Range of NDT testing for the fuel and rail industries


Non-destructive (NDT) testing

Fuel tanks and associated pipework must be regularly tested to check their integrity and prevent the accidental discharge of harmful fuel. NDT uses non-invasive techniques to accurately check tank and line integrity without the need for any deconstruction. LCM’s NDT testing service is used to test clients’ tanks, railway wagons and other critical fuel storage infrastructures. Following testing, a comprehensive report will be produced that may be used to satisfy asset management processes, insurance, or compliance inspection by regulatory authorities.

Ultrasonic NDT testing

Ultrasonic testing (UT) is one of the three NDT methods used by LCM’s trained technicians. UT’s high-frequency sound waves are used to establish the thickness of the metal in the fuel tank and identify any defective areas or welds.

Magnetic flux testing

Magnetic flux testing or magnetic flux leakage (MFL), as it is often called, is a form of NDT testing which uses a magnetic field to measure variances in the structure of a metal pipe. Powerful magnets are placed around the pipe and any weakness are indicated by a change in the magnetic field which the operator will identify and record.

Dye penetrant inspection

Dye penetrant NDT testing or liquid penetrant inspection (LPI) is typically used to check stressed areas of a metal fuel tank, such as previous welded repairs or welded joints. The suspect area is coated with dye and an ultraviolet light shows up any non-conformity. This might indicate a crack or damage which can be further investigated.
