Slurry conveying and tailings conveying wear-resistant pipes are specially designed for high-concentration, high-wear, and strong-corrosion mine solid-liquid mixed conveying conditions. They are extruded and molded with ultra-high molecular weight polyethylene or modified wear-resistant composites. They have strong anti-initialize, wear resistance, and anti-aging properties. They can withstand high-speed initialization of sand, tailings, slag and other particles for a long time and are not easy to break or burst the pipe.
The inner wall of the pipe is smooth, the resistance is small, there is no scaling, no hanging material, and it is not easy to block, which greatly improves the transportation efficiency of pulp and tailings, and reduces energy consumption and maintenance costs. The overall flexibility is good, high pressure resistance, acid and alkali corrosion resistance, and it is connected by hot melt butt or flange. The interface has high strength, strong sealing, and no leakage. It can adapt to the complex terrain of the mine, long-term vibration and high and low temperature changes, and the service life far exceeds that of traditional steel pipes and cast iron pipes.
It is widely used in underground slurry transportation, surface tailings transportation, filling pipeline, tailings cementation transportation, mud discharge and other systems of various metal mines, non-metallic mines, and coal mines. It is a special wear-resistant transportation pipeline with high efficiency, stability and energy saving.
Super wear-resistant performance, suitable for high-wear slurry transportation
POE toughened and modified special formula, the wear resistance is more than 10 times that of ordinary HDPE, and it is resistant to erosion and wear of ore and tailings particles;
Excellent impact toughness, resistant to particle impact damage
Resistant to high-speed slurry impact, stone impact, and not brittle in low-temperature environments;
The inner wall is super smooth, not easy to scale and block the pipe, and the transportation efficiency is high
The inner wall roughness is ≤0.006mm, and the slurry and tailings are not easy to adhere and deposit, reducing pipe blockage and transportation resistance;
Resistant to strong corrosion, suitable for acidic/alkaline tailings media
Resistant to corrosion by acids, alkalis, salts, and slurry chemical media, and resistant to long-term erosion by mine wastewater and tailings water;
Resistant to environmental stress cracking, stable long-term mining conditions
Environmental stress cracking resistance ESCR ≥ 12000h, adaptable to mountainous subsidence, geological displacement, and day and night temperature difference;
Good flexibility, suitable for laying in complex terrain of mines
It can be flexibly bent and coiled to adapt to the mine pipe network layout with undulating mountains, many bends and large drops;
A variety of connection methods are designed to address wear-resistance issues to prevent seepage and leakage.
Paired with Kangyu's unique high-pressure wear-resistant component design connection and low-pressure pipe integrated connection, the interface strength is higher than the pipe body to prevent slurry and tailings from leaking and polluting the environment;
Light weight, low installation and construction costs
The dead weight of the pipe is only 1/7 of the wear-resistant steel pipe and 1/10 of the cast stone pipe. It is easy to transport and greatly reduces the labor and machinery costs of mine installation;
Antistatic and flame resistant to meet mine safety requirements
Antistatic and flame retardant modifications can be customized to suit explosion-proof and anti-static working conditions in underground and open-pit mines;
Super long service life and low comprehensive operating costs
The laboratory proportion simulation of mining slurry working conditions provides the optimal wear-resistant pipeline solution, which requires no anti-corrosion, no lining replacement, and no maintenance during use.
