Anti-corrosion
Polyethylene (PE) is an incredibly tough and chemically inert material, providing exceptional resistance to a wide range of chemical substances. Apart from a few oxidizing agents, it remains impervious to both soil and water without experiencing corrosive effects.
Secure Connection
Our pipes are primarily joined through heat fusion butt joints and electrofusion. This technique seamlessly integrates the joints with the pipe materials, ensuring the joint integrity surpasses the strength of the pipe itself.
High Flexibility
With a pipe elongation at break of ≥ 500%, our pipes offer extraordinary flexibility. They effectively handle uneven soil settlement and display outstanding seismic performance.
Excellent Impact Resistance
Engineered to excel in low-temperature environments (-20ºC to -40ºC), our pipes withstand external impacts and avoid cracking or other forms of damage.
Exceptional Cracking Resistance
Our pipes showcase extraordinary resistance to rapid *** propagation (RCP) and slow *** growth (SCG). This significantly reduces the likelihood of cracking and *** extension, even in low-temperature scenarios or if installation damage occurs.
Low Friction Coefficient
Featuring a smooth inner wall with non-adhesive properties, our pipes ensure optimal conveying capacity and minimize pressure loss within the system.
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).
