Title: David E. Russell: Innovator in Pipeline and Boiler Inspection Technologies
Introduction
David E. Russell is a notable inventor based in Edmonton, Canada. He has made significant contributions to the fields of pipeline inspection and boiler tube defect detection. With a total of 4 patents to his name, Russell's work has advanced the technology used in these critical areas.
Latest Patents
One of his latest patents is a "System and method for retrieving in-line leak detection devices." This innovative system is designed to retrieve a buoyant leak detector traveling with the fluid flowing in a pipeline. It includes a catchment device located above the bottom interior of the pipeline. Flexible, elongate manifold structures are constructed with fluid outlet openings extending along the manifold structures. These structures are deployable to lie across the lower inside perimeter of the pipeline, upstream from the catchment device. A source of pressurized air is routed to the manifold structure, allowing air bubbles to be emitted from the nozzles. This creates a sheet or curtain of air bubbles that directs the leak detector toward the catchment device.
Another significant patent is the "Apparatus and method of detecting defects in boiler tubes." This invention features a probe that includes exciter units and detector units arranged in arrays. These arrays are positioned to match the exterior circumference of an individual boiler tube. The detector units are 'absolute' coil detectors used to detect and quantify general wall loss, such as that caused by steam impingement erosion. The probe can be moved along the boiler tubes by hand, allowing for thorough inspection.
