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.

Fast, Accurate, Traceable, and Archivable a digital paper trail


It is as easy as 1-2-3

1 - Select the Tube Material and Tube Type [  Table A ]
2 - Select the Discontinuity Sought and Sensitivity Criteria [ Table B ]
- See Suitability
