The Pipepod Hydrostatic™
The system operates by using a unique cabling technique for long distance pipe leak detection without the requirement of water flow within a pipeline.
The Pipepod Hydrostatic leak locator system
Internal acoustic technology is fast becoming the most reliable technique of accurately tracing leaks on all material pipelines.
The Pipepod Hydrostatic™ is a failsafe for all new pipe installation projects by incorporating the non-degradable Pipeline™ cable into the pipeline installation process. This in turns allows the contractor to have the capability of pulling technology through the pipeline not only in the event of a failed hydrostatic test, but also for future use over the preceding years.
The Hydrostatic system is designed for pulling through a unique capsule and recording acoustic patterns within a fully pressurised pipe at up to 16 bar test pressure.
Pipepod Hydrostatic™ System Configuration
The system also records cable distance data for accurate leak identification to be located along the buried pipe
System Set up
The delivery and receiver chambers are installed onto 2 DN80 valves spaced up to a distance of 1000 metres; these may be strategic risers, future fire hydrants or air release valve points. A hydrophone capsule (Pipepod™) is fitted to the Pipeline™ cable, the capsule is powered up and the acoustic recording begins.
The 2 isolation valves are opened in sequence and the Pipepod™ capsule is drawn through the pipeline utilising the manual winch system until it reaches the exit valve.
The receiving chamber is then depressurised and the capsule removed for data download.
The recorded data is then analysed in a controlled environment to determine any acoustic interest detected. The distance can then be calculated from the entry to exit point to determine accurate leak location.
During a leakage survey several leaks can accurately be identified on a pipeline, and with one single leakage sweep of the technology. Once the pipeline has been repaired and the testing is successful, the Pipeline™ cable can be removed and reutilised on other projects, or alternatively a secondary wire is pulled through during a survey, and remains in the pipeline as an ongoing technology insertion system.
The Pipeline™ is highly recommended in high risk areas for example under rivers or train crossings.
This product is a must for all pipeline installation contractors, and offers a failsafe method for accurate leak detection in existing and newly-installed mains. This unique system offers the contractor a full leakage sweep service after pipelines have been installed, backfilled and reinstated.
