9 Advantages of UNMWPE Pipes

Ultra-high molecular weight polyethylene UHMW-PE pipe are made of ultra-high molecular weight polyethylene raw materials with a viscosity average molecular weight of 3.5 million to 9.2 million. They are extruded under high temperature and high pressure by special machinery. They are widely used in blow filling, dredging, and mine tailings. Mine, ash and slag transportation and other fields.

9 Advantages of UNMWPE Pipes

1. High Wear Resistant

Compare with existing plastic pipes, Wear resistant UNMWPE pipe has the most excellent wear resistance which is 4 to 7 times that of Q235 steel pipe and 2.7 times that of wear-resistant steel 16Mn. Therefore it increases pipe flow rate and improves the transmission efficiency of more than 20%. The working life of UHMWPE pipes is more than 3 times that of wear-resistant steel pipe.

Ultra High Molecular Weight Polyethylene (UHMWPE) pipes are ideal for slurry and dredging pipelines because of their high abrasion and wear resistance.

The low friction of UHMWPE pipes allows solid particles to slide easily over the surface, avoiding scaling and fouling.

The smooth inner surface of UHMWPE pipeline ensures low friction loss and high flow rate. UHMWPE pipe has great advantages to replace traditional metal pipes in delivering abrasive media.

2. High Pressure Resistant

UHMWPE pipe is high pressure resistant and highly flexible. The compressive strength of UHMWPE pipe is 2 times to that of PE100 pipe and 2.5 times to that of PE80. UHMWPE pipes can withstand wide fluctuate of water pressure in the pipeline.

3. Anti Low Temperature

At the temperature of -70 ℃，UHMWPE pipe can work with normal mechanical performance. It is suitable for water supply and drainage in cold area.

4. Low Energy Consumption

Wear resistant UHMWPE pipe is self-lubrication and non-adhesive. Its coefficient of friction resistance is 0.009 while that of steel pipe is 0.013. With the same diameter, flow rate of UHMWPE pipe is larger than steel pipe, and with the same flow rate, UHMWPE pipe can save 25% energy.

5. Impact Resistant

Wear resistant UHMWPE pipe is greatly impact resistant which is 5 times that of HDPE pipe, 2 times that of PC pipe and 10 times that of PTFE pipes. With extraordinary impact resistance, UHMWPE pipe can withstand great water hammer impact when starting up pump.

6. Non-scaling

With roughness of 0.00022 and smooth pipe inner wall, it can efficiently avoid scaling without acid cleaning, which save a lot of maintenance cost.

7. Maintenance Free

With characteristics of corrosion resistance, low temperature resistance, non-scaling, no leakage, etc, UHMWPE pipe can work without extra anticorrosive coating, cleaning and maintenance which save more than 95% energy.

8.Environment Friendly

The manufacturing and processing of wear resistant UHMWPE pipe is low carbon and environment friendly with low emission of carbon dioxide which is 15% that of steel pipe and without discharge of wasted water, exhausted gas and waste residue which saves 20% energy compare with the traditional steel pipes.

9. High Flexibility

With high toughness and elongation of no less than 350%, the UHMWPE pipe and the connection site will not crack when crust settling which maximally ensure to supply water normally.

What is UHMWPE Material and How Is It Used?

https://www.pedredgepipe.com/resources/what-is-uhmwpe-material-and-how-is-it-used.html There are many possibilities available when selecting the appropriate polymers for your special projects, which can make it challenging to make a decision. UHMW plastic  could be the best option for you if you’re looking for a robust, lightweight, and long-lasting plastic. This plastic, often referred to as Ultra High Molecular Weight Polyethylene frequently goes under the radar and is not widely used by manufacturers and enterprises.   But as it turns out, this plastic is perfect for industrial and commercial uses. For a good reason, too—it offers a wealth of advantages over other kinds of plastic available on the market. Look at this:   What is UHMWPE Material ? UHMW stands for Ultra High Molecular Weight Polyethylene, as was previously mentioned. This material is robust and adaptable, with good abrasion, impact, and wear resistance while yet being relatively light. The large molecular weight and s

Why Using HDPE Pipes is More Beneficial ?

  The high-density polythene pipe market is growing. According to research, India   HDPE Pipes Market   for FTTx (Fiber to the x) industry was at $99.9 million in 2018 and will be reaching $233.5 million by 2026. Origin of HDPE Pipes The discovery of PE pipes began when people started looking out for a suitable and reliable medium to transport water and other fluid items from one place to another. During World War II, Low-density polythene was discovered and used in underwater cable coating. And In 1953, Karl Ziegler of the Kaiser Wilhelm Institute (renamed the Max Planck Institute) and Erhard Holzkamp discovered high-density polyethene (HDPE), a very close cousin to polyethene. Ziegler also won Noble Prize for Chemistry for his invention of HDPE. What is HDPE? High-density polyethene is a thermoplastic material. It is made of carbon and hydrogen atoms that are joined to produce Methane gas, which later converted to ethylene, and with the application of heat and pressure, it gets chang
