (CFPE) winding pipe comprises two processes of strip production and pipe winding forming: the plastic-impregnated continuous glass fiber reinforced strip (outsourcing commodity) and Polyethylene (PE) are compounded into a special-shaped strip and wound into a disc (similar to a cable), and then the disc-packed plastic-impregnated continuous glass fiber reinforced strip and the Polyethylene (PE) composite special-shaped strip are wound and welded to form the composite pipe (the winding equipment is simple and convenient to transport, so that the process can be transferred to a construction site or nearby to implement).
Because the continuous glass fiber reinforced strip material impregnated with the plastic and the Polyethylene (PE) are thermoplastic materials, the bonding is firm, the layers are never formed, and the bonding is safe and reliable.
The main requirements of the production process are as follows: after the plastic-impregnated continuous glass fiber strip reinforcement and polyethylene are compounded into the special-shaped strip, the bonding temperature is well controlled during winding, and the pipe wall with an integral structure is ensured to be compounded.
The two main processes of coating and extrusion winding for pipe production are as follows:
the technological process of the plastic-impregnated continuous glass fiber reinforced strip and the polyethylene composite strip mainly controls the temperature of a heating and constant temperature box to melt the plastic on the surface of the plastic-impregnated continuous glass fiber reinforced strip and ensure the bonding strength; the other important point is to control the extrusion speed and the traction speed of the extruder to ensure the stable thickness of the coating.
