PIPELINE CONDITION ASSESMENT(p-CAT)
CRITICAL ENVIRONMENTS
The deteriorating state of water infrastructure can result in pipeline failures, emergency repairs, reduced reliability and economic loss.
The application and use of innovative pipeline technologies has become more critical as expectations and goals associated with infrastructure expand. By leveraging condition assessment technologies and turning data into actionable results, utilities can assess risk and prioritise assets in need of rehabilitation or replacement.
p-CATTM is a non-invasive, non-destructive technology for performing pipe condition assessment while the system is in operation.
p-CATTM can determine remaining wall thicknesses over long sections (many kilometres) of pipeline as well as detecting and locating defects such as air and gas pockets, internal blockages and restrictions, unknown connections, pipe material changes and cement matrix loss from metallic, concrete and AC pipes.
p-CATTM works by analysing the partial reflection of a small, controlled transient signal that is injected into the pipeline. The signal is monitored and recorded by sensors that are temporarily installed on existing pipe fittings. The transient wave experiences partial reflection when it encounters any change in pipeline structure, including both known features of the system as well as other issues related to pipe deterioration.
• No risk of water contamination
• No requirement for mains shutdown
• Locating anomalies with +/- 10 m precision
• No loss of invasive equipment in the pipeline
• Suitable for all metallic, concrete and AC pipes
• Determining remaining thicknesses of pipe wall to 0.2 mm accuracy
