CORROSION INSPECTIONS
ON METHANE PIPELINES

Recent news events highlight the importance for both the managing authorities of methane distribution networks and the owners of diagnostic monitoring of the corrosion level of pipelines.

The method developed by Centrotest allows for the inspection of both the surface part of the network and, more importantly, the buried or encased in concrete sections. The non-visible part of the pipelines, in fact, is not accessible with standard inspection methods and is also more prone to potential leaks or significant reductions in the thickness of the base material. Such anomalies could lead to particularly serious disastrous events.

Our company’s forty years of experience in non-destructive testing, particularly in corrosion monitoring, has led to the development of new methodologies capable of assisting and supporting both public authorities and private individuals who need to verify the safety of their pipelines. This type of inspection is especially suited for pipelines installed over 30 years ago, which do not meet current safety standards and may be more susceptible to corrosive phenomena.

ADVANTAGES

  • Inspection of methane pipelines or other unstable and explosive gases (hydrogen) in industrial facilities;
  • Inspection of methane pipelines or other unstable and explosive gases in power plants;
  • Inspection of methane pipelines or other unstable and explosive gases in inaccessible areas or underground;
  • Inspection of methane pipelines within urban distribution networks;
  • Any type of steel pipelines can, of course, be inspected.

ADDITIONAL INSPECTIONS

To further investigate the corrosive phenomenon or the presence of other anomalies, our company is also capable of performing traditional inspection techniques, such as:

  • Thickness measurement of methane pipelines using ultrasonic thickness gauging;
  • Weld inspection of methane pipelines using liquid penetrant or magnetic particle methods;
  • Volumetric weld inspection of methane pipelines using radiographic and ultrasonic methods.
