Bell and Spigot Over band
Western Port Water
Repair the protective coating on the bell and spigot joins of the main supply pipeline to Phillip Island.
Phillip Island, Victoria, Australia
Western Port Water is a key customer engaging QSW for various works throughout their reservoir and distribution systems. A breakdown of the protective coating on the bell and spigot joins of the main supply pipeline to Phillip Island lead to serious localised corrosion. Two options were considered, replace the pipe line or cut out and replace the joins.
An alternate option was developed involving the fabrication of a two piece over-band which would be welded over the existing join with no disturbance to water supply and the existing join.This solution is quick to install and has successfully extended the service life of the pipe line which was otherwise in good condition.
