APT PNEUMATIC PRESSURE TESTING
Earlier evidence. Better temperature compensation.
APT combines acoustic temperature measurement with pressure data and PE creep compensation to support technically informed testing of large-volume pipelines.
ACOUSTIC TEMPERATURE MEASUREMENT
APT helps separate temperature effects from the pressure-test evidence
Even a small change in the average temperature of the air inside a pipeline can produce a noticeable pressure change. APT measures that temperature movement acoustically so it can be considered alongside pressure and PE creep
PRESSURE DOES NOT MOVE FOR ONE REASON ALONE
Temperature, creep and leakage can all influence pressure
APT brings these effects into one test record so the corrected pressure behaviour can be compared with the predicted creep and allowable-leak curve.
What this changes
The test team can distinguish temperature-related pressure movement sooner and focus investigation where the corrected trend remains above the predicted curve.
