Pipe Wall Assessment


Spectrum XLI Pipe Wall Assessment (PWA) is a screening tool for ferromagnetic pipelines that can identify stress concentration zones through the measurement of magnetic field changes.

Pipe Wall Assessment
provides an additional source
of integrity data

Spectrum XLI PWA is a screening tool for oil and gas pipelines that can provide pipeline condition information to help inform and direct higher resolution assessment programs. In addition, PWA can detect locations on a pipeline that may be the subject of significant geo-hazard induced stress where no defect on the pipe wall is present and detectable through traditional inline inspection. PWA should be used in combination with other pipeline integrity tools to identify areas at risk of failure through the measurement of magnetic
field changes.

Why Choose PureHM?


Above-ground surveys offer an operator inspection flexibility
and the ability to assess
unpiggable pipelines.


The information provided by PWA technology cannot be replicated by traditional integrity tools.


PWA contributes to a complete, industry-leading integrity program that limits risk.
