Repairing A Suspended Pipe Within 30 Minutes With HYMAX Permanent Repair Sleeve

In the picturesque village of Arzacq-Arraziguet in southwestern France, a critical water pipeline repair showcased the efficiency of modern tools and techniques. SATEG, a subsidiary of SAUR, oversees the water distribution network for over 35,000 subscribers across nearly 200 municipalities in the Pau region. Their network comprises 1,200 km of cast iron, asbestos cement, and PVC pipes. When a leak sprung on a DN200 steel pipe suspended from a bridge, it presented unique challenges, including restricted access and high-pressure flow at 15m³/hour under 11 bars.

To address the issue swiftly and safely, SATEG opted for the Versa® permanent repair sleeve by HYMAX®. Unlike traditional methods requiring welding—which was impractical due to the pipe's location and active water flow—the Versa sleeve offered a reliable, non-invasive solution. Lightweight and equipped with a hydraulic pressure-assisted gasket, the sleeve was easy to install, sealing the leak within 30 minutes. Its dynamic design accommodates deflections caused by traffic vibrations and temperature changes, ensuring durability in demanding conditions.

Sébastien Picollo, SATEG's operations manager, praised the sleeve’s simplicity and performance compared to older, rigid models. The product’s adaptability to various pipe materials and sizes reduced downtime, minimized inventory needs, and enhanced worker safety. This successful repair not only restored water service to nearby farms but also underscored the importance of innovation in maintaining critical infrastructure efficiently.
