Case Studies

An Australian LNG Company has many gas field riser pipes in remote locations. The risers are wrapped in various mediums depending on the chosen wrap technology at the time that they were constructed. Currently, the LNG Company policy is to excavate the risers and strip the wrap to visually inspect the pipes for external corrosion.

Assessing steel culverts for corrosion using conventional wet-coupled ultrasonic instruments presents significant challenges. The location and size of these structures often necessitate scaffolding or complete road closures to achieve proper sensor contact with the substrate using couplant. Additionally, due to the presence of sprayed concrete on some areas of the galvanized steel walls and heavily corroded sections, it is not possible to fully conduct the inspection with conventional wet-coupled ultrasonic equipment.

A leading petrochemical company has successfully integrated CODA for on-site inspection and maintenance within its facilities in Nigeria. CODA serves as a vital tool for spot thickness measurement across conditions, including high-temperature environments.

Bolts and screws are one of the most common joining techniques, being able to attach any two materials, even if they are different. Bolts are used in most critical and demanding industries, including infrastructure, power generation, oil & gas, petrochemical, mining, construction, transportation and so forth.

A leading UK resource management company faces the high-stakes challenge of maintaining boiler integrity within its London-based Energy-from-Waste (EfW) facilities. Because these boilers incinerate waste at extreme temperatures ($800$ to $1,100$ °C) in highly corrosive environments, the thousands of internal tubes are susceptible to rapid wear. Constant monitoring of tube wall thickness is critical, as a single leak would force an immediate process stoppage, leading to significant plant downtime and substantial financial losses.

In railway industry, it is crucial to monitor the state of rolling stocks and rail track components in order to avoid unexpected and long downtimes and most importantly, ensure safety of the passengers. In addition to production errors, rail wheels face extreme conditions such as high speed and high temperature mostly caused by braking force. Increase in residual stress is one of the most important consequences of being subjected to those conditions and therefore residual stress value should be measured reliably in order to avoid catastrophic failure of these components due to cracks or fatigue.
