Anti-corrosion
Polyethylene (PE) is an exceptionally robust and inert material, offering unmatched resistance to a vast array of chemical media. Save for a few potent oxidizing agents, it effortlessly stands up to both soil and water, remaining impervious to corrosive effects.
Secure Connection
Our pipes are predominantly joined through advanced heat fusion butt joints and electrofusion. This seamless integration process ensures that the interface strength not only matches but surpasses the pipe body's own inherent strength.
High Flexibility
Exhibiting a remarkable pipe elongation at break of ≥ 500%, our pipes boast exceptional flexibility. They adeptly manage uneven soil settlement and demonstrate superior seismic performance, ensuring reliability and longevity.
Excellent Impact Resistance
Engineered to perform in harsh low-temperature environments (-20ºC to -40ºC), these pipes resist external impacts robustly, eliminating risks of cracking or other damages.
Exceptional Cracking Resistance
Our pipes exhibit outstanding resistance to rapid *** propagation (RCP) and slow *** growth (SCG). This effectively mitigates the risk of cracking and *** spreading, even under low-temperature conditions or installation damage.
Low Friction Coefficient
Featuring a smooth inner wall and non-adhesive properties, our pipes maintain optimal conveying capacity, minimizing pressure loss within the pipeline to ensure efficient flow.
Product Description:
- Low density, lightweight construction - easy to handle and install.
- Superior corrosion resistance to various chemical mediums.
- Smooth inner wall guarantees strong circulation capacity and efficiency.
- Extended service life: durable for up to 50 years.
- High toughness combined with outstanding seismic resistance.
- Enhanced resistance to slow *** growth (SCG) and rapid *** propagation (RCP).
