Friction Flow Loop for Drag-Reducing Agent Tests

Manufacturer: Vinci Technologies
Model Number: DRA Flow Loop

The DRA flow loop enables the end user to test, quantify and evaluate the performance of a friction reducer by measuring frictional pressure loss of a fluid flowing in a pipe in turbulent flow. The effect of friction reducers on both flow rate and pressure are analyzed and reported. The apparatus provides fast, accurate and reliable results for research of friction reducers. The system circulates test fluid through two test sections of various diameters to generate differential pressure versus flow rate data. The test fluid injection system comprises a mixing tank to fully mix additives into the test fluid and a low-shear pump for injection of test fluids with the flow rate controlled by a Coriolis flow meter. High-accuracy differential pressure transducers are provided for each tubing diameter for multiple data readings per test. Additives can be injected into the flow stream via a metering pump or added directly into the mixing tank. Differential pressure, pressure, temperature, flow rate and Reynolds number are computed in real time. The system can be operated in open and closed modes. It is easy to set up, operate, clean, maintain and calibrate. It also offers flush-and-fill automation for easy system clean up.
