Water hammer is a hydraulic phenomenon that occurs when a flow of water in a pipeline suffers a sudden interruption, such as the rapid closure of a valve or the sudden stop of a pump. This event generates pressure waves that can cause significant damage to pipes and fittings, reducing the service life of the pipeline system. In this context, fittings made of PVC-O (oriented polyvinyl chloride) have emerged as an effective and reliable solution thanks to their exceptional strength and unique properties.

PVC-O is an improved version of traditional PVC, obtained through a molecular orientation process. This process rearranges the molecules of the material and makes PVC-O fittings stand out from other materials thanks to their:

• High mechanical strength
  PVC-O is significantly more resistant to pressure than conventional PVC and other plastic materials. Its oriented molecular structure allows it to withstand sudden pressure peaks without deformation or rupture, which is essential to mitigate water hammer damage.
• Enhanced Ductility
  The ductility of PVC-O acts as a natural shock absorber against pressure waves generated by water hammer. This absorption capacity reduces the risk of cracking and prolongs the service life of piping systems.
• Installation Safety
  PVC-O fittings are lightweight compared to materials such as concrete or ductile iron. This makes them easier to handle and install, ensuring a safer fit and minimizing the risk of failure due to faulty connections, which could exacerbate the effects of water hammer.
• Fatigue Resistance
  Piping systems are subject to constant pressure variations. PVC-O stands out for its ability to withstand these repeated changes, preventing the progressive deterioration that can increase vulnerability to water hammer.

For these reasons, ecoFITTOM® PVC-O fittings are ideal for potable water supply systems, irrigation, reuse, industry, fire-fighting and impulsion networks, among other uses where water hammer can be a recurring problem. In field tests, PVC-O pipes and fittings have shown a significant reduction of damages related to pressure surges, improving system reliability.

PVC-O represents a key technological breakthrough in water pipelines, offering a robust and efficient solution to mitigate the destructive effects of water hammer. Its superior strength, ductility and durability properties not only ensure system integrity, but also generate long-term economic and environmental benefits.

Opting for ecoFITTOM® PVC-O fittings is a strategic investment for any water infrastructure, ensuring reliable performance against the demands of modern water conveyance systems.
