Pure Technologies, the parent company of PureHM, developed the original PWA system to identify…


Is batch tracking a viable solution to track ILI tools?

Canada has approximately 100,000 kilometers (62,000 miles) of transmission pipeline ranging from 4 to 48 inches in diameter. With the large distance of pipeline and the expectation that Global energy demand will increase by 33% by 2035, safe pipeline operations will continue to be at the forefront for operators. To reduce costs associated with inline inspection (ILI) programs, pipeline owners…
