Preferably, the distance between the two reinforcing rings is any value between 10 and 15 times the inner diameter of the inner pipe.
The invention has the beneficial effects that:
the invention provides a high-strength corrosion-resistant polyethylene composite pipe, which comprises an inner layer pipe, a middle reinforcing layer, a plurality of reinforcing rings and an outer layer pipe. The inner layer pipe is made of polyethylene material. The middle reinforcing layer is made of high-strength aluminum alloy and comprises a plurality of reinforcing strips attached to the outer surface of the inner-layer pipe and used for reinforcing the strength of the pipeline. The strengthening ring interval sets up in the surface of middle part enhancement layer, and fixes through the reinforcing bar of welded mode and middle part enhancement layer, and the reinforcing bar adopts high strength aluminum alloy to make. The outer layer pipe is made of polyethylene materials, covers the outer surfaces of the middle reinforcing layer, the inner layer pipe and the reinforcing ring and is used for preventing the middle reinforcing layer and the reinforcing ring from being corroded. Through inlayer pipe and outer pipe with the beaded finish and the reinforcing bar parcel at middle part, prevent that beaded finish and reinforcing bar from being corroded (polyethylene plastics have good anticorrosive performance), and the beaded finish and the reinforcing bar at middle part can strengthen the holistic intensity of tubular product, and then make the compound tubular product of polyethylene have high strength and corrosion-resistant advantage, and then can be applicable to the place that has intensity and corrosion resistance requirement. And the combination of the reinforcing rings and the reinforcing strips is adopted instead of a whole reinforcing metal pipe, so that the weight of the pipe can be greatly reduced, and the pipe has the advantage of light weight.
The section through will strengthen the strip sets up to crescent to the inner ring camber that makes the enhancement strip is the same with the outer surface circle's of inlayer pipe camber, and the outer loop camber of strengthening the strip is the same with the inner circle camber of beaded finish, makes the inlayer pipe hugged closely to the internal surface of strengthening the strip, the internal surface in close contact with of the surface of strengthening the strip and beaded finish. And then make and closely cooperate between inlayer pipe, reinforcing bar, the beaded finish, improve additional strengthening's enhancement effect.
By providing the outer surface of the reinforcing ring with a rounded corner, stress concentration at the edge of the reinforcing ring on the outer tube is reduced (stress concentration is reduced in the form of a smooth transition).
