LiquidPower Specialty Products Inc. (LSPI), a Berkshire Hathaway Company, is the global leader in the science and application of drag reduction. LSPI specializes in DRA technology by maximizing the flow potential of pipelines, increasing operational flexibility and throughput capacity, and substantially increasing bottom-line profit.LSPI developed its pioneering technology in the 1970s, using flow improvers (also known as drag reducing agents, or DRA) to lower frictional energy loss by reducing turbulence in the pipeline. This technology allows pipeline operators to increase throughput and reduce energy costs while limiting capital investment.
