Characteristics of ultra-high molecular weight polyethylene pipes

Ultra high molecular weight polyethylene pipe (UHMW-PE pipe) is a thermoplastic engineering plastic pipe with excellent performance, mainly characterized by:

Extremely high wear resistance: The wear resistance is superior to materials such as polytetrafluoroethylene, nylon, carbon steel, etc., and is 7 times that of steel.

Excellent impact resistance: The impact strength at room temperature is more than 10 times that of PE100, and the lower the ambient temperature, the stronger the impact resistance.

Excellent chemical stability: able to withstand corrosion from various corrosive media and organic solvents, more corrosion-resistant than plastics such as polyethylene, polypropylene, nylon, ABS, etc.

Good self-lubricating properties: With a low coefficient of friction, it reduces the resistance of material movement in pipelines and improves conveying efficiency.

Unique low temperature resistance: performs well in environments ranging from -269 ℃ to+80 ℃.

Non adhesiveness: The surface has strong non adhesiveness, making it difficult to hang materials and reducing blockage.

Long lifespan: The ultra-high aging and embrittlement rates are very slow, and after 50 years of underground use, its mechanical performance only decreases by about 20%.


Easy installation: mainly using flange connection, easy to disassemble and install, reducing installation and maintenance costs.

The difference between ultra-high molecular weight polyethylene pipes and high-density polyethylene

The main differences between ultra-high molecular weight polyethylene (UHMW-PE) pipes and high-density polyethylene (HDPE) pipes are reflected in the following aspects:

Molecular weight: The molecular weight of ultra-high molecular weight polyethylene is usually over 2 million, and even up to 3 million, while the molecular weight of high-density polyethylene is between 500000 and 1 million.

Performance: Due to the difference in molecular weight, ultra-high molecular weight polyethylene pipes are superior to high-density polyethylene pipes in terms of wear resistance, impact resistance, and corrosion resistance.

Appearance: Ultra high molecular weight polyethylene has a black and shiny appearance, smooth hand feel, strong toughness, and high tensile strength; High density polyethylene, on the other hand, is relatively dull and has a lower surface glossiness.

Application areas: Ultra high molecular weight polyethylene pipes are more suitable for applications that require high wear resistance, high impact resistance, and high corrosion resistance due to their excellent performance, such as mining, dredging, and other fields; High density polyethylene pipes are more commonly used in fields such as water supply, sewage, and irrigation.

Application of ultra-high molecular weight polyethylene pipes in mining and dredging fields

Mining field: Ultra high molecular weight polyethylene pipes are widely used in transportation systems, equipment manufacturing, and pipeline transportation in the mining industry. Its excellent wear resistance, impact resistance, and self-lubricating properties enable the pipeline to withstand the friction and impact of materials such as ore and mineral powder for a long time, significantly extending the service life of the pipe. At the same time, its corrosion resistance also makes the pipeline perform well when transporting acidic, alkaline, or other corrosive media.

In the field of dredging, ultra-high molecular weight polyethylene pipes are used to clean and transport sediment in waterways. Its wear resistance and impact resistance enable the pipeline to withstand the erosion and wear of materials such as sediment, while its self-lubricating properties also reduce the movement resistance of materials in the pipeline, improving transportation efficiency.
