The X2 Spider is a third generation remote scanner capable of ultrasonic corrosion inspection for tanks, pipes and vessels. The parts are machined from billet 6061 Aluminium and 303 stainless steel with strategic cavities for weight reduction.


This combination provides a durable yet agile crawler.  The X2 is a highly maneuverable system and is capable of traversing difficult obstructions made possible by the high suspension compliance.  It is designed with a proprietary direct drive gear set and does not use any belts, chains, set screws, or clamps, which eliminates slippage.

The  unit is completely sealed from the environment and has a hard coat anodized exterior to reduce environmental wear on the system.  The scanner utilizes rare earth motors with the highest power density available to provide a high-performing crawler.  Single and dual element transducers are included in the system to adjust for variable conditions.  Each scanner is manufactured in-house and is rigorously tested, so ensuring the scanner is of the highest quality.
