Abstract
A method for cleaning a pipline by providing a filter or a number of filters adapted to reside in the pig launcher of the pipeline. The filters can be used to remove debris and impurities from the fluid flowing in the pipeline during a pigging operation. Alternatively, the filters may be retained in the pig launcher for extended periods of time.
