APT PNEUMATIC PRESSURE TESTING

APT Pneumatic Pressure Testing for Pipelines

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.

Pipeline information required to plan an APT pressure test

PROJECT INFORMATION

A suitable test starts with the right inputs

Send the basic installation and programme information first. MTS will review the arrangement, methodology and equipment requirements against the applicable network procedure.

Information we will ask for

Network and test location
pipe material and diameter
SDR or wall thickness
Section lengths
Test pressure
Site layout drawing

Arrangement Checks

Main cleared and dried as required
Flange ends installed
Compressor on site suitable for pressurisation of the pipeline
Suitable site access

PROJECT INFORMATION

Bring us the pipeline.

We will plan the evidence.
