High molecular weight polyethylene composite pipe for slurry conveyance, which features an inner lining made of high molecular weight polyethylene tubes for wear or corrosion resistance, and a steel pipe (welded pipe, spiral pipe, seamless pipe, etc.) as the pressure-resistant outer sheath for protection. The two are compounded using special process equipment. This product, while retaining all the performance advantages of high molecular weight polyethylene pipes, also boasts the following new features: 1. Higher pressure resistance: The composite pipe can withstand pressures up to 5MPa-10MPa, meeting the requirements for various high-pressure pipeline applications such as underground backfilling, tailings conveyance, and crude oil transportation. 2. High temperature resistance: With the support of the steel pipe, it can overcome the high-temperature deformation of UPE pipes, allowing the working temperature to reach approximately 80°C. 3. Overcomes the defects of plastic pipes, such as easy bending and sagging, making it more aesthetically pleasing as process pipelines in workshops or overhead pipelines outdoors. 4. Mature supporting technology; the company holds multiple utility model patents for steel-lined high molecular weight polyethylene pipes.
