Guidetubes for wide range of turbine inspections

Guidetubes are a great accessory for your 4mm borescopes. The combination of borescopes and guidetubes allow you to inspect turbines without taking apart said turbine. They’re essential for directing borescopes into specific areas during the inspection process, and with the use of articulating borescopes, they’re perfect for snaking through tight spaces and around corners. Most borescope guide tubes are made of metal and remain rigid throughout the inspection process.

A borescope allows for assessment of hot section components for wear or damage that may not be evident from a regular ground power check or flight data collection. For instance, for turbine engine inspection, inserting a borescope through the exhaust duct port and power turbine stage may reveal trailing edge cracks on compressor turbine blades. Portable Videoscopes have made this borescope inspection procedure much easier to facilitate.
