Caliper Geometry Inspection Tool

Caliper geometry inline inspection tool Unlike conventional caliper survey equipment, the Enduro Digitel Data Logger (the DdL) offers both radius point readings and diametrical cross-sectional analysis; multiple channels are provided offering the ability to log pipeline anomalies in clock orientation. Gyro inputs provide the ability to determine bend radii and bend direction (up from down – left from right); the angle of the bend is also determined.

Global Positioning System (GPS) equipment works well with the DdL. Excavations may be determined from logged GPS readings and given in GPS excavation points. With the reference points established, calculations are then made to determine the GPS coordinates and station at the anomaly location to be excavated.

The Above Ground Marker (AGM) is available for all DdL surveys. Enduro's traditional AGM equipment provides a reference location at specific points along the pipeline. These locations are logged directly to the DdL recorded data. The signal and location is then stored in the DdL for future reference and location assistance.

With the use of twin gyros on the DdL, profiling and mapping of the pipeline is possible, as direction and angle readings are made on all bends. Bends are easily seen and may be used as reference locations when locating anomalies. Enduro's DdL equipment is capable of traversing and recording bend radii of normal radius of 1 and a half times pipe diameter; bends of 1 diameter have been logged with special tool adaptation.

The DdL survey tool is available in sizes 4 inch through 60 inch; all having multiple channels of geometric data and all anomalies logged in clock orientation.
