Ultra-high molecular weight polyethylene fiber lining pipe oil pipe and production method thereof

The invention relates to a lining pipe oil pipe prepared from ultra-high molecular weight polyethylene fibers. The lining pipe oil pipe comprises an oil pipe body and is characterized in that an inner pipe is fixedly mounted in the oil pipe body, and the two end faces of the inner pipe extend outwards and wrap the outer portions of the end faces of the oil pipe body; and the inner pipe is made of ultra-high molecular weight polyethylene composite materials or thermoplastic high-density polyethylene composite materials, and the thickness of the inner pipe is 4-6 mm. The lining pipe oil pipe is high in practicability and easy to popularize. 本发明涉及一种超高分子聚乙烯纤维制备的内衬管油管，包括油管，其特征在于：所述油管内部固定安装有内管，该内管的两端面向外延伸并且包裹在油管的端面外；所述内管为超高分子聚乙烯复合材料或热塑性高密度聚乙烯复合材料，所述内管的厚度为4-6mm。本发明实用性强，易于推广。
