Cleaning module for a pipeline inspection gauge

A cleaning module for a pipeline inspection gauge configured for insertion into a pipeline, the cleaning module comprising:

• a body portion;
• a suspension assembly coupled to the body portion;
• at least one brush coupled to the suspension assembly, the suspension assembly configured to bias the at least one brush radially outward and into engagement with an arc defined along an inner surface of the pipeline when the pipeline inspection gauge is in the pipeline, wherein the cleaning module is configured to clean the pipeline along the arc without cleaning portions of the pipeline circumferentially adjacent to the arc;
• and
• an anti-rotation device coupled to the body portion and configured to reduce rotation of the cleaning module within the pipeline.

A method of inspecting a pipeline, the method comprising:

• inserting a cleaning module into a pipeline;
• moving the cleaning module a distance through the pipeline in order to create a cleaned arc line along an inner surface of the pipeline that extends the distance, wherein rotation of the cleaning module is limited when the cleaning module is moved the distance through the pipeline;
• engaging a sensor module with the inner surface on the cleaned arc line;
• and
• taking electrical measurements along the cleaned arc line.
