Product Description

Our Polyethylene Pipe for Coal Mines represents a breakthrough in pipeline technology. This single-layer solid wall pipe is crafted using our state-of-the-art, self-developed carbon nanotubes (CNT) modified material. By incorporating highly conductive fiber carbon nanotubes (CNT), these pipes surpass traditional carbon black conductive agents, using only 30% of the typical carbon black content. This innovative design results in superior anti-static and flame-retardant properties, exceeding MT181 standard requirements and outperforming conventional carbon black conductive pipelines. Moreover, the long-term hydrostatic performance of our pipelines is significantly enhanced, ensuring exceptional safety and durability for prolonged use.

Product Features

 

Anti-scaling property

Drawing on the revolutionary principle of 'lotus leaf hydrophobicity,' we utilize cutting-edge organic polymers and advanced processing techniques to elevate the water contact angle on the pipe's surface to an impressive 111° (standard control ≥105°). This significantly surpasses the usual polyethylene range of 88°-92°, enhancing the smoothness of the pipeline surface. This improvement diminishes the adsorption of calcium, magnesium ions, and other substances, thereby reducing energy consumption. Moreover, our system blends anti-scaling and antibacterial properties to ensure a truly effective antibacterial pipeline, eliminating issues of non-contact failure between the antibacterial layer and fluid due to scaling. (Water contact Angle: the angle of water droplets on a material's surface, with 90° < water contact Angle < 180° indicating hydrophobicity.)

 

Hydrophobic patency

Compared to traditional plastic pipes, our pipelines feature a significantly smoother inner wall, resulting in lower flow resistance and higher water transmission capacity. The smoothness of our inner walls far surpasses that of conventional polyethylene pipes, addressing the challenge of increased energy consumption in long-term pipe network operations. Specifically designed for the drinking water industry, this pipeline type ensures optimal performance.

 

Anti-bacterial Performance

Incorporating ionic antibacterial agents into the pipe's inner wall, and tested in accordance with JC/T939-2004 'Antibacterial Performance of Antibacterial Plastic Pipes for Construction' by Guangdong Microbiological Analysis and Testing Center, our pipes achieve an antibacterial rate exceeding 99.99% against Escherichia coli and Staphylococcus aureus. This eliminates microorganisms attached to the tube wall, prevents microbial film formation, and ensures a permanent antibacterial effect.

 

Terrain adaptability

Our flexible pipe solutions adapt seamlessly to terrain variations. When under pressure, the inherent flexibility of our plastic pipes minimizes the need for additional fittings and allows them to adjust to terrain settlement, offering exceptional adaptability.

 

Economical and efficient

Our pipes are significantly lighter compared to concrete, galvanized, and steel pipes, facilitating easier handling and installation. Reduced manpower and equipment requirements translate to substantially lower installation costs, making our products an economical choice.

 

Long Service Life
Crafted from polyethylene, our pipes boast a long-term design life, with an estimated service life of up to 50 years under standard working conditions, ensuring long-lasting performance.
