Mine filling wear-resistant pipeline is specially designed for mine underground filling, tailings transportation, mud discharge and other harsh working conditions. It is made of high wear-resistant and high-strength modified polyethylene raw materials and has excellent wear resistance, corrosion resistance and impact resistance. It can withstand high concentration of particles initializing and wear for a long time.
The inner wall of the pipe is smooth and smooth, without scaling or blockage, effectively reducing the conveying resistance and improving the filling efficiency. The overall flexibility is good, high pressure resistance and aging resistance. It adopts flange connection or hot melt docking, which has strong sealing and no leakage. It can adapt to complex terrain and vibration conditions in mines. The service life far exceeds that of traditional steel pipes and cast iron pipes.
Widely used in metal mines, non-metal mines, coal mine underground filling system, tailings cementation filling, mud transportation, tailings discharge and other fields, is a mine green filling, energy-saving, stable and reliable special wear-resistant pipeline.
Ultra-high wear resistance, suitable for flushing with high-concentration filling slurry
POE's special toughened and wear-resistant formula resists high-speed erosion of aggregates, sand, and cement. Its wear resistance is more than 10 times that of ordinary HDPE, and it is resistant to the erosion and wear of ore and tailings particles.
Strong and impact-resistant, resistant to impact damage of filled aggregates
The elongation at break is ≥850%, and it has excellent toughness. It can withstand the impact of coarse-grained aggregates and high-voltage pulse impacts, and it will not be brittle or chipped in low-temperature environments.
The inner wall is smooth and has low resistance to prevent the filling material from adhering to the pipe and blocking the pipe.
The inner wall roughness is ≤0.006mm, and the slurry has good fluidity and is not easy to scale on the wall, reducing the probability of pipe blockage and improving filling and conveying efficiency.
Resistant to acid and alkali corrosion, suitable for complex working conditions of filling media
It can withstand the corrosion of mine filling water, cementitious materials and slag media. It will not age or peel off during long-term transportation, and it can adapt to the humid environment underground.
Resist stress cracking and adapt to mine geological deformation
It has excellent environmental stress cracking resistance, can cope with underground settlement, surrounding rock displacement, and pipeline stress changes, and has stable long-term operation without cracking.
Good flexibility, adaptable to complex underground pipeline layout
The pipe has good flexibility, and the coiled pipe can be customized according to the working conditions and can be laid in a bend. It is suitable for scenarios with many underground bends, large drops, and limited space, and reduces the use of elbow pipe fittings.
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.
