本发明公开一种复合超高分子量聚乙烯管材,其特征在于,它包括中间层设有的钢管,所述的钢管内外表面分别复合覆有超高分子量聚乙烯及高密度聚乙烯,所述内层的厚度与所述外层的厚度相等。本发明复合聚乙烯管材一次性合成为一个整体,是一种钢#铸型聚乙烯复合管材。它不仅具有钢的高强度,而且内层铸型的超高分子量聚乙烯具有自润滑、高耐磨、防腐蚀等性能,此外内外层之间紧密贴合,不易脱落,使用寿命长。另外复合层都是聚乙烯材料,使用特殊的成型工艺即可制作出具有高抗磨损、耐腐蚀的复合超高分子量聚乙烯管材。

The invention discloses a composite ultra-high molecular weight polyethylene pipe. It is characterized in that the polyethylene pipe comprises steel pipes in the middle layer. The inner and outer surfaces of the steel pipe are respectively coated by ultra-high molecular weight polyethylene and high density polyethylene. The inner layer has a thickness equal to the thickness of the outer layer. Thecomposite polyethylene pipe of the invention is synthesized into one whole at one time, and is a steel cast polyethylene composite pipe. The composite pipe has the high strength of steel, and its ultra-high molecular weight polyethylene in the inner layer mold has self-lubricating, high wear resistance and anti-corrosion properties. In addition, the inner and outer layers are closely attached, not easy to fall off, and have a long service life. Furthermore, according to the composite ultra-high molecular weight polyethylene pipe, the composite layer is made of polyethylene material, and a special molding process can be used to produce a composite ultra-high molecular weight polyethylene pipe with high abrasion resistance and corrosion resistance.
