Sahara PURE
Tethered tool for pipelines inspection
The Sahara platform is a tethered inspection tool for assessing pressurized water pipelines DN150 and larger. The platform detects leaks and air pockets, collects visual condition, and maps pipelines in a single deployment, without disrupting regular service. With this condition assessment data, pipeline owners can make informed rehabilitation and management decisions on a pipe-by-pipe basis.
Brief characteristics
TechnologyAcoustic
The range of pipeline diameters for applicationDN150 ÷ DN2000
Accuracy and sensitivityLeaks from 0.2 l/h with location accuracy up to 0.5 m
Compatibility with pipeline materialsAll pipeline materials, including:
steel, cast iron, reinforced concrete, PP, PE, PVC, PVT, fiberglass, asbestos cement
Length for one inspectionup to 1.5 km
Features
Locates very small leaks and air pockets in real time with high accuracy. Ideal for complex pipeline networks requiring precision control and location accuracy. Easy-to-deploy through existing pipeline features 2 inches (50 mm) and larger. Can be deployed in no-flow conditions. Real-time pipeline mapping confirms the alignment and locates pipeline features. Captures live video of the pipeline interior.
The main goals achieved during the inspection:
- detection of leaks;
- detection of gas pockets;
- video recording/broadcasting of the state of the pipeline;
- GIS cartography;
- definition of connections to the pipeline (authorized and not).
During the inspection, PURE Technologies specialists in real time:
- detect 98% of all leaks (last 2% after inspection, within 4 weeks of analysis), gas pockets, authorized and unauthorized connections to the pipeline;
- carry out on-line video surveillance / fixing the state of the internal walls of the pipeline;
- determine the location of anomalies;
- create a GIS map of the pipeline.
The results of the inspection are:
- a detailed report on leaks (100%) and anomalies found during the inspection;
- GIS map with the plotted pipeline and coordinates of the detected anomalies;
- video inspection recording;
- Top-priority recommendations from leading experts of PURE Technologies.
