Hydro Testing
HydraTech offers pressure testing services for an extensive range of pressure from relatively few PSI to 30000 PSI. Hydro testing of pipes, pipelines and vessels is performed to expose defective materials that have missed prior detection, ensure that any remaining defects are insignificant enough to allow operation at design pressures, expose possible leaks and serve as a final validation of the integrity of the constructed system. high pressure oil and gas pipelines are tested for strength by pressurizing them to at least 125% of their maximum allowable operating pressure (MAOP) at any point along their length. ASME B31.3 requires this testing to ensure tightness and strength.
Mostly pressure testing is performed to below systems
Pipelines
Tanks & Vessels
Accumulators & Cylinders
Hydro test fluid is water always. Hydraulic pipelines, lube oil pipelines are tested with respective hydraulic oil / lube oil. Pressure gauges, temperature gauges, Pressure safety valves and Pressure & temperature recorder must have valid calibration for pressure testing works.
