Pipeline asset owners now have the opportunity to realise large area monitoring of their pipework in order to detect damage due to corrosion. Guided Ultrasonics Ltd offers a range of products to perform this type of area monitoring for corrosion, which allow detection at the onset of any issues with the potential for 100% POD, zero false calls, and measurement of corrosion rate. Access to the pipe is only required once at installation, thereafter the safety risks and economic costs are avoided. This month’s front cover shows two gPIMS® sensors from Guided Ultrasonics Ltd installed on 14‑inch pipelines. To perform a test a technician plugs a gPIMS Collector instrument into the connection box and the acquisition of data begins. Due to the excellent repeatability of the gPIMS® sensors, this guided wave data can be directly compared to previously captured data allowing small changes in pipeline condition to be identified.
