Drag Reducer Agent TurboFlow is a special polymer that injected into a pipeline transporting fluids (crude, refined products, non-potable water) so reducing the frictional losses in the pipeline. The concentration injected is very small (in fact, in PPM levels) Drag reducer research started in early 1970's. Flow is turbulent in most pipelines.

The word "cryogenic" means "producing, or related to, low temperatures," and all cryogenic liquids are extremely cold. Cryogenic liquids have boiling points below -150°C. The vapours and gases released from cryogenic liquids also remain very cold. They often condense the moisture in air, creating a highly visible fog.
