Prior to pipeline pre-commissioning, utilize special Caliper to verify the geometry deformation of constructed pipeline by executing inspection work with air compressor as power supply. It can establish detailed pipeline information; timely find the pipeline geometric problems after the pipeline construction. It is one of the most important digital basis for Pipeline Integrity Assessment, and the supplement or substitute of traditional aluminum Caliper pigging.
The deformation sensor is hidden under the cup, which can effectively reduce the impact of high speed and high vibration on the sensor. High speed data acquisition system is adopted for the deformation inspection of newly-built pipeline.
