UHMW-PE Elbow
Ultra-high molecular weight polyethylene (UHMWPE) is a kind of engineering thermoplastics with more than 3 million viscosity-average molecular weight. It differs from PE standard grades in its very high degree of polymerization. Ultra-high molecular weight polyethylene pipe has superior performance over conventional HDPE pipe such as very high wear resistance, impact resistance, intrinsically self-lubricating, anti-adhesion,low temperature resistance and excellent chemical resistance.

Ultra-high molecular weight polyethylene (UHMWPE) is a kind of engineering thermoplastics with more than 3 million viscosity-average molecular weight. It differs from PE standard grades in its very high degree of polymerization. Ultra-high molecular weight polyethylene pipe has superior performance over conventional HDPE pipe such as very high wear resistance, impact resistance, intrinsically self-lubricating, anti-adhesion,low temperature resistance and excellent chemical resistance.
Can be widely used in metallurgy, mining (mineral mud conveying, backfilling by grouting), power (fly ash conveying), sand dredging pump (lake dredging mud conveying, sand pump pipe of pumping vessel), oil, natural gas, textile, papermaking, food, chemical, mechanical, electrical and other industries.
UHMWPE Elbow dimensions show as below, they that can be equip with PIPE in different conditions:
90 degree elbow，60 degree elbow ,30 degree elbow,45 degree elbow, T type elbow
| Features |
• 5x lower surface roughness (ISO 8295)
• Increased temperature capability (particularly in the lower range), capable of -70 to +80 deg C operation
• Comparable elongation performance
• Anti-aging agent reduce UV degradation by comparison and otherwise increases design life
• Colourless, odourless and non-toxic
• Formed flanges, allowing for clean alignment. Mn16 inserts used at flange end to reduce turbulence down the pipe or bend
• Much higher corrosion resistivity, comparable to Teflon
• Higher tensile and yield tolerances
• Can be provided that make UHMWPE flameproof (allowing for minimal degradation in environments where this is a factor, UHMWPE will still ignite at 300 deg C, but will immediately self-rectify)
• Lighter and more durable, allowing for heavily reduced installation costs as large excavation and crane equipment will no longer be required
• Unlike other materials, UHMWPE is self-lubricating (part of why it is used as a ball material for hip joint replacement)
• All this allows UHMWPE to improve on ANY process currently utilising HDPE and most that include Steel
