Advanced Anti-corrosion Technology
Polyethylene (PE) is an exceptionally inert material, showcasing incredible resistance to a wide array of chemical media. Apart from a few oxidizing agents, it provides outstanding protection against corrosive effects from soil and water quality.Superior Connection Security
Our pipes are primarily connected through advanced heat fusion butt joints and electrofusion. This method seamlessly integrates the joints with the pipe material, ensuring that the interface strength surpasses that of the pipe body itself.
Remarkable High Flexibility
With a pipe elongation at break of ≥ 500%, our pipes demonstrate exceptional flexibility. They efficiently manage uneven soil settlement and deliver superior seismic performance.
Excellent Impact Resistance
In low-temperature environments ranging from -20ºC to -40ºC, our pipes perform impeccably. They withstand external impacts, preventing cracks and other damages.
Exceptional Cracking Resistance
With outstanding rapid crack propagation (RCP) and slow crack growth (SCG) resistance, our pipes effectively prevent cracking and crack propagation in low-temperature areas and during installation damages.
Low Friction Coefficient for Optimal Flow
The smooth inner wall and non-adhesive properties of our pipes ensure optimal conveying capacity while drastically reducing pressure loss within the pipeline.
