Anti-corrosion
Polyethylene (PE) is a remarkably inert material, boasting resistance to a broad spectrum of chemical media. Except for a few oxidizing agents, it completely mitigates concerns about corrosive effects from soil and water quality.Good Connection Security
Our pipes are predominantly connected via heat fusion butt joints and electrofusion. This technique integrates the joints seamlessly with the pipe material, ensuring that the interface strength surpasses the strength of the pipe body itself.
High Flexibility
With a pipe elongation at break of ≥ 500%, our pipes exhibit remarkable flexibility. They adeptly handle uneven soil settlement and offer superior seismic performance.
Good Impact Resistance
In low-temperature environments ranging from -20ºC to -40ºC, our pipes perform flawlessly. They resist external impacts, preventing cracks and other damages.
Good Cracking Resistance
Possessing excellent rapid crack propagation (RCP) and slow crack growth (SCG) resistance, our pipes effectively avert cracking and crack propagation in low-temperature areas and during installation damages.
Low Friction Coefficient
The smooth inner wall and non-adhesive properties of our pipes ensure optimal conveying capacity while significantly reducing pressure loss within the pipeline.
