What is UHMWPE?
Ultra-high molecular weight polyethylene (UHMWPE) is a new kind of 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.
Role of Molecular Weight
UHMWPE denotes Ultra High Molecular Weight Polyethylene which is a polyethylene polymer with an average molecular weight is greater than 3,100,000 as defined by ASTM D4020 – Standard specification for UHMWPE polymers. This molecular weight is well above the molecular weight of most typical polymers which are between 1,000,000 and 400,000 thus earning the title Ultra-High Molecular Weight Polyethylene. Polyethylenes with molecular weight in the 3.1 -4.5 Million range have been found to exhibit the best combination of impact strength and abrasion resistance. For Polyethylene molecular weight classification the following guidelines can be used:
HDPE (High Density Polyethylene): 100,000 – 400,000 MW
HMWHDPE (High Molecular Weight High Density Polyethylene) 500,000 – 1,999,999
VHMWHDPE (Very High Molecular Weight High Density Polyethylene) 2,000,000 – 3,100,000
UHMWPE (Ultra High Molecular Weight Polyethylene) > 3,100,000 + MW
Advantages of Ultra PE Pipe Over Steel Pipe:
40 times the abrasion resistance of steel (ref. Madsen)
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 and 1/7 of nylon pipes.
Benefits:
UHMWPE pipes offer high wear and abrasion resistance, making them ideal for slurry pipe and dredging pipe.
The low friction of UHMWPE pipe enables solid particles to slide easily over the surface and avoids scaling and fouling.
The smooth interior surfaces of UHMWPE pipes assure low friction loss and high flow rate.
