The slurry/tailings conveying wear-resistant pipe is produced with high wear-resistant modified polyethylene raw materials, which is specially designed for the long-distance transportation of solid-liquid two-phase flow such as mine high-concentration slurry, tailings, and mortar. It has strong wear resistance, pressure resistance, and impact resistance. It can withstand long-term high-speed initialization of particles and is not easy to wear and crack.
The inner wall of the pipe is smooth, the friction coefficient is low, there is no scaling, no hanging material, and no blockage, which effectively improves the conveying efficiency and reduces energy consumption. The product is resistant to acid and alkali corrosion and has good flexibility. It can adapt to geological settlement and complex terrain. It adopts hot melt docking or flange connection. The interface strength is high, the seal is reliable and there is no leakage, and the service life is far longer than that of steel pipes.
It is widely used in various types of underground slurry transportation, surface tailings pipelines, paste filling, mud discharge and other systems. It is safe and stable, and has low operation and maintenance costs. It is a key special pipeline for high-efficiency and energy-saving transportation in mines.
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.
