The Bridging Pit Gauge System is the most advanced Bridging Bar (Pit Gauge) of its type in the world. Originally developed for Pressure Vessels, it was quickly adopted for use to Pipelines with the introduction of US DOT PHMSA 49 CFR Part 192. This adoption happened due to Western’s introduction of Magnetic Hold Downs. The Bridging Pit Gauge was originally designed to assess large areas of Weight-Loss Corrosion, however, with the introduction of our Magnetic Hold Downs it was quickly accepted, as the best tool of its type, for Pipeline Corrosion Assessments.

All of Western’s Bridge Type Pit Gauges are Segmented, where the different parts (Blades & Tees) are assembled to form a Bridging Bar. The Bridging Pit Gauge’s components can be assembled in different configurations, such as Spanning or Cantilevering In the Cantilevering configuration, operators can deal with Welds (Circular, Long Seam or Spiral) or next to Reinforcing Pads or Risers.

The Bridge can be assembled to follow the contour of a slightly irregular surface (or rigidly if needed). Extra Tees and Connector Blades can be added, to extend the length of the Bridge. Virtually all of Western’s Pit Gauges have a knife edge, so they can be easily used on either flat, concave (ID), or convex (OD) surfaces. Like all of the Pit Gauges, all three models of our Dial Indicators can be fitted to a Bridging Pit Gauge.
