Pit Gauges Models

Pit Gauges assure compliance with corrosion allowances for equipment wherever corrosion affects materials, such as pipeline, vessels, piping, storage tanks, oil country tubular goods, drill pipe, bottom hole assemblies, bridges and structures, shipping, concrete, and aircraft components. Due to there versatility, many of our Pit Gauges have other uses, such as wear measurement, Weld Alignment, Structural Fit-up, etc. Western Instruments Dial Pit Gauges allow the Corrosion Inspector to conveniently measure Pit Depth or material loss in areas of Weight-Loss Corrosion.

We offer Various types of Pit Gauges for different applications, including the Tri-Gauge for basic evaluation and the Bridging Pit Gauge for evaluating large areas of weight loss corrosion, and much more.

For a complete list of features and accessories, please check all the Pit Gauges models below. If you are having difficulties finding the product you need, feel free to contact us and a product specialist will be happy to assist you finding a quality Shore Durometer that fits at a great price!

Prices: $450.00 to $570.00
Bridge Type Pit Gauges
The Bridging Pit Gauges is used to measure Dents and Buckles on Pipelines, Shell Settlement on Storage Tanks, etc. These various forms of Bridging Bars can utilize any of our exclusive Dial Indicators (Imperial, Metric, or Digital), with any of our Custom Engineered Contact Points. Western's advanced Bridging Pit Gauge System and our new Jr. Bridging Pit Gauge take over, where the capabilities of our standard Pit Gauges fall short, for evaluating large areas of Weight loss Corrosion. There are several important features to a Segmented Bridge, where various elements (Blades and Tees) are assembled to form a Bridging Bar. Firstly, they can be assembled to follow the contour of a slightly irregular surface. This contouring feature is important for Pipeline, Storage Tank, and Pressure Vessel inspections, where 'hills and valleys' always exist. Secondly, the models listed below are of a given length, however extra elements can be added to increase their over all length. As illustrated, these units can be assembled in Spanning or Cantilevering configurations, and finally, the Main Blade can be used individually for isolated or cone type Pitting.
