![]() ![]() ![]() Mechanical arms measure the distance from the center of the pipe to the inside of the external wall assessing ovality, dents, pipe buckling, bulges, and pipe expansion. *Small Diameter Multiple Body Caliper Inline Inspection Tool Tool Components: Mechanical Arms: Caliper Inline Inspection Tool Diagram with Components Caliper pigging is the most accurate and cost-effective method to evaluate a pipelines current position and geometric condition. Several factors can cause a pipeline to shift from natural factors such as land slide to made factors like ship anchors. ![]() Location Based 3D Mapping:Ĭaliper pigging also allows for highly accurate 3D location-based mapping. Deformations can also lead to the increased possibility of catastrophic pipeline failure leading to damage to the environment, surrounding community and financial losses. Caliper pigging is crucial to ensuring pipeline efficiency and maximum transfer of materials. Tool performance and reporting to POF 2016 specificationsĭexon Caliper Pigging Services: Pipeline Geometry and Deformation Analysis:ĭeformations and deposit build ups can result in material flow rate losses and pressure variations.Tri axial inertial measurement units for XYZ mapping capabilities.Tool diameters range from 4” – 52” (with customized tool development services also available).Dent, bulge, pipe expansion and buckling measurements.Suitable for pipelines of any length and material.Pipeline feature detection includes but is not limited to the following pipeline features Anomaly Detection:Īnomalies that cause changes in internal diameter (I.D.) include but are not limited to Caliper PIG’s are regularly used in conjunction with other forms of intelligent pigging such as Ultrasonic and Magnetic Flux Leakage (MFL) inline inspection. This information is critical during the pre-inspection qualification process in preparation for inline inspection runs. Caliper Pipeline Integrity Gauges (PIGs) use mechanical arms to accurately record the geometric conditions of a pipeline as well as pipeline features by measuring changes in a pipeline’s internal diameter (I.D.). ![]()
