Polyethylene (PE) is an exceptionally inert material, offering unparalleled resistance to a diverse range of chemical agents. Apart from a few oxidizing substances, it effectively neutralizes concerns about corrosion from both soil and water quality.
Superior Connection Security
Our pipes are primarily connected using heat fusion butt joints and electrofusion. This state-of-the-art technique seamlessly integrates the joints with the pipe material, ensuring that the interface strength exceeds the pipe body strength itself.
Exceptional Flexibility
With an impressive pipe elongation at break of ≥ 500%, our pipes demonstrate extraordinary flexibility. They efficiently manage uneven soil settlement and offer outstanding seismic performance.
Outstanding Impact Resistance
In low-temperature environments ranging from -20ºC to -40ºC, our pipes exhibit flawless performance. They withstand external impacts, preventing cracks and other damages.
Excellent Cracking Resistance
With superior rapid crack propagation (RCP) and slow crack growth (SCG) resistance, our pipes effectively prevent cracking and crack propagation in low-temperature regions and during installation damages.
Low Friction Coefficient for Efficiency
The smooth inner wall and non-adhesive properties of our pipes ensure optimal conveying capacity, significantly reducing pressure loss within the pipeline.

Comprehensive Product Description:
- Low density, lightweight, and easy to handle and install for seamless operations.
- Remarkable corrosion resistance against a variety of chemical media.
- Smooth inner wall ensures powerful circulation capability.
- Extended service life, lasting up to 50 years.
- High toughness combined with superior seismic resistance.
- Enhanced resistance to slow crack growth (SCG) and rapid crack propagation (RCP) for enduring performance.
