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!

The Bridging Pit Gauge can be assemble up to a length of 28.5" (724 mm) long; can be extended if necessary
Available with dial or digital indicators
The Western Instruments N88-11 Jr. Bridging Pit Gauge 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.

Western Instruments N88L-3 Multi-Weld Gauge

3 separate scales
7 unique diameter comparators
The Multi-Weld Gauge is a precision instrument that provides an easy to read measurements of the following welding and fit-up parameters; Internal Hi-Lo, Gap, Filet Height and Leg Length, Weld Height, Undercut Depth, Misalignment, and Angle of Preparation. The Multi-Weld Gauge is equipped with 3 separate scales for all measurements. Metric and Imperial (Thousands of an inch and fractions of an inch). Rules for liner measurements are located on the top and bottom of the Front side of the Scale Plate. The Multi-Weld Gauge is also equipped with 7 unique diameter comparators which are half circles in 1/16" to 1/2" in 1/16" increments (1.6mm to 12.7mm in 1.6mm increments) for convenient diameter estimates (Filet Welds, Welding Rod/Wire, etc.)The Multi-Weld Gauge does away with Single Purpose Welding Gauges, by consolidating the functions of the 4 most popular gauges, with over 9 measurement functions. The contrast of the scales against the black background, make the Multi-Weld Gauge extremely easy to read on any of its measurement scales. The Multi-Weld is unique, a distinct improvement over existing gauges.Weld and Fit-Up parameters are outlined in numerous industry specifications, such as; AWS, ASME, API, ANSI, ISO, DIN, CEN, and Military Specifications. Of particular importance for AWS Inspectors, the Multi-Weld Gauge will resolve and measure Undercut to +/- 0.010 (0.5mm), something no other Lever Type Welding Gauge can do.
