Plastic steel winding pipe

Abstract

The invention discloses a plastic steel winding pipe. The plastic steel winding pipe comprises a plurality of corrugated pipes; a female connecting opening and a male connecting opening which can be mutually snapped are formed in two openings of every corrugated pipe; every corrugated pipe comprises an inner pipe and strip-shaped sectional materials; the strip-shaped sectional materials wind on the inner pipes in a spiral shape; gaps are formed in one lateral side of the strip-shaped sectional materials along the length direction; the gaps cover the other lateral side of the strip-shaped sectional materials in an occlusal mode when the strip-shaped sectional materials wind on the internal pipes. According to the plastic steel winding pipe, the strip-shaped sectional materials wind on the internal pipes, so that the straight pipe bending is achieved when winding is achieved, meanwhile the inner wall smoothness is not influenced, and water flow unobstructed resistance is reduced; the ring stiffness of the plastic steel winding pipe is adjusted due to adjustment of the strip-shaped sectional materials to satisfy different production wall requirements; the connection which can be performed through capacitance technology is rapid and convenient due to the fact that heating wires are buried in the connecting openings in advance.

Description

technical field [0001] The invention relates to a winding pipe, in particular to a plastic-steel winding pipe. Background technique [0002] Due to the advantages of corrosion resistance, light weight, easy installation, large flow rate and long life, plastic-steel winding pipes are environmentally friendly and green products, and have gradually replaced pipes made of high-energy-consuming materials such as cement, cast iron, and ceramics. [0003] However, the current plastic-steel winding pipe still has the following shortcomings: it needs to be connected with a special flared joint during use, which causes unnecessary difficulties in engineering construction, and is time-consuming, labor-intensive, and has potential safety hazards; the plastic steel pipe is directly bent by the profile Forming, the inner wall is not smooth enough, and the water resistance is large, which seriously affects its performance; the plastic steel pipe has a large proportion and high manufacturin...
