Drag Reducing Agents
Drag Reducing Agents (DRAs) or Flow Improvers are materials that reduces frictional pressure during fluid flow in a conduit or pipeline. Using DRAs allows increased flow using the same amount of energy or decreased pressure drop for the same flow rate of fluid in pipelines. PETROFANN DRAs consist of long-chain hydrocarbon polymers that act as buffers along the pipe wall to decrease the amount of energy lost in turbulent formation.
