- These transducer rings are designed to provide effective inspection capability, particularly for larger 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. Both standard modules and adjustable modules (that allow low-frequency operation) are available.
- 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 sizes (up to 60 inches) and 8 channel (non‑EFC configuration) rings can be produced to special order.
