Anti-corrosion
Polyethylene (PE) is an exceptionally inert material, providing unmatched resistance against a vast range of chemical media. With the exception of a few oxidizing agents, PE fully mitigates any concerns related to corrosive impacts from soil and water quality.
Good Connection Security
Our state-of-the-art pipes utilize heat fusion butt joints and electrofusion, which seamlessly integrate the joints with the pipe material itself. This method ensures that the interface strength is superior to the pipe body strength, guaranteeing exceptional connection security.
High Flexibility
Boasting a pipe elongation at break of ≥ 500%, our pipes are designed for unparalleled flexibility. They adeptly manage uneven soil settlement and offer top-notch seismic performance.
Good Impact Resistance
Engineered to excel in low-temperature environments from -20ºC to -40ºC, our pipes deliver flawless performance. They withstand external impacts effectively, preventing cracks and damages.
Good Cracking Resistance
With exceptional resistance to rapid crack propagation (RCP) and slow crack growth (SCG), our pipes are designed to prevent cracking and crack propagation, even in low-temperature areas and during installation damages.
Low Friction Coefficient
Featuring a smooth inner wall and non-adhesive properties, our pipes ensure optimal conveying capacity and significantly reduce pressure loss within the pipeline.
Product Description:
- Low density, lightweight, and effortlessly manageable for easy installation.
- Corrosion resistance against a broad range of chemical media.
- Smooth inner wall guarantees superior circulation capability.
- Extended service life, reaching up to 50 years.
- High toughness paired with excellent seismic resistance.
- Enhanced resistance to slow crack growth (SCG) and rapid crack propagation (RCP).
