The gauging-disc is a circular aluminum plate of a certain specification, and the outer edge is generally divided into 12 equal parts, which are hung on the pig to run in the pipeline to measure the maximum deformation in the pipeline.
Gauging disc can check whether the pipeline is deformed. The material is aluminum (soft, better to pass through the deformed pipeline without jamming). Generally, the diameter is 80% – 95% of the inner diameter of the pipeline. If there are no specific requirements, it is usually 85%. The caliper plate is generally placed in the middle of the pig.
Definition
The gauging disc is a circular aluminum plate of a certain specification. It is hung on the pig to run in the pipeline to measure the maximum deformation in the pipeline and the minimum elbow and other factors restricting the passage of the detector. Different specifications of the diameter of the pipe using different specifications of the measuring plate, according to the pipe diameter of 90%, 85%, 80%, and other proportions vary. The thickness of the diameter plate is also different, there are 3mm,5mm,6mm, and so on.
