Water pipe inspections system

Our clients believe that PPIC's RFTC technology provides them with the best possible evaluation of their water supply infrastructure. This confidence is demonstrated by:

PPIC's commercial RFTC inspection service is based on over 15 years of intensive Research & Development. We are the acknowledged global leader in the evaluation of water pipelines. To date PPIC has:

Water supply system managers want to maintain reasonable costs, while ensuring and extending the safe economic life of the lines.PPIC's RFTC inspections give them the information they need to both assess the condition of their critical infrastructure, and develop a methodology that effectively manages the inherent risks.

In addition to determining the location and number of wire breaks anywhere along the length of a pipe, a RFTC inspection enables our clients to construct an informed cost/benefit analysis. For a small percentage of the cost of the asset, water supply system operators can potentially avoid the enormous expense of complete pipeline replacement by simply identifying the specific pipes that have a risk of failure. Operators can also use the analysis provided by a PPIC inspection to:

The application of this knowledge is critical to PPIC's ability to accurately interpret the "noise". As PPICs RFTC inspection system is sensitive to all the electromagnetic properties of PCP, it is capable of detecting not only wire breaks, but it can also detect holes or perforation of the steel cylinder if they are of a sufficient size. The system also detects the features of a pipeline including manholes, blow-offs, and joints.

PPIC's Remote Field Transformer Coupling technology functions much in the same way as a radio transmitter and receiver. The "transmitter" produces an electromagnetic field. The prestressing wires in the pipe amplify the signal. If there are broken pre-stressing wires, the signal does not come through cleanly and our "receiver" picks up static, or noise.

PPIC's trained field crews record this noise as they travel through the pipeline. In the Analysis phase, PPIC's skilled analysts quantify this noise and estimate the number of wire breaks per pipe by applying knowledge accumulated from the following sources:
