Tube Sheet Pit Gauge

The Tube Sheet Pit Gauge® is designed to fit inside most ½” OD (0.500” or 12.7mm)  Boiler Tube, where the resulting Inside Diameter is just over ⅜” (0.375” or 9.5mm).  Without having stated the obvious, the Tube Sheet Pit Gauge will also test larger ID  tube where reaching into the Tube is necessary.

The overall length of the Tube Sheet Pit Gauge® is 23 ½” (600mm), with a working length of 12 ½” (320mm) on the minimum diameter and 20” (500mm) on 1 ½” ID (38mm) Tube.  However, ‘Specials’ can be ordered to reach into tubes much farther, within practical limits which we consider to be 6’ (1.8m).

The Axially Mounted Indicator is able to rotate through 360°, thus the Barrel of the Pit Gauge can rotated to any radial position.  This allows the operator to reach into the tube ID, to measure Pits, allowing the operator to have a clear view the Dial face. The Contact surface, from where the Contact Point extends, is simply aligned by the operator, against the target point.  A reference surface (flat) is positioned on the Dial Indicator Mount, to provide the operator with a visual and physical reference for his radial position. The Tube Sheet Pit Gauge® has a maximum measurement range of up to  0.150” (3.8mm), and resolves to 0.001” or 0.01mm.
