The original inflatable ring designed for general pipe inspection.

HD-Ring-web

Description:

The Enhanced Focusing Capability (EFC) ring are designed to provide effective inspection capability, particularly for large diameter pipes. Pneumatic pressure is used to press transducer modules (which are mounted onto this ring) against the pipe wall. These modules are fully interchangeable between inflatable collars of all sizes.

For sizes greater than 24 inch diameter, two smaller inflatable type rings can be linked together as detailed in a specific procedure for joining rings. Non-standard size (up to 60 inch) and 8 channel (non-EFC) rings can be produced to special order.
