Abstract
Systems and methods for cleaning an internal bore of a tubular member with a pipeline pig include a pipeline pig having a pig body with a fore end and an aft end opposite the fore end. A cup circumscribes the pig body, where an outer diameter lip of the cup engages a surface of the internal bore of the tubular member. A scraper assembly includes a scraper arm extending radially outward from the pig body and a spring biasing the scraper arm in a radially outward direction. A load cell is positioned to measure a movement of the scraper arm in a radially inward direction. A treatment trigger is actuated by a treatment signal from the load cell to deliver a treatment system to the internal bore of the tubular member, where the treatment signal is generated by the movement of the scraper arm in the radially inward direction.
