Vivax-Metrotech vLoc3-DM Pipeline Current Defect Mapper

The vLoc3-DM from Vivax-Metrotech is the new industry bench mark for Pipeline Defect Current Mapping instruments (PCM/PCDM). The vLoc3-DM is built on a new Triaxial 3D architecture that offers best-in-class performance and innovative features that are unique to the vLoc3-DM. It's class leading 4.3" color LCD high visibility display provides a locating refinement that is heads above its competition. The display screen has been uniquely configured specifically for the pipeline evaluation professional. Data can be graphed in "real-time" on the receiver, while on the site. The "walk-back" feature highlights the users position on the graph allowing the exact location of any point-of-interests where further examination or an ACVG, A-frame survey can be undertaken.

The vLoc3-DM Pipe Defect Current Mapper is a professional pipeline multi-tool designed to identify pipeline coating defects and contact shorts to other structures that can render cathodic protection ineffective and also as a standard EM pipe locating system. Using with the attached magnetometer (foot) users can identify areas of the pipeline where coating defects are present. When used with the A-Frame (ACVG) users can pinpoint defects for excavation and restoring.

There are hidden images / Tidy mode active.

Pipeline Integrity

Pipeline professionals have millions of miles of pipe networks to protect and manage in real-time. Instruments like the new vLoc3-DM from Vivax-Metrotech serve an important and vital role with helping corrosion technicians and engineers confirm integrity of the pipeline and helping to secure the safe transportation of the nation's natural resources.

The vLoc3-DM (Pipe Defect Mapper) is a multi-tool that provide a proven method of detection and targeting of pipe coating defects and ¹holidays along troubled areas on the buried pipeline. This is done by using its 150-watt special transmitter and its specially equipped receiver while simply walking the path of the pipeline. The vLoc3-DM also detects when a ²short occurs from an adjacent metallic utility onto the pipeline, causing the cathodic protection (CP) to become ineffective.

Using the A-frame the vLoc3-DM becomes an ³ACVG tool and allows users to then mark the exact location of these coating defects for repair personnel.

¹HOLIDAY - A holiday is defined as an area of the pipe where the coating thickness is insufficient, a pinhole within the coating, a crack within the coating, an improper adhesive or bonding of the coating. When a holiday is detected, urgent corrective action must be taken to ensure the safety of the pipeline.

²SHORT - Is when contact with other metallic structures causes the cathodic protection (CP) / DC current to use the foreign utility as a path off the pipe.

³ACVG - Alternating Current Voltage Gradient provide a faster and more convenient system for pipeline integrity surveys and is also a method to detect and marks exact locations of coating defects.
