Gauging pigs


Gauging pigs of SKK type

Gauging pigs are designed to estimate the minimal nominal bore values for pipelines that need to be determined in the following cases: for a new pipeline after the construction-assemblage works are completed; for pipelines that have been under repairs; for pipelines that have not been tested with an in-pipe flaw-detector before. Based on the results of running the gauging pig decisions are made on whether further running of cleaning devices and flaw-detectors through the pipeline is required. Details
