Zetec’s New High Stability Bobbin Probe Can Deliver Increase of 30% or More in Probe LifeZetec86, Snoqualmie, WA, USA
Snoqualmie, WA — Zetec, Inc. introduces the new High Stability Bobbin Probe for steam generator tubing inspections. This innovative advancement in technology provides better quality data and probes that last considerably longer.
The High Stability Bobbin Probe introduces innovative features that deliver significant benefits. A new centering foot design features spring supported centering feet and proprietary abrasion resistant material enabling the probe to center more accurately for a longer period of time. The improved data cable provides less data drift than other available options, increasing the probability of flaw detection. The cable was carefully designed to allow the probe to meet the EPRI equivalency for the peak center frequency so it’s inspection ready. Equivalency reports can be provided to allow the probe to immediately be used as an inspection of record.
Field trials conducted at Palisades and Diablo Canyon confirmed improved data quality and average probe life increases exceeding 30%. The longer probe life leads to numerous improvements in inspection economics. Not only is the time for an inspection significantly reduced, but savings are also realized for less rad waste and lower dose because of the fewer probe changes.
“As the largest supplier of probes worldwide to the steam generator market, we understand the challenges our customers face and develop solutions that deliver the results they need. This new High Stability Bobbin Probe is a perfect example of that. With a longer probe life, customers can save tens of thousands of dollars on inspections” states Bill Ziegenhagen, Zetec Probe Product Manager.
The High Stability Bobbin Probes are designed to be equivalent for replacing the existing bobbin probes already used in nuclear steam generators. Sizes for 7/8, 3/4, 11/16 and 5/8 tubing are available. For more information on the High Stability bobbin Probe, please visit www.zetec.com.
