Anti-corrosion
Polyethylene (PE) is an exceptionally stable material, exhibiting resistance to an extensive range of chemical media. Except for a few oxidizing agents, it completely negates concerns about corrosive effects from soil and water quality.Good Connection Security
Our pipes are primarily joined using advanced heat fusion butt joints and electrofusion techniques. This method seamlessly integrates the joints with the pipe material, ensuring that the interface strength exceeds the pipe body's strength.
High Flexibility
With a pipe elongation at break of ≥ 500%, our pipes demonstrate extraordinary flexibility. They expertly manage uneven soil settlement and provide exceptional seismic performance.
Good Impact Resistance
In low-temperature environments ranging from -20ºC to -40ºC, our pipes perform superbly. They withstand external impacts, preventing cracks and other damages.
Good Cracking Resistance
Featuring outstanding 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
The smooth inner wall and non-adhesive properties of our pipes ensure optimal conveying capacity while greatly minimizing pressure loss within the pipeline.
