Ultra-high molecular weight polyethylene (UHMWPE) is a kind of new engineering thermoplastics with more than 3 million viscosity-average molecular weight. Ultra-high molecular weight polyethylene pipe has superior performance over conventional HDPE pipe such as very high wear resistance, impact resistance, excellent resistance to internal pressure strength, resistance to environmental stress cracking, intrinsically self-lubricating, anti-adhesion, low temperature resistance and excellent chemical resistance.
Uses of UHMWPE Pipe :
Mineral Sands Pipelines
Mine tailing Pipelines
Mine Concentrate Pipelines
Water and Sewerage Pipelines
Advantages of UHMWPE Pipe Over Steel Pipe :
40 times the abrasion resistance of steel
8 times lighter than steel
5 times lower coefficient of friction than steel
The pressure loss of UHMWPE pipe is 1/10 of steel pipes
Attributes of UHMWPE Pipe :
Abrasion resistance –
UHMWPE pipes have excellent abrasion resistance providing long life in abrasive slurry applications.
Chemical resistance –
outstanding resistance to a wide range of chemical reagents allows the use of UHMWPE systems in tailing pipelines and chemical treatment applications used in mining operations.
UHMWPE pipes can be bent to a minimum of 30 times the pipe’s outside diameter for HDPE. This flexibility and resiliency allows the pipe to absorb surge pressures, vibration and stresses caused by soil movement. This makes
the pipes particularly useful in submarine pipe lines, mine subsidence and earthquake prone areas.
High flow capacity –
low friction compared with materials such as fibre reinforced cement and resistance to material deposit buildup give UHMWPE pipes long lived high flow capacity.
Lower pumping cost –
due to greater hydraulic capacity as compared with steel and HDPE pipes.
Easy of installation –
UHMWPE is easy to install with light weight and steel flanges.
