p-CAT™ Nexus
Is a non-invasive, non-destructive technology for performing pipe condition assessment. p-CAT™ Nexus 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 matric loss from metallic, concrete and AC pipes.
p-CAT™ Nexus 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. p-CAT™ Nexus 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™ Nexus is the most comprehensive and advanced solution for long distance pipelines.
