  • Product name: UHMWPE Pipe in Chemical Industry
  • item No: 1016

 

       

 

 

Because the UHMWPE pipe has small frication resistance, self-lubrication property,high wear resisting, it can be widely used in pneumatic conveying field, effectively reduce the wear and corrosion resistance in the process of conveying, and reducing power consumption in the process of delivery.It has bvious advantages in the aspect of construction installation and efficiency

Characters of UHMWPE Pipe

 

• Abrasion resistance – UHMWPE pipes have excellent abrasion resistance providing long life in abrasive slurry applications.
• 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
• Adders 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

 

Product is checked and re-checked at every stage to ensure fault-free performance
