Anti-corrosion
Polyethylene (PE) is an exceptionally robust and inert material, offering resistance to a vast array of chemical media. Aside from a few oxidizing agents, it stands up effortlessly to both soil and water without succumbing to corrosive effects. This makes it a highly reliable choice for various applications.
Secure Connection
Our pipes are predominantly joined through advanced heat fusion butt joints and electrofusion methods. This seamless integration ensures that the joint strength exceeds the strength of the pipe body itself, delivering unparalleled connection security.
High Flexibility
Exhibiting an impressive pipe elongation at break of ≥ 500%, our pipes boast exceptional flexibility. They adeptly manage uneven soil settlement and exhibit superior seismic performance, making them ideal for dynamic environments.
Excellent Impact Resistance
Specifically designed to perform in low-temperature environments ranging from -20ºC to -40ºC, these pipes resist external impacts and are not prone to cracking or other forms of damage, ensuring longevity 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 in the event of installation damage.
Low Friction Coefficient
Featuring a smooth inner wall and non-adhesive properties, our pipes maintain optimal conveying capacity. This design minimizes pressure loss within the pipeline, ensuring efficient and reliable performance.
Product Description:
- Our pipes are characterized by low density, lightweight properties, making them easy to handle and install.
- They offer robust corrosion resistance to various chemical media, ensuring durability and reliability in diverse conditions.
- The smooth inner wall ensures strong circulation capacity, maintaining optimal flow rates.
- Designed for durability, our pipes offer a long service life of up to 50 years, providing long-term reliability.
- High toughness coupled with excellent seismic resistance makes our pipes ideal for dynamic environments.
- Enhanced resistance to slow *** growth (SCG) and rapid *** propagation (RCP) ensures superior performance and reliability.
