UHMWPE Pipe Reduce the Downtime and Increase your Throughput:

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.

An easy way to envisage UHMWPE is to think of a plate of cooked spaghetti with the long strands all intertwined. If the spaghetti is cut up, it would closely approximate the molecular appearance of regular HDPE. Since very long strands of spaghetti approximating the chains of UHMWPE are completely intertwined it would be very difficult to pull them apart. This simplification explains the outstanding abrasion resistance (the difficulty in pulling out particles of the polymer).

UHMWPE Pipe Advantages:

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.

1. Excellent Wear Resistance:

Of all the pipe materials, UHMWPE pipes exhibit the smallest abrasion index. Of all the plastic pipes presently available,

the anti-abrasion performance of UHMWPE is 18 times higher than phenolic polymers, 6 times higher than polyamide polymers (PA66), 5 times higher than poly(tetrafluoroethylene) (PTFE) as well as being 6.6 times higher than carbon steel, 5.5 times higher than stainless steel and 27 times higher than copper, ideal for sand and slurry discharging;

2. Low surface roughness, Higher flow rate, Saving Pumping Costs

UHMWPE pipes have smooth interior surfaces which assure low friction loss and high flow rate. Because UHMWPE pipe do not rust, pit, scale, or corrode, the high flow rate continues for the life of the piping system. The internal roughness of UHMWPE pipe is only 0.0010 mm thus the pressure loss of UHMWPE pipe is about 1/10 of steel pipes resulting in an over 20% of increase in transfer efficiency.Since the internal wall of UHMWPE pipes is very smooth this practical prevents fouling or scale formation on the inner wall of the pipe and hence there is no drop in pumping efficiency;

3. Minimized Maintenance time&Costs, Less Downtime, Less loss of production

The far superior wear resistance of UHMWPE pipe will significantly increase the time between pipe replacements and rotation, which will largely reduce:

a. reduced maintenance costs and time;

b. reduced downtime for maintenane and less loss of plant production time;

4. High strength, drurable material

UHMWPE pipes are highly resilient(Elongation reaches 500%), tough and durable products that have high-tensile strength (30Mpa) and high-impact strength(Notched Izod Impact strength reaches 166kj/m2). They can withstand high pressure for long periods. In this case, the UHMWPE pipes could withstand various impacts from sand and slurry;

5. Corrosion Resistance

With higher structure stability ,UHMWPE pipes are corrosive resistant to sea waters. No electro chemical corrosion, no need anti-corrosive coating;

6.Lightweight

UHMWPE pipes are lightweight – approximately one-half the weight of aluminum and one-eighth the weight of steel – reducing transportation, handling, and installation costs.

7.Easy Connection:

The UHMWPE pipelines could be connected by steel flanges, easy to install and dismantle at the working sites.

Furthermore, the UHMWPE pipe ends will be turned up to work as gaskets, the flat sealing face and good verticality will keep good sealing and well protect the flanging part not easy to be worn out.

I.  UHMWPE VS. HDPE Material

II. Performance Comparisions between UHMWPE pipes&HDPE pipes

 1. Good Wear Resistance enables the UHMWPE pipes to have longer service life

Based on the sand and slurry testing,UHMWPE has an abrasion resistance 4.4 times higher than HDPE.

2.  Less Maintenance Time and Costs, Less Downtime,Less Loss of  Production

The far superior wear resistance of UHMWPE pipes will significantly increase the time between pipe replacements and rolling

which can significantly:

1) Reduce maintenance costs and time

2) reduce downtime for maintenance and less loss of plant production line

3. Reduced Pumping Costs

With a surface roughness of 0.00022mm while HDPE is 0.01mm, UHMWPE pipe is extremely smooth, which means less friction, less pressure loss and 20%  energy inputs will be reduced to deliver the same result:
