Impressive Anti-Corrosion Properties
Polyethylene (PE) is a remarkably durable and inert material, providing resistance against a wide range of chemical media. Except for a few oxidizing agents, it withstands soil and water contact without experiencing corrosive effects, ensuring longevity and stability.
Secure and Robust Connection
Our pipes are predominantly joined through heat fusion butt joints and electrofusion. This advanced process seamlessly integrates the joints with the pipe material, ensuring the interface strength exceeds the strength of the pipe itself, delivering a secure and lasting connection.
Exceptional High Flexibility
With a pipe elongation at break of ≥ 500%, our pipes offer superior flexibility, adeptly managing uneven soil settlement and providing outstanding seismic performance, ensuring reliable operation under various conditions.
Superior Impact Resistance
Engineered to excel in low-temperature environments (-20ºC to -40ºC), our pipes withstand external impacts without cracking or damage, ensuring reliable performance even in harsh conditions.
Outstanding Cracking Resistance
Our pipes exhibit excellent resistance to rapid *** propagation (RCP) and slow *** growth (SCG), effectively minimizing the risk of cracking and *** spreading, even in low-temperature scenarios or when installation damage occurs.
Low Friction Coefficient for Enhanced Efficiency
Featuring a smooth inner wall and non-adhesive properties, our pipes maintain optimal conveying capacity while minimizing pressure loss within the pipeline, ensuring efficient and cost-effective operation.
