Using drag reducer to raise pipeline energy saving efficciency

The important aspect in pumping station's energy saving is to reduce pipeline resistance so as to raise pipeline efficiency. There are two ways for raising pipeline efficiency: adding drag reducer and improving fluid moving boundary condittion. The arlicle gives major introduction to the propertise, charaiteristics and application of a newly developed drag reducer, analyzes basic factors affacting its properties and its main advantages, and discusses the relationship between pipeline energy saving and pumping station energy saving.
