Anti-corrosion
Polyethylene (PE) is an exceptionally robust and inert material, offering outstanding resistance to a vast array of chemical media. Apart from a few oxidizing agents, it effortlessly withstands both soil and water without succumbing to corrosive effects.
Secure Connection
Our pipes are predominantly joined through heat fusion butt joints and electrofusion. This process seamlessly integrates the joints and pipe materials, ensuring that the interface strength surpasses the pipe body's own strength.
High Flexibility
Exhibiting a pipe elongation at break of ≥ 500%, our pipes boast exceptional flexibility. They adeptly manage uneven soil settlement and exhibit superior seismic performance, ensuring resilience in various conditions.
Excellent Impact Resistance
Designed to perform in low-temperature environments (-20ºC to -40ºC), these pipes resist external impacts and are not prone to cracking or other damages, ensuring durability and reliability.
Exceptional Cracking Resistance
Our pipes demonstrate outstanding resistance to rapid *** propagation (RCP) and slow *** growth (SCG). This effectively mitigates the risk of cracking and *** spreading, even in low-temperature conditions or if installation damage occurs.
Low Friction Coefficient
With a smooth inner wall and non-adhesive properties, our pipes maintain optimal conveying capacity and minimize pressure loss within the pipeline, ensuring efficient performance.
Product Description:
- Low density, lightweight, and easy to handle and install.
- Corrosion resistance to various chemical mediums.
- Smooth inner wall, ensuring strong circulation capacity.
- Long service life: up to 50 years.
- High toughness and excellent seismic resistance.
- Enhanced resistance to slow *** growth (SCG) and rapid *** propagation (RCP).
