Product Overview
Water and Wastewater
The efficient transmission of increasingly scarce water resources and the careful dispersal of wastewater are increasingly important environmental, economic and social issues. Public and private utility companies are investing continuously in new transmission infrastructure. They are also striving to maintain the quality of their existing pipeline stock.
Large diameter pre-stressed concrete cylinder pipelines (PCCP) are a significant investment for many water and wastewater agencies. Owners of these pipelines face a number of challenges relating to the management of their infrastructure. Assessing the condition of these pipes is an important task.
Some water utilities have limited access to their buried pipes. Other agencies have little redundancy built into the system, requiring owners to conserve water as much as possible and keep pipelines in service. Corrosion-induced failure in the wire wrapping of PCCP can result in ruptures with consequent interruption in service, potential flood damage and public safety concerns.
P-Wave® is a patented electromagnetic inspection technology for evaluating the current condition of pre-stressed concrete cylinder pipelines. P-Wave locates and quantifies the extent of wire breaks in pipes. The technology assists assets managers to prioritise their pipeline repair, replacement and monitoring programmes.
SoundPrint® acoustic monitoring detects and locates pre-stressing wire failures as they occur. It offers the only non-intrusive way to evaluate pre-stressed concrete cylinder pipes without the need for de-watering. SoundPrint can also be used to remotely monitor wire strand failures in pre and post-tensioned concrete water reservoir walls, and is patented in many countries.
SmartBall® is a new and innovative leak detection technology. It is comprised of a foam ball containing a range of acoustic and other sensors which travels with the water flow down a pipe, detecting locating leaks as it rolls. The SmartBall emits pulses that enable its progress to be tracked and retrieved. It is applicable for all types of pipe including concrete, steel, ductile iron, PVC and GRP, and is patent pending.
Pipeline Risk Management System (PRMS) Pure Technologies’ suite of products equip water and waste water operators with baseline and deterioration rate information which enables them to implement cost-effective and proactive risk management systems and timely and targeted rehabilitation or replacement programs. These can have important economic impacts including:
- Significant cost savings while maintaining the value of critical assets
- Simplified tracking of extensive pipeline networks
- Comprehensive dynamic risk and asset management capability for pipeline owners
Oil and Gas
The oil and gas industry places great importance on the need to minimize the environmental, economic and social costs of accidental hydrocarbon escapes from its pipelines. Leaks of oil can result in soil and groundwater contamination, or cause fires and explosions. Leaks from Natural Gas pipelines also present fire and explosion risks as well as loss of profits.
Pure Technologies has innovative solutions for monitoring the integrity of hydrocarbon pipelines.
SoundPrint® AFO leak and intrusion detection systems provide complete protection for oil and gas transmission pipelines. Using proprietary continuous fiber-optic acoustic sensing technology, pipeline operators can detect and locate small leaks before they cause environmental damage. The detection threshold is far more sensitive than conventional instrumentation-based or modeling systems. The system can also detect interference with pipelines caused by construction operations or malicious activity so that damage or product theft can be prevented.
SmartBall® is a new and innovative leak detection technology from Pure Technologies. It is a free-swimming ball with an instrument-filled aluminum alloy core capable of detecting and locating very small leaks in pipelines.
SmartBall® can be inserted and retrieved from a pipeline under normal operation. The ball travels with the product flow for up to 170 hours, collecting information about leaks over many miles of pipeline with a single deployment. Pipeline sizes of 4 inches (100mm) and greater can be inspected.
Bridges
Bridges are some of the most critical, valuable and highly visible components of the world’s transportation infrastructure. Proactive monitoring, management and surveillance of these structures is of the utmost importance to their owners and managers.
SoundPrint® offers bridge owners and engineers a tool that helps ensure the long-term integrity of post-tensioned, pre-tensioned, suspension and cable-stayed bridges. SoundPrint® detects and locates tensioned wire failures through continuous, non-intrusive remote monitoring. SoundPrint®:
- Collects acoustic information from widely distributed sensors;
- Determines the time, location and frequency of wire failures;
- Monitors entire structures and pinpoints localized problem areas;
- Helps develop accurate maintenance budgets.
Corrosion of bridge cables or ropes is not always evident from visual inspection, as corrosion often originates in the interior of cables. CableScan™ is a new cable inspection service that utilizes magnetostrictive sensing (MsS) to identify anomalies in bridge cables from a single location on each cable. Pure Technologies holds a worldwide non-exclusive license for MsS for bridge applications. The system represents a major breakthrough in bridge inspection technology. CableScan devices:
- generate and detect guided waves electromagnetically in ferromagnetic materials;
- identify the condition of cables and the location of any defects;
- provide a preliminary report so that cables can be selected for close-up visual inspection, removal, load testing and/or forensic analysis.
Buildings and Parking Structures
The tendon systems of post-tensioned concrete building structures such as many multi-storey commercial buildings and car-parks are vulnerable to moisture ingress. Such ingress, which can occur at any time, can cause corrosion-induced failures in these structures. Current non-destructive evaluation techniques are ineffective for evaluating the condition of post-tensioned systems. Furthermore, intrusive inspection techniques whilst useful in the initial assessment of a structure can only provide a sampling of the condition of the wire strands that form the tendons.
SoundPrint® continuously monitors every wire strand in a building and will identify the time and location of their failures. Since SoundPrint can also determine the frequency of wire failures, statistical techniques can be used to estimate future rates of failure in different parts of a building.
Through the Pure Technologie's web site, clients can access data from their structures directly. Using the intuitive interface, managers can custom-design their own reports, which are generated in real time. This product provides building managers with desktop access to a reliable, single-source of information on their assets where it’s needed, when it’s needed.
