iGrab™ Vacuum Articulating Guide Tube

Challenge Foreign object debris (FOD) removal is a critical procedure in any complex mechanical assembly. FOD creates unwanted vibrations and/or damage to these assemblies, especially those used in the aerospace and/or power generation industries. A nuclear power generation inspection and cleaning division needed to remove magnetite (metal flake debris) FOD from a large containment vessel that was difficult to access. The access port was a perpendicular, 2-inch diameter hole into a 22-inch diameter pipe. The FOD existed throughout a 60-foot section of the said pipe.  Development Due to the abundance of the magnetite FOD in the pipe, InterTest sales and engineering teams developed a retrieval tool with powerful vacuum suction and 4-way articulation. With no on-site consultation, the InterTest concept based its measurements and specifications on the application information shared by the customer. The environment where the retrieval tool would operate was abrasive, so the tool was made
