Versatility Unleashed
Our universal black pipes aren't just pipes; they're versatile solutions ready to tackle a multitude of applications:
Above Ground: Ideal for potable water(*)
Below Ground: Perfect for a diverse range of applications, including hydroelectricity schemes, geothermal pipework, buried fire protection ring mains, sewerage systems, rainwater drainage, fish farming (cage frames), marine outfalls, irrigation systems, and ducting for electricity cabling in renewable energy projects.
Our universal black pipes seamlessly come together using industry-standard electrofusion and butt-fusion welding techniques. Plus, we offer a unique range of Redman™ hydraulic compression fittings and compatible mechanical fittings.

Anti-scaling property
Drawing on the principle of 'lotus leaf hydrophobic', our PEX water pipes utilize organic polymers and special processes to elevate the water contact angle on the pipeline surface to 111° (standard control ≥105°), significantly surpassing ordinary polyethylene's 88°-92°. This enhancement improves surface smoothness, reduces calcium and magnesium ion adsorption, and lowers energy consumption. The anti-scaling and antibacterial properties synergize to ensure genuine antibacterial effectiveness, preventing non-contact failures between the antibacterial layer and fluid caused by scaling. (Water contact angle: the angle of water droplets on the material surface, 90° < water contact angle < 180° indicates hydrophobicity.)Hydrophobic patency
Compared to conventional plastic pipes, our PEX water pipes offer a smoother inner wall, reduced flow resistance, and heightened water transmission capacity. The inner wall smoothness exceeds that of traditional polyethylene pipes, addressing the issue of increased energy consumption during prolonged pipe network operations. Specifically designed for the drinking water industry.
Anti-bacterial Performance
Our PEX water pipes incorporate ionic antibacterial agents on the inner wall. Tested by Guangdong Microbiological Analysis and Testing Center per JC/T939-2004 standards, the antibacterial rate against Escherichia coli and Staphylococcus aureus exceeds 99.99%. This ensures the elimination of microorganisms on the tube wall, prevents microbial film formation, and offers a permanent antibacterial effect.
Terrain adaptability
The flexibility of our PEX water pipes allows for adaptive laying under pressure, reducing the need for additional fittings and accommodating terrain adjustments during settling.
Economical and efficient
Lighter than concrete, galvanized, and steel pipes, our PEX water pipes are easy to handle and install. This results in significantly reduced installation costs due to lower manpower and equipment requirements.
Long Service Life
Crafted from durable polyethylene, our PEX water pipes are designed for a long-term service life, with an estimated operational lifespan of 50 years under normal working conditions.
