Application of HDPE and PE pipe in mining industry
HDPE plastic pipe is widely used in mining industry due to its unique characteristics. Piping is flexible, wear-resistant, durable and accommodates leak-free joints. They can be used in all kinds of weather and terrain, so they can be adapted to different field environments. They can also be joined together using heated fusion joints, which allows them to be used over long distances.
PE pipes are also often used in the mining industry to ensure safe transportation through excellent chemical resistance.
Pipelines in the mining industry are used to transport process water, mud and tailings. They are also used in solution mining, heap leaching, dust suppression, mine dehydration and decompression.
Reasons for the use of HDPE pipe in mining industry
The biggest incentive to use HDPE pipelines in mining is cost. Low-cost pipelines help reduce overall mining costs. These cost advantages are amplified by the possibility of using HDPE in an all-weather installation, ease of maintenance, and limited risk of incorrect assembly. In addition, the HDPE is strong enough to resist damage caused by pressure changes when handling and transporting fluids during mining. Another important reason why HDPE pipe is used in mining is that it is easy to fuse. For these pipes, modern connection methods are easy to implement and safe. In addition, the joints are strong, kink resistant and easy to maintain. These joints can also resist large temperature fluctuations in extreme temperature climates. As a result, advances in connection methods have increased the use of HDPE pipelines in mining. In contrast, traditional methods are laborious and difficult.
Using HDPE piping in mining also reduces the risk of injury during maintenance, installation, transportation, and demolition. For example, easier connections can prevent injuries that can occur when fuses are moved and operated to release exhaust fumes and smoke.
Advantages of HDPE and PE pipe in mining
Safety and reliability are the most important factors when selecting pipelines for the mining industry. In addition, pipes should be rust-proof, breakproof and corrosion resistant. In addition, many companies are now exploring the use of environmentally friendly pipelines in mining.
Mining involves the use of chemicals, including overreactive and aggressive chemicals. The exact type of chemical depends on what is being mined. They include nitric acid, sulfuric acid and ammonium nitrate, as well as heavy metals such as mercury and lead. Therefore, corrosion resistance of PE and HDPE tubing is critical for any application in the field. Pipelines must be protected from damage caused by these chemicals to prevent fluid loss in transit or even contamination of the product being mined.
PE tubes can be used in mining using low pH acid and high pH caustic solutions. They can be used in harsh chemical mining environments without incurring any additional costs due to damage.
Their structural strength is also advantageous in mining, as it helps prevent structural damage when handling solids and liquids under high pressure.
In addition to being expensive, using metal tubes can be chemically destructive. On the contrary, PE tube is low cost. You don't add unnecessary costs to the mining process. In addition, they have low labor costs when they are installed.
The cost effectiveness of PE tubing in the mining industry is well known. Given their physical strength, corrosion resistance, leak-free joints and reduced maintenance costs, they help reduce the overall cost of mining. In fact, it is estimated that they can serve operations for more than 50 years.
Other benefits achieved by using PE piping during mining include zero allowable leakage. Considering the typical leakage rate of ductile iron is 10 to 20 percent, this is huge.
HDPE pipes are also a good choice for transporting minerals and waste in mines. The HDPE is semi-rigid and can withstand high external loads and pressure surges. In other words, when pressure surges, pipes that are somewhat pliable adjust to prevent damage. This reduces maintenance costs.
HDPE pipes have excellent chemical resistance due to the inherent inert nature of the polyethylene polymer they contain. The wear resistance of HDPE pipeline in PE pipeline system is much better than that of metal pipeline system because of its wear resistance and scour resistance.
HDPE pipes are cost-effective due to their low maintenance costs and leak-free joints. The lifetime of HDPE pipes is conservatively estimated to be between 50 and 100 years.
In addition, HDPE piping can be installed quickly and economically. It's about one-eighth as dense as steel, making it lighter and easier to position.
Whichever you choose, these pipes are weather-resistant and can be used in any environment, regardless of exposure to sun, wind, light and rain. In other words, they can be used even in the harshest weather and climates. This is in addition to being resistant to various chemicals widely used in mining.
