Bridging Pit Gauge System

The Bridging Pit Gauge System allows the Corrosion Inspector to Span over or Cantilever into Large Areas of Weight Loss Corrosion, to obtain accurate and consistent measurements, or cross sections, of Pit Depth. As conditions dictate, the operator can simply use the Main Blade or can assemble the Bridging Pit Gauge up to an over all length of 28″ (725mm).

The contact Surfaces (Blades) of the Bridging Pit Gauge are fitted with an exclusive Knife Edge, so they can be used on Flat, ID (Convex), and OD (Concave) Surfaces, where a flat or notched contact surface can introduces error on Convex Surfaces. Like our Standard Pit Gauges, the Knife Edge gives the operator a clear view of the contact point, and the area being inspected.

With the addition of the optional Magnetic Hold Downs, the operator uses their width to quickly align the Bridging Pit Gauge System to a curved surface. This leaves his hands free to scan through very large areas of weight loss corrosion. This holds true when the Bridge Elements have been assembled with a slight contour on an irregular surface.

Jr. Bridging Pit Gauge Group

The Jr. Bridging Pit Gauge Group provides Inspectors with an Economical Alternative to the Bridging Pit Gauge System. The new Jr. Bridging Pit Gauge is available as 3 models; the standard Jr. Bridging Pit Gauge, the Plus, and the Super. The standard Jr. Bridging Pit Gauge assembles to an overall length of 13″ (340mm). The Jr. Bridging Pit Gauge Plus can be assembled in either Spanning or Cantilevering Configurations up to 15″ (394mm) long. While the Jr. Bridging Pit Gauge Super can also be assembled in both Spanning or Cantilevering Configurations, up to 27″ (685mm) long.

The Junior’s Main Blade, and the optional Extender Blades are fitted with strong magnets that secure any of the Jr. Bridging Pit Gauges to the surface of the workpiece. These Magnetic Hold Downs have several benefits, such as; Aligning the unit to Concave or Convex surfaces, keeping the operator free to record readings or manipulate the assembly when Scanning through Pits and Weight loss Corrosion. These features position the Plus, and the Super far ahead of any competitive units.

As Westerns Pit Gauge Product Series gains popularity, we are able to address various industry needs.  When Pipeline Inspectors see all of the different models of Pit Gauges we offer, and the boss wont shell out the money for one of our Bridge Type units, they figure out what they can get by with.  Due to customer requests, we now offer the Pipeline Inspectors Kit.

The Pipeline Inspectors Kit consists of the following components;

No matter which Blade the Dial indicator is installed on, all the components will fit inside the rugged Carrying Case.

The Basic Blade will most often have the Dial Indicator installed  on it, as the Basic Pit Gauge is by far the most popular Dial   Indicator Pit Depth Gauge we offer.  As illustrated to the right,  no matter the Configuration of assembly, everything still fits into  the rugged custom made carrying case.

Specified by a Senior Inspector, the Pocket Pit Gauge allows inspection on complex  curvatures, such as pump housings, impellers, turbine blades, etc.  As the name suggests, the Pocket Pit Gauge conveniently fits in your pocket (but then again so does the Basic Pit Gauge).

TriGauge: Western’s patented Lever Type Pit Gauge with Metric and Imperial Scales. Inquire at your supplier for information,

Assuring 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. Various types are available for different applications, including the Tri-Gauge for basic evaluation and the Bridging Pit Gauge for evaluating large areas of weight loss corrosion. The right gauge for the right application.
