The invention discloses a steel-plastic composite pressure water pipe comprising an inner support layer and an outer covering layer. The cross section of both the inner support layer and the outer covering layer is circular. The inner support layer is made of a steel-plastic strip which comprises a plastic solid core strip body and steel wires which are evenly fixed in the solid core strip body. The solid core strip body and the steel wires therein all extend in the cylinder spiral direction so that the steel wires forms a cylindrical cavity and the inner tubular support layer having the same. The outer peripheral pipe wall of the inner tubular support layer is provided with the outer tubular covering layer which surrounds the inner support layer and covers the outer peripheral pipe wall of the inner tubular support layer. The outer tubular covering layer is made of plastic, and the inner peripheral pipe wall of the outer tubular covering layer is fixedly connected with the outer peripheral pipe wall of the inner tubular support layer in a face-to-face contact manner. The steel-plastic composite pressure water pipe is more reasonable in structure, forming cost is reduced greatly, forming process is further simplified, and the steel-plastic composite pressure water pipe can be promoted and popularized better and more widely.
