Pipeline Restart Loop: Yield Stress
|
The new Pipeline Restart Loop is suitable to perform a variety of pipeline restart tests: |
Pipeline blocking simulation with exchangeable test pipelines
- Yield stress tests (yield strength measurements)
- Flow improver / deposition inhibitor testing
The exchangeable test pipeline is filled with the sample and cooled down to a set temperature.
The cooling rate is programmable (temperature profiles).
|
After cooling, the pump starts to press the sample through the pipeline at very low flow rates. The increasing pressure is measured at high sample rates. The pressure/time curve shows the yield break at its maximum. Measurements with untreated samples can be compared to measurements with treated samples to show the chemical's effectiveness. |
|
The especially designed high-accurate pump system provides an absolutely pulsation-free flow, with maximum pressure starting at zero flow rate. So, very realistic shear and flow regimes inside the test pipeline are possible.
The exchangeable test pipelines can have a length up to 20 m at OD 1/4", even onger at smaller diameters.
