Technical Field

[0001] The utility model relates to a steel belt reinforced polyethylene spiral corrugated pipe with wave crest reinforcement. Background Art

[0002] In modern industry and infrastructure construction, pipelines are an important tool for transporting liquids, gases or solid particles. They are widely used in water treatment, oil and gas transportation, chemical fluid transmission and other fields. Traditional pipeline materials include steel pipes, plastic pipes, concrete pipes, etc. These pipes have their own advantages, but they also have some limitations that are difficult to overcome, such as heavy weight, easy corrosion, difficult installation, and high cost.

[0003] In order to solve these problems, scientific and technological personnel have developed a variety of new pipe materials and structural designs. Among them, steel-reinforced polyethylene spiral corrugated pipes have attracted widespread attention due to their excellent performance. This pipe is a new type of pipe with high strength, wear resistance and corrosion resistance by compounding steel and polyethylene materials. However, most of the existing steel-reinforced polyethylene spiral corrugated pipes adopt a single wave crest design, which to some extent limits their performance when subjected to complex stresses.
