Ultra-high-molecular-weight polyethylene pipes can be used for transporting various solid-liquid mixtures or liquids that are highly abrasive and strongly corrosive—such as mineral slurries, mortar, acidic solutions, alkaline liquids, crude oil, tailings slurry, coal-water slurry, as well as ash and slag discharge from power plants. Compared to steel pipes, they offer significant advantages.

Product Details
Product Introduction
Ultra-High Molecular Weight Polyethylene Pipes refer to pipes manufactured by extruding ultra-high molecular weight polyethylene (UHMW-PE) material through specialized plastic pipe extruders. This thermoplastic engineering plastic is created via the polymerization of ethylene and butadiene monomers under catalytic action, resulting in an average molecular weight exceeding 2.5 million. Due to its exceptionally high molecular weight, UHMW-PE boasts outstanding comprehensive properties, including superior wear resistance, impact resistance, corrosion resistance, and self-lubricating capabilities—earning it the nickname "amazing plastic." In 2001, UHMW-PE pipes were officially listed as a key national scientific and technological achievement for promotion under Document No. Keji Zi (2000) 056 issued by the Ministry of Science and Technology. As a new chemical-material innovation and product, UHMW-PE pipes have been identified as a priority area within China’s current high-tech industrial development strategy. These ultra-high molecular weight polyethylene pipes are ideally suited for transporting highly abrasive and corrosive solid-liquid mixtures or pure liquids, such as mineral slurries, cement mortars, acidic or alkaline solutions, crude oil, tailings slurry, coal-water slurry, and even ash and slag discharge from power plants. Compared to steel pipes, UHMW-PE pipes offer significant advantages: under conditions of extreme corrosion and intense abrasion, their service life can be extended by several times—or even up to tenfold. Additionally, the smooth, non-scaling inner surface of these pipes, combined with their low coefficient of friction and exceptional impact resistance, allows for reduced operating pressures or smaller pipe diameters. This makes them particularly well-suited for long-distance transportation in challenging outdoor environments.
