Wax Rich Lines Inspection

Wax in pipelines is a common phenomenon, which can cause serious consequences for the ability to perform in-line inspections (ILI). Crude oil lines often have high contents of wax present, deposited on the pipe wall or transported within the pipeline medium. The presence of this wax can seriously affect the performance of a chosen ILI tool and can lead to a dramatic deterioration of the quality of the inspection data, thus endangering the purpose of the inspection and leading to the waste of time and money. 

Significant amounts of wax or paraffin deposits can still be in a line, even after lengthy and careful cleaning. Issues such as the pour point can lead to wax falling out of the oil, immediately after a cleaning run, making it next to impossible to achieve a completely clean wall prior to launching an intelligent inspection tool.

NDT Global offers an intelligent survey using a wax configured ultrasonic inspection tool, specifically developed for pipelines with high wax content. The NDT Global solution is simple in its principle, by allowing bypass of the pipeline medium, the liquid can be used to flush the ultrasonic sensors to keep them clear from the build-up of wax deposits. 

This solution has proven an effective modification and has significantly helped pursue NDT Global's target of 100% first run success.

EVO Series UMP

NDT Global offers high-resolution pinhole and pitting (UMp) metal loss inspection service as standard.

The UMp service reliably detects defects and sizes as small as 5 mm (0.2 in) diameter, which represents a two-fold improvement in the minimum sizing threshold, from the previous entry level ultrasonic service of 10 mm (0.4 in).
