Description

Technical Field

[0001] The utility model relates to the technical field of winding pipes, in particular to a metal core winding pipe. Background Art

[0002] With the continuous development of industrial technology and the continuous expansion of its application fields, the market demand for spiral wound pipes is also increasing, and the performance requirements for spiral wound pipes are also gradually improving. Among the spiral wound pipes currently available on the market, reference can be made to the Chinese utility model patent application number 2022225786329, which discloses a PP-reinforced HDPE polyethylene pressure-bearing spiral wound pipe. The pipe comprises a spiral wound pipe body and a rib spirally wound around the spiral wound pipe body, and the rib is integrally formed on the spiral wound pipe body. The rib also includes a pressure-resistant component, which is arranged on the outer inner wall of the spiral wound pipe body. The inner wall of the rib is provided with a first hollow hole, and the first hollow holes are arranged in a spiral shape. After the rib is wound around the spiral wound pipe body once, a group of ribs are formed. By providing the first hollow hole in the rib and providing the pressure-resistant component on the outer inner wall of the spiral wound pipe body, the patent achieves the effect of reducing the weight of the spiral wound pipe body while improving the pressure resistance of the spiral wound pipe body.

[0003] However, in the above structure, since a number of hollow holes are opened on the outer wall of the winding tube body, these hollow holes will make the tube wall thinner. When sharp objects scratch or pierce the tube wall, it is easy to cause the tube wall to rupture, thereby affecting the normal use of the pipeline; and if a solid tube wall is used, the weight of the tube body will be greatly increased and the material cost will increase, which has a low cost-effectiveness. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a metal core winding tube.

[0005] The technical solution adopted by the utility model to solve its technical problems is:
