p-CAT™ is a non-invasive, non-destructive, reliable and safe method of performing pipe condition assessment while the system is in operation. It is often described as a pipe screening tool as long sections (many miles) can be quickly tested to identify small localized “hot spots” out of thousands of feet of pipe.
The technology uses a unique patented and proven technique of inverse transient analysis to measure and determine the internal and external condition of pipelines. p-CAT™ can be applied to all metallic, concrete, and AC (asbestos cement) pipes and has been developed through over 17 years of research and development by the University of Adelaide, Australia.
Cost-effective for large- and small-scale pipeline condition assessment. It is able to locate defects in your pipeline, limiting the repairs and replacements to only sections in need of attention, extending the life of your assets, and deferring replacement.
Non-invasive and non-destructive technology. It is suitable for all pressurized pipes and applicable to potable, raw, and wastewater pipes. During the process, it causes no disruption to the pipeline or operation as there is no invasive access to the main.
Average Condition Assessment VS. P-Cat Sub-Sectional Analysis. Average wall thickness measured is simply the average wall condition between two test points. p-CAT’s sub-sectional wall thickness is provided in 30-foot increments over the tested pipe length. This more detailed analysis empowers engineers and owners to prioritize their rehabilitation/replacement budget.
A controlled pressure wave is injected into the pipeline, and monitored by sensors installed on existing pipe fittings. The transient wave experiences partial reflection when it encounters any change in pipeline structure. These changes include known system components and other concerning issues related to pipe deterioration.
The pressure signal is analyzed by examining the response of the transient wave to the pipeline system to determine all anomalies.
