9800 Series Ovality Gauges

These unique gauges are made in a complete range of sizes from 2-3/8” thru 20” diameter. They consist of a rugged frame, a spring loaded measuring contact as well as 4 contact rollers. This 5 point contact with the pipe surface to assures stability and centerline measurement. Variations of pipe diameter, such as Ovality, improper size as well as triangular distortion are easily determined. The frame resists heat conduction, so measurements can also be taken on hot pipe. For ease of use and stability, a different gauge is required for each pipe OD. Standard sizes and some special sizes are available, see chart below.
