Ultra-high molecular weight polyethylene (UHMWPE) pipe is a popular choice for tailings pipes due to its excellent wear resistance, impact strength, and low coefficient of friction. It is a thermoplastic material with a molecular weight typically ranging from 3 to 6 million g/mol, which gives it unique properties such as high abrasion resistance, high impact resistance, and excellent chemical resistance.

Compared to traditional materials like steel, Uhmwpe Pipe offers significant advantages in terms of cost-effectiveness and durability. It is much lighter than steel, which reduces transportation and installation costs, and it has a longer service life, which reduces maintenance and replacement costs. UHMWPE pipe is also resistant to corrosion, which makes it ideal for use in harsh environments where acidic or alkaline tailings can cause damage to other materials.
Overall, the UHMWPE pipe is an excellent choice for tailings pipes due to its superior wear resistance, low maintenance requirements, and cost-effectiveness. However, it is important to consider the specific needs of each tailings system and consult with experts to ensure the most appropriate material is selected.
Properties of UHMWPE mining pipe:
a. High Wear Resistance
High wear resistance is 4 to 7 times that of Q235 steel pipe and 2.7 times that of wear-resistant steel 16Mn. The working life of UHMWPE pipes is more than 3 times that of wear-resistant steel pipes.
b. High Corrosion Resistance
UHMWPE material structure is a saturated molecular group, with great chemical stability, and good resistance to various corrosion mediums(acid, alkali, salt)and organic solvents.
c. High Impact Resistance
Which is 5 times that of HDPE Pipe, 2 times that of PC pipe and 10 times that of PTFE pipes. which makes the UHMWPE pipe can withstand great water hammer impact when starting up the pump station.
d. High-Pressure Resistance
which is 2 times that of PE100 pipe and 2.5 times that of PE80.UHMWPE pipe can withstand wide fluctuations of water pressure in the pipeline.
e. Environment Protection
The manufacturing and processing of wear-resistant UHMWPE pipe is low carbon, without wasted water, exhausted gas and waste residue, which saves 20% energy compared with the traditional steel pipes.
f. High Flexibility
With High Toughness and elongation of no less than 350%, the UHMWPE pipe and the connection site will not crack when the crust settles which maximally ensures to the supply of water normally.
g. Non-scaling
With a toughness of 0. and a smooth pipe inner wall, it can efficiently avoid scaling without acid cleaning, which save a lot of maintenance cost.
h. Low energy consumption
Its coefficient of friction resistance is 0.009 while that of steel pipe is 0.013. With the same diameter, the flow rate of UHMWPE pipe is large than steel pipe, and with the same flow rate, UHMWPE pipe can save 25% energy.

How to select cost-effective mine tailing pipes?
UHMWPE pipe is the most cost-effective. The ore pulp shall be discharged into the tailing pond to wait for the second use later. The particle size of the refined mortar is generally finer, generally between 50 mesh and 200, which is a good difference in size from the sand. The mortar contains water and belongs to the medium of slurry particles. The first consideration for selection is wear resistance. There are many types of pipes with good wear resistance used in mines, such as ceramic composite pipes, wear-Resistant Rubber-lined pipes, and ultra-high molecular weight Polyethylene Pipes. Choosing the most cost-effective pipeline is not only a matter of wear resistance but also the most suitable one. The most wear-resistant type of rubber-lined pipes is steel-lined wear-resistant rubber, which is generally used in the second stage of beneficiation. When the ore particle size is relatively large, the wear resistance of the ceramic composite pipe is also very strong, and it is used in the third stage. UHMWPE pipes are mainly used in the last process, mainly used to transport mortar, tailings, slurry particles and other media.

UHMW (Ultra High Molecular Weight Polyethylene) is high abrasion and wear-resistant plastic. It is a great thermoplastic that has several applications. Many times polyethylene sheets are also referred to as UHMW sheets. Polyethene’s versatility has made it a popular plastic for many industrial applications requiring durability, low friction, and chemical resistance. UHMW wear strips, chain guides, packaging machinery parts, and marine dock fender pads are typical applications.
We can melt thermoplastics at high temperatures and then cooled to regain their solid form. Thus we can call thermoplastics ‘thermo-softening plastics’. Thermoplastics have a high molecular weight. Intermolecular forces hold the polymer chains together. People can easily break down these intermolecular forces if they apply enough energy.
It explains why this polymer can be molded and melts when heated. People can see the solid melting when they apply enough energy to overcome the intermolecular forces that keep the polymer solid. When we cool it again, it emits heat and re-forms the intermolecular forces, converting it to a solid. As a result, the process is reversible.
The physical properties of thermoplastics differ depending on their melting point and the temperature at which solid crystals form. Furthermore, we can see that they have a rubbery nature between those temperatures. After the polymer is started to melt, we can shape it into various shapes and then re-cool it to produce various products. Nylon, Teflon, Polyethylene, Acrylic Sheets, HDPE pipe fittings, and Polystyrene are common thermoplastics.
UHMW or UHMWPE is an abbreviation for ultra-high molecular weight polyethene. It belongs to the thermoplastic polymer family. This compound has long polymer chains with high molecular weights (around 5-9 million AMU). As a result, UHMW has the greatest molecular density. The presence of this compound, however, is barely distinguishable from HDPE.
The following are important UHMW properties.
UHMW polymer chains are all very long and align the same way. Van der Waal forces connect each polymer chain to the polymer chains. It strengthens the entire structure.
In the presence of a metallocene catalyst, UHMW is produced (HDPE is produced in the presence of a Ziegler-Natta catalyst). The polymerization of the monomer, ethylene, yields UHMW. The polymerization of ethylene forms the base polyethene product because of the manufacturing method; the structure of UHMW differs greatly from that of HDPE.
HDPE stands for High-Density Polyethylene. It is made of a thermoplastic polymer. Compared to other types of polyethene, this material has a high density. HDPE has a density of 0.95 g/cm3 and is recyclable. The polymer chains in this material are packed tightly because the degree of polymer chain branching is very low. As a result, HDPE pipe fittings are relatively hard and have high impact resistance. HDPE can be handled at temperatures as high as 120°C without harm. As a result, HDPE is autoclavable.
HDPE is one of the most uncomplicated recycled plastic materials. These properties determine the applications of HDPE. Some important applications of HDPE include the following.
Both UHMWPE and HDPE are polymerized from ethylene monomers. The primary distinction between UHMW and HDPE is that UHMW has long polymer chains with extremely high molecular weights, whereas HDPE has a high strength-to-density ratio.
