Pipes and POWER-LOCK® Bends in PVC-A
The sustainable and innovative solution for water transport, simple and quick to install, reliable and safe without the need of maintenance.
PVC-A Characteristics
PVC-A refers to a polymer alloy that originated in 1995 through collaboration between the English organization North West Water and the research institute Pipeline Development Ltd.
This innovative polymer alloy (PVC-A), combines the strength of PVC-U (unplasticized polyvinyl chloride) with the flexibility of polyethylene (PE). By carefully selecting and blending these materials, we created a new generation of polymer alloy that meets the needs of water industry.
The combination of polyethylene’s ductility and robustness with PVC-U’s high strength results in a new product with excellent performance characteristics, offering both toughness and durability.
Their high-resistance to breakage, even under point loads, combined with a high yield strength, ensures superior performance compared to other plastic materials available in the market
The advantages of the VDA® system
- Resistant to crack propagation: The main cause of breakage during installation and laying operations.
- Maximized flow rate: Reduced pressure drop, and optimized plant management costs thanks to the larger internal diameter compared to other pipes with the same PN.
- Simple and fast installation: Greater maneuverability and safety on-site due to the reduced weight compared to other pipes of the same diameter and PN. Reduced installation times and costs thanks to the quick and reliable jointing technology.
- Guaranteed hydraulic seal: FORSHEDA POWER-LOCK® gasket pre-inserted during the tube flaring phase when hot.
- Corrosion-resistant: No risk of leakage along the network compared to traditional metal pipes.
