Quest Integrity Group continues to innovate by introducing larger InVista™ tool sizes to meet industry demand for in-line inspection of unpiggable pipelines. The 16-inch tool is available now for ultrasonic in-line inspection projects and has completed a series of successful surveys in North America. This unique industry leading single module tool is followed by a 20-inch and a 24-inch tool that will be available for projects scheduled in Summer 2012.
The technology is a light weight tool that can be hand-carried, lifted and loaded. It performs in low flow/low pressure environments and can navigate 1.0D bends, including back-to-back and mitre bends. Along with this unique navigational capacity, the large diameter InVista tools boast longer battery life and faster on-board computing for greater axial flaw resolution and increased inspection velocity. The technology is ideal for space-constrained environments such as terminals, refineries and offshore environments and delivers a high-resolution data set for a detailed direct-measurement inspection with operational simplicity.
Like all of our intelligent pigging tools, the 16-inch tool uses ultrasonic technology to detect metal loss and deformations, is bi-directional and has dual-diameter capabilities. In addition to corrosion and dents, an InVista survey can also identify anomalies such as laminations and verify nominal pipe wall thickness. The survey comes with a complete engineering fitness-for-service assessment integrated with the standard pipeline feature table.
