Abstract
The utility model provides a high-strength steel-plastic composite pipe which comprises the following components: a stainless steel pipe layer, a first polypropylene pipe layer and a second polypropylene pipe layer; wherein the stainless steel pipe layer, the first polypropylene pipe layer and the second polypropylene pipe layer are successively coated from inside to outside. An aluminum pipe layer is provided between the first polypropylene pipe layer and the second polypropylene pipe layer. The side wall of the aluminum pipe layer is provided with small holes. The distance between two adjacent small holes is twice of the diameter of the small hole. According to the high-strength steel-plastic composite pipe provided by the utility model, the aluminum pipe layer is adopted for enlarging strength. The aluminum pipe layer is provided with small holes, so that two polypropylene pipe layers in and out the aluminum pipe can be better adhibited, thereby preventing separation of steel and plastic after long-term use. Shot blasting is performed on the external surface of the stainless steel pipe, thereby improving surface friction, and causing better adhibition with the polypropylene layer. The high-strength steel-plastic composite pipe provided by the utility model has the following advantages: large integral strength, high compression resistance, high adhibition degree between steel and plastic, and long service life.
