**Anti-corrosion**
Polyethylene (PE) stands as a remarkably inert material, exhibiting exceptional resistance to a wide array of chemical media. Except for a few oxidizing agents, it eliminates concerns about corrosive impacts stemming from soil and water quality.**Good Connection Security**
Our pipes employ cutting-edge heat fusion butt joints and electrofusion techniques for connections. This innovative method ensures the interface strength surpasses that of the pipe itself, providing seamless integration and unrivaled security.
**High Flexibility**
Boasting a pipe elongation at break of ≥ 500%, our pipes exhibit extraordinary flexibility. They effectively manage uneven soil settlement and deliver superior seismic performance, adapting to challenging conditions effortlessly.
**Good Impact Resistance**
In harsh low-temperature environments ranging from -20ºC to -40ºC, our pipes excel, withstanding external impacts to prevent cracks and other damages, ensuring optimal durability.
**Good Cracking Resistance**
With outstanding rapid *** propagation (RCP) and slow *** growth (SCG) resistance, our pipes are engineered to resist *** formation and propagation, particularly in cold regions and during installation.
**Low Friction Coefficient**
The smooth inner walls and non-adhesive properties of our pipes ensure optimal conveying capacity, significantly minimizing pressure loss within the pipeline for efficient operation.
