**Anti-corrosion**
Polyethylene (PE) is an exceptionally inert material, showcasing resistance to a vast array of chemical media. Save for a handful of oxidizing agents, it completely nullifies concerns about corrosive impacts from soil and water quality.**Good Connection Security**
Our pipes utilize cutting-edge heat fusion butt joints and electrofusion for connections. This technique seamlessly integrates the joints with the pipe material, ensuring that the interface strength exceeds the strength of the pipe itself.
**High Flexibility**
With an impressive pipe elongation at break of ≥ 500%, our pipes demonstrate remarkable flexibility. They proficiently handle uneven soil settlement and offer outstanding seismic performance.
**Good Impact Resistance**
In low-temperature environments ranging from -20ºC to -40ºC, our pipes perform impeccably. They withstand external impacts, preventing cracks and other damages.
**Good Cracking Resistance**
Featuring exceptional rapid crack propagation (RCP) and slow crack growth (SCG) resistance, our pipes effectively prevent cracking and crack propagation in cold regions and during installation damages.
**Low Friction Coefficient**
The smooth inner wall and non-adhesive properties of our pipes guarantee optimal conveying capacity while substantially reducing pressure loss within the pipeline.
