Spectrum XLI


The Spectrum XLI platform is a complete system for proactive above-ground inspection of buried pipelines.

Spectrum XLI is the most reliable way to collect above-ground survey data

The Spectrum XLI system allows operators to complete multiple above-ground surveys in a single pass of the pipeline. This provides more reliable inspection data, and allows the operator to save money by reducing the number of surveys needed to collect multiple data streams.

PureHM and the Spectrum XLI platform are represented by Allied Engineers in the Middle East region. For more information, please visit the Allied Engineers website.

Spectrum XLI

Using the XLI system, all pipeline data is auditable, streamlined, and delivered as quickly as possible to inform integrity and repair decisions.

Simultaneously, the Spectrum XLI system can collect: GPS/GIS, depth of cover, depth of water, gas leak detection, cathodic protection survey (CP CIPS/CIS), direct current voltage gradient (DCVG), alternating current voltage gradient (ACVG), alternating current-current attenuation (ACCA), soil corrosivity measurements and Pipe Wall Assessment data.

By collecting all data with one solution, pipeline owners receive the results in a single reporting platform, which allows for more informed decision-making and reliable data integrity. This ensures that all pipeline data is auditable, streamlined, and delivered as quickly as possible to inform integrity and repair decisions.
