Description

Technical Field

[0001] The present application relates to the field of carat tubes, and in particular to wear-resistant high-density polyethylene carat tubes. Background Art

[0002] Carat tube is a hot-wound high-density polyethylene (HDPE) wound structural wall tube. This wall tube is made of high-density polyethylene resin as the main raw material, using hot-wound technology, and polypropylene (PP) single-wall corrugated pipe as the supporting structure to form a special structural wall pipe with high external pressure resistance. The wound tube wrapped around the tube body is prone to deformation when subjected to external extrusion, affecting the overall support effect.

[0003] The structure of the product can refer to a B-type carat tube disclosed in Chinese patent document publication number: CN219493344U, which includes a main body and a rib tube that is circumferentially spirally wound along the outer wall surface of the main body, the rib tube includes an inner tube and a coating layer coated on the outer wall surface of the inner tube, a pad is provided at the bottom of the inner tube, the pad is placed at the connection between the main body and the coating layer, and the bottom of the pad is a smooth surface.

[0004] In the above structure, the rib tubes are supported by the pads, but the rib tubes themselves are prone to deformation, resulting in a poor supporting effect.

[0005] Therefore, a kind of wear-resistant high-density polyethylene carat tube with firm support is needed. Utility Model Content
