Abstract: Frietion reducer is a means by which to whip up the throughput of a pipeline。Plenty of cases at home and abroad are cited to show the success in applying it。At set pipe diameter, application of friction reducer is a method flcxibel, economical and fast to make a pipeline throughput adapt to demand for increasing throughput。It alos explains the feasibilty of using it in our country for such purpose。With the continuous development of friction reducer at home, it will surely be playing an important role in this direction。
