Unsteady fluid flow in small diameter pipeline at the chemical reagent delivery into the well

The problems of irregularity of chemical reagent delivery by the small diameter pipeline at plunger metering pump ope ration, the way to reduce fluctuations due to the connection of an insert, made of fiber reinforced polymer pipeline, are considered. The recommendations on the use of fiber reinforced polymer pipeline in capillary systems of chemical reagents delivery into the well are given.
