UHMWPE Mining Pipe

I want to make an inquiry

UHMWPE Mining pipe


What is UHMWPE

Ultra High Molecular Weight Polyethylene (UHMWPE)  is a linear polyethylene with molecular weight of over2.5X 10^6 which is approximately ten times that of high  molecular weight high density polyethylene resins. The extremely high molecular weight of this resin offers superior performance of UHMWPE to any other thermal engineering plastic

  • Highly wear resistance

          4 to 7 times more wear resistant than PE 100 and Q235 steel

  •  Extremely smooth surface

          Surface roughness of UHMWPE is 0.00022mm

  • Self-lubricating / non scaling


  • Superior impact resistance


Corresponding parameter set not found, please add it in property template of background

UHMWPE mining pipe

DRAGON, started in 2002, with 24 UHMWPE pipe production lines, overcame the difficulty of extrusion UHMWPE through improvement of equipment, formulation design, cooling system and technical parameters to achieve the continuous extrusion of UHMWPE pipe from DN30 to DN 1200 with molecular weight of 2.5 million to 9.2 million

Properties of UHMWPE pipe for mining

  • High Wear Resistance

         UHMWPE has the best wear resistant among all the engineering plastics. The higher molecular weight of the material is the more wear resistant of the UHMWPE pipeis. UHMWPE pipes are 4 to 7 times more wear    resistant than PE 100 or Q235 carbon steel, 2.7times of SiMn 13 steel.Thus offers UHMWPE pipe longer life, less maintenance cost and downtime loss.



  • High impact strength, flexible and light

          The impact resistance of UHMWPE pipes is 5 times that of HDPE pipe, 2 times that of PC pipe and 10 times that of PTFE pipes.
          It means easy installation and less installation cost


  • Extremely smooth/ Non scaling / less pumping cost

         UHMWPE pipes have very smooth surfaces with low friction loss and high flow rate.
         Surface g roughness of UHMWPE pipe is 0.00022mm, which provides UHMWPE Pipe far superior anti-scaling properties to any other                 pipeline on the market today. It saved maintenance cost of acid cleaning pipes.

        UHMWPE has a friction coefficient of 0.05, compared to 0.28 for HDPE or 0.58 for Steel (ISO8295). Along with the benefits mentioned                 above, UHMWPE Pipes also offer significant cost savings through increased pumping efficiency.
        It means less friction loss, less pressure loss and greatly reduced energy inputs.


  •  High corrosion resistance

       For its saturated molecular structure, it has high chemical stability, resistance to all kinds of corrosive medium (acid, alkali, salt) and organic          solvent.    It will offer longer life than other pipelines in acid or corrosive applications.

  • Working temperature       

       -269 Degrees C to 85 degrees C.

  • Environmental friendly
  • UHMWPE is colorless, odorless and non-toxic.  UHMWPE pipe is extruded out from pure virgin UHMWPE unless some additives required by clients.
