Embodiment Construction
[0032] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.
[0033] A pipe with a steel skeleton polyethylene winding structure wall, which is composed of an inner wall layer 3 and an outer wall layer 4. The inner wall layer is made of sheet polyethylene strips spirally wound on a drum mold, and the edges of each adjacent strip are overlapped and fused in sequence A continuous solid-walled tube is formed.
[0034] Its innovation lies in that the outer wall layer is made of a steel strip 2 bent into an Ω-shaped section as the skeleton, and the polyethylene strip is wrapped on the outer surface of the steel strip and spirally wound on the outer surface of the inner wall layer to form a convex reinforcement. The ribs are formed, and the protruding reinforcing ribs are spirally pressed across the overlapp...
