Pipeline Inspection & Assessment (PIA) ensures pipeline infrastructure’s safety, reliability, efficiency, and longevity by identifying existing or potential defects, leaks, or weaknesses—using data-driven techniques to inform proactive maintenance, risk mitigation, and asset management decisions.​

p-CAT™ Nexus is a non-invasive, non-destructive technology for performing pipe condition assessment while the system is in operation. p-CAT™ Infinity uses the same technology but provides utilities with a lower resolution outcome.

p-CAT™ Nexus and p-CAT™ Infinity can both 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.

They work 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.

p-CAT™ Nexus and p-CAT™ Infinity can be applied on any pressurised fluid filled pipeline carrying potable, raw or wastewater and saves on costs by locating defects within the pipeline and limiting repairs and replacements to only the sections in need of attention. To date, p-CAT™ is the most comprehensive and advanced solution for long distance pipelines.
