The Application of Small-scale Centrifugal Pump in Hydrostatic Testing of Small or Medium Diameter Pipe in the Horizontal Direction Drilling Project

During the horizontal direction drilling project of pipeline, two hydrostatic tests, the strength test and leak test for the pipe before it pullback, and leak test after it pullback, have to carry out. Generally, the small-scale centrifugal pump, the necessary equipment, will be used in the hydrostatic test. This article introduces the application method of centrifugal pump in hydrostatic test.
