PIPELINE PIGGING TECHNOLOGY- P3

PIPELINE PIGGING TECHNOLOGY- P3: Why pig a pipeline? This paper introduces a number of reasons for doing so, together with a discussion of the advantages and alternatives. In general terms, however, pigging is not an operation to be undertaken lightly. There are often technical problems to be resolved and the operation requires careful control and co-ordination. | Pipeline Pigging Technology U.S. FEDERAL PIPELINE SAFETY REGULATIONS METHOD J. 2.
