Product Description

Introducing our groundbreaking Polyethylene Pipe for Coal Mines, a marvel of modern engineering and innovation. This single-layer, solid-wall pipe harnesses the power of our exclusive carbon nanotube (CNT) modified material. By substituting traditional carbon black conductive agents with high-conductive CNT fibers, we achieve unparalleled performance, adding only 30% of the conventional carbon black while surpassing all MT181 standard requirements. Our pipe showcases superior anti-static and flame-retardant properties, ensuring enhanced safety and reliability. Notably, the pipeline's long-term hydro hydraulic performance far exceeds that of traditional alternatives, promising a more secure, durable, and efficient pipeline system designed for long-term use. Experience the epitome of innovation and longevity with Shandong Donghong Pipe Industry Co., Ltd.

Product Features

 

Anti-scaling property

Drawing inspiration from the 'lotus leaf hydrophobic' principle, our advanced organic polymers and specialized processes elevate the water contact angle on the pipeline surface to an impressive 111° (standard control ≥105°). This far surpasses the 88°-92° range of ordinary polyethylene, significantly enhancing surface smoothness. Consequently, the adsorption of calcium, magnesium ions, and other substances in water is drastically reduced, lowering pipeline energy consumption. This superior anti-scaling property ensures a genuine antibacterial effect, preventing non-contact failures between the antibacterial layer and the fluid caused by scaling. (Water contact angle: The angle at which a water droplet contacts the material's surface; a 90° < water contact angle < 180° indicates hydrophobic properties.)

 

Hydrophobic Patency

Boasting a smoother inner wall compared to conventional plastic pipes, our product minimizes flow resistance and maximizes water transmission capacity. The inner wall's enhanced smoothness, superior to traditional polyethylene pipes, addresses the issue of increased energy consumption during prolonged pipe network operations. Specifically designed for the drinking water industry, our pipeline offers unparalleled performance.

 

Anti-bacterial Performance

We incorporate an ionic antibacterial agent into the pipe's inner wall. Based on the JC/T939-2004 standard for 'Antibacterial Performance of Antibacterial Plastic Pipe for Construction,' tested by the Guangdong Microbiological Analysis and Testing Center, our product achieves an antibacterial rate of >99.99% against Escherichia coli and Staphylococcus aureus. This prevents microorganism attachment and surface microbial film formation, ensuring a permanent antibacterial effect.

 

Terrain Adaptability

Our pipes are designed with pressure resilience and flexibility in mind. The flexible laying capability minimizes the need for additional fittings and adapts to terrain changes during settlement, ensuring seamless operation.

 

Economical and Efficient

Lighter than concrete, galvanized, and steel pipes, our product is easy to handle and install, significantly reducing manpower and equipment needs. This translates to greatly lowered installation costs for your projects.

 

Long Service Life
Crafted from high-quality polyethylene, our pipes are designed for long-term durability, with an extrapolated service life of 50 years under normal working conditions.
