Anti-corrosion
Polyethylene (PE) is an exceptionally robust and inert material, offering superior resistance to a vast array of chemical media. Except for a few oxidizing agents, it stands resiliently against both soil and water, effectively warding off corrosive effects.
Secure Connection
Our pipes are predominantly joined through heat fusion butt joints and electrofusion. This advanced process seamlessly integrates the joints and pipe materials, ensuring that the interface strength surpasses the pipe body's inherent strength.
High Flexibility
Exhibiting an impressive pipe elongation at break of ≥ 500%, our pipes boast remarkable flexibility. They adeptly manage uneven soil settlement and offer superior seismic performance, ensuring durability in various conditions.
Excellent Impact Resistance
Engineered to excel in low-temperature environments (-20ºC to -40ºC), these pipes resist external impacts and demonstrate exceptional durability, preventing cracking or other damages.
Exceptional Cracking Resistance
Our pipes showcase incredible resistance to rapid *** propagation (RCP) and slow *** growth (SCG), effectively mitigating the risk of cracking and *** spreading. This ensures reliability 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, minimizing pressure loss within the pipeline for efficient performance.
Product Description:
