Advanced Heat Exchanger tube testing - Selection of the best Advanced NDT test method.

LMATS offers the latest Advanced Heat Exchanger tube testing and inspection methods to assess the integrity of your heat exchange tubes thus maximising production and the life of your heat exchanger. These Advanced Heat Exchanger tube offer traceable and archiveable records that enable the following of a "Discontinuity" to a point where maintenamce is required.

Refer to the following paradigm for selection in the tables below of the best NDT - Non Destructive Test method for your heat exchanger tube integrity assessment and remaining life measurement.

Expertise: 

Compared to conventional eddy current testing, all other advanced test method instruments and probes are complex and expensive and requires highly trained, skilled and experienced technicians.

LMATS uses Eddyfi Ectane 2 unit for these advanced test methods.

LMATS professionals are trained and experienced in all of the advanced tube testing methods.

LMATS offers Advanced Heat Exchanger tube testing and inspection using the latest Advanced NDT Inspection  Solutions from our Melbourne, Sydney, Brisbane, Albury, Malaysia and India laboratories.

LMATS regularly performs Advanced Heat Exchanger tube testing and inspections in VIC - Victoria, NSW - New South Wales, QLD - Queesnland, QLD - Brisbane, SA - South Australia, TAS - Tasmania, NT - Northern Territory, WA - Western Australia and some of the countries around the world.
