Vessel Inspection Kit – N88-VI

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.

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.
