A large mining project needs to lay 6,500 meters of drainage and slag discharge pipes for discharging mine groundwater, slag wastewater and waste residue. The mine has complex terrain and severe corrosive environment, limited construction conditions and lack of large construction equipment. The original ordinary steel pipes suffered from serious corrosion, wear and blockage after 4 years of use. Frequent damage caused interruption of mine production, and the annual replacement and maintenance cost is high. The customer urgently needs a wear-resistant, corrosion-resistant, convenient construction pipeline solution that meets international standards and can be directly imported in bulk.
Combined with the complex mine working conditions and drainage and slag discharge needs, we customized HDPE drainage and slag discharge pipes with specifications DN160-DN400mm and pressure class PN16-PN25, with a total length of 6,500 meters, matched with HDPE wear-resistant fittings, large-diameter valves and anti-blockage interfaces. The products are made of PE100 special wear-resistant raw materials added with wear-resistant agents, with wall thickness 10.0-25.4mm, ring stiffness ≥12kN/m², excellent wear resistance, friction coefficient 0.008, working pressure 1.6-2.5MPa, resistant to acid, alkali and heavy metal corrosion. They comply with international mining engineering standards and have passed CE certification, can be directly exported, and adapt to the harsh mine use environment.
“The mine environment is harsh. Pipes have to withstand the scouring of slag and wastewater every day, as well as complex terrain and corrosive soil. The previous steel pipes often wear, block and damage, needing to be replaced several times a year, not only wasting costs but also affecting the normal production of the mine. After choosing Henan Lukuang HDPE drainage and slag discharge pipes, all these problems have been completely solved. The pipes have excellent wear and corrosion resistance, no damage or blockage after more than 1 year of use, can withstand high-pressure impact, no pipe bursting risk, and drainage and slag discharge efficiency has been greatly improved. Moreover, the pipes are lightweight and easy to construct, no large equipment required, adapting to the complex mine terrain. 6,500 meters of pipes were laid in 20 days, saving 40,000 yuan in maintenance costs per year, fully meeting international mining standards, and the import process is also worry-free. It is a reliable guarantee for mine production!” ——Person in charge of mine engineering
Wear and corrosion resistance, impact resistance, adapting to complex mine working conditions, anti-blockage, high drainage and slag discharge efficiency, convenient construction without large equipment, service life of more than 50 years, reducing replacement and maintenance costs, in line with international mining standards. We provide foreign trade import services throughout the process to ensure the normal production of mines.
6,500 meters of pipes were laid in 20 days, adapting to the complex mine terrain without any construction problems; drainage and slag discharge efficiency improved by 50%, completely solving the problem of pipe blockage and damage, ensuring continuous and stable mine production without production stagnation caused by pipe problems; saving 40,000 yuan in pipe replacement and maintenance costs per year. The wear and corrosion resistance of the pipes has been verified by actual working conditions. The customer has placed 2 additional bulk orders and listed our products as the first choice for mine pipe procurement.
