Description

EFC Inflatable Rings

Inflatable transducer rings are designed to provide effective inspection capability for larger diameter pipes. Pneumatic pressure is used to press the transducers modules that are mounted onto this ring against the pipe wall. These modules are fully interchangeable between inflatable collars of all sizes.

For diameter above 36″, two smaller inflatable type rings can be linked together as detailed in a specific procedure for joining rings. Non‑standard sizes and larger sizes up to 60″ can be produced to special order.
