Using EST Group's patented tooling, our service technicians can isolate and hydrostatically test plain open end pipe, welded flange-to-pipe, and flange-to-nozzle in minutes. Each testing plug is designed to minimize the amount of water consumed during testing. This not only speeds filling and draining operations, but reduces water handling and treatment expenses. All hydro testing application tests are carried out to ANSI B16.5 requirements.
