Pipeline Pig Gauging Plates

Aluminum gauging plates are used in conjunction with steel pig bodies.  They prove pipe roundness and ensure excessive weld penetration or debris does not exist in the line. When attached to a pig, aluminum gauging plates can provide the minimum bend radius prior to intelligent pig runs.

Gauging plate OD’s range anywhere from 90 to 95% of the internal diameter of the pipe and can also have slots cut unto the circumferential perimter for easier deformation identification . The standard construction material for gauging plates is 1/4 ” thick aluminum , but mild steel can be used.
