A NATA-accredited pressure testing company who specialise in conducting pipeline strength, leak and yield tests were commissioned by a large mining conglomerate to monitor the internal air temperature of their pipelines.
Regardless of whether it holds fluids, gases or solids, the internal integrity of any pipeline is a genuine safety consideration. It is crucial to know what’s going on inside the pipe at any given time, with buried pipelines in particular requiring extensive analysis of on-site data.
Crucially, highly accurate continuous monitoring and logging systems are required to assist in differentiating between temperature fluctuations and potential leaks.
Whilst the company’s core business focuses primarily on insitu solutions that are medium-to-long term, the mining conglomerate had need to only monitor for short periods (3-5 days) before moving to another pipeline.
With no portable, short term monitoring solution as part of their existing product offerings, the company turned to Pacific Data Systems Australia for assistance.
Multiple monitoring points
Pacific Data Systems Australia had long since developed their Pipeline Integrity Testing System for use in pre-commissioning leak tests on gas pipelines. The system assists in identifying fluctuations in temperature along the length of pipeline which could indicate a possible leak – the perfect solution for this monitoring application.
Temperature probes were placed at either end of the pipeline length.
One probe (A) is placed into the soil surrounding the pipeline, whilst the second (B) is inserted into conduit abutting the pipeline, with both wired to a dataTaker data logging unit.
The battery powered system collects data every 5 minutes during the 3-5 day test period, and after testing is complete, the data can be directly downloaded to PC for modelling.
