pipeline condition assessment technology

p-CAT detects wall thickness, pipe material changes, blockages and gas pockets

Pipeline Condition Assessment TechnologyThe low-cost solution for non-invasive and

non-destructive pressure pipeline condition assessment

COST-EFFECTIVE FOR LARGE- AND SMALL-SCALE PIPELINE CONDITION ASSESSMENTp-CAT 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 TECHNOLOGYp-CAT is suitable for all water and wastewater pressurized pipelines. During the process, it causes no disruption to the pipeline or operation as there is no invasive access to the main.

AVERAGE CONDITION VS. SUB-SECTIONAL CONDITIONAverage wall thickness measured is simply the average wall condition between two test points.

Sub-sectional wall thickness is determined by separating the pipe section between two test points into sections down to 30 ft.

This more detailed analysis provided by p-CAT empowers engineers and owners to prioritize their rehabilitation/replacement budget.

What is p-CAT?• p-CAT is a non-invasive, non-destructive,

reliable and safe method of performing pipe condition assessment while a 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 pipes, concrete and AC (asbestos cement). It has been developed through over 17 years of research and development by the University of Adelaide, Australia.

p-CAT is suitable for all metallic, non-reinforced concrete and AC pipes.

HOW DOES p-CAT WORK?

A controlled pressure wave is injected into the pipeline and moni-tored 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 compo-nents 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.

p-CAT analysis uses two main techniques:

• Sub-Sectional Pipeline Condition Assessment Assessing the level of pipe deterioration in a sub-section with resolutions down to 30 feet.

• Localized Fault Detection Identifies and provides analysis of significant anomalies such as gas pockets, blockages, the sealing status of valves and unknown pipeline features.

By locating the exact points at which the deterioration occurs, replacement and reparations of pipelines can be limited to only those sections in need of attention.

Deterioration is often confined to small localised sections that can total less than 2% of the entire pipeline.

Pipe corrosion does not occur uniformly across a network
