Need for NDT

A Doctor testing a patient; a Scientist/Engineer/Technician tests the fitness of the material.. Thus, NDT is necessary. The need to ensure safety, NDT can be used to improve output and profitability. A component /structure/machine can be tested many times using several types of tests through the complete life cycle to ensure its continued integrity. Choosing the right method and techniques is an important part of the performance of NDT

Industry Parlance

NDT is the keyword for Quality in industries.

NDT is used in a variety of settings that covers a wide range of industrial activity, with new NDT methods and applications, being continuously developed. NDT services are not only integrated with Asset Integrity Management (AIM) solutions, but also with Material Testing laboratories and seamlessly fit into Supply Chain services

Industrial plants such as Nuclear, Petrochemical, Power, Refineries, Pulp and Paper, Fabrication shops, Mine processing and their Risk Based Inspectionprogrammes.

NDT supports various kinds of engineering activities like mechanical, automotive, civil, electronics and many others. Hence it is utilised by a gamut of industries that deal with manufacturing processes using any or all of the above mentioned engineering process and further beyond.

NDT Basics

NDT-Destructive Testing is the Synergism of Science and Engineering to create methods of testing that leave the item under test totally undamaged. This means that the component can continue to be used and that the non-destructive Testing method has done no harm. NDT can be used to ensure the quality right from raw material stage through fabrication and processing to pre-service and In-service inspection. Apart from ensuring the structural integrity, quality and reliability of components and plants, today NDT finds extensive applications for condition monitoring, residual life assessment, energy audit etc.
