Project Details
DIAM’s aim is to ensure the provision of high quality, sustainable and reliable potable water services to all people in the Sultanate of Oman. Diam’s Mission: Working towards establishing water transmissions and distribution networks and applying systems to manage them efficiently.
The project required the repair of the existing 3LPE coating at locations on the pipeline which runs adjacent to the sea, below sea level, so it is in constant contact with highly (saline) salty water. Since the pipeline carries water under high pressure (25 bar) and considering its age, the end user wanted a solution that would provide long-term protection without having to abrasive clean the substrate in this challenging location.
The Densyl™ Tape System was selected because of its ability to perform under challenging conditions being extremely surface tolerant.
