Nondestructive testing – NDT inspections are crucial for assuring and controlling the quality of components and structures during manufacturing and in-service inspections. Destructive and Nondestructive tests are important part of quality assurance plans to satisfy the client requirements. Destructive tests-DT has limited applications as the product being tested is damaged or destroyed and hence makes tested material seldom useful.

Nondestructive Inspections – NDT tests will test the materials, structures and components without causing any damage and does not destroy or damage the materials under testing and materials tested can be used for the intended purpose. NDT inspections are important for functioning and to ensure safety of engineering structures under operation. NDT tests are also used in in-service inspection of process plants, boilers, pressure vessels, aircraft structures and lot more engineering structures. Today, NDT Technology can prevent catastrophic failures that are caused due to fatigue, thermal stresses, corrosion, creep and other damage mechanisms by detecting flaws in early stages of life.

2. Crack detection by Magnetic Particle Inspection Methods at NDT labs:

Magnetic particle testing of rings

Facilities at MPI testing Labs: Yoke type, Prod type, and Stationery type – Central Conductor, Head Shot and Coil techniques.

Testing equipment at our MPI testing labs are specially designed to meet international standards and codes on Magnetic particle inspection of Automotive, precision components, general engineering and aerospace applications. Trinity NDT level II certified engineers are well trained to perform inspections with great level of accuracy and repeatability. Magnetic particle testing/crack detection of components and materials can be performed both on site at customer works and at our labs depending on size and quantity of components tested.

Prod type MPI testing technique is suitable for rough castings in foundry shops and weld joints in fabrication shops. Prod type equipments are less suitable for finished components, as the surfaces can be damaged due to accidental arcing during MPI testing. Yoke type testing technique is frequently used for testing finished components with great accuracy. Both fluorescent and non-fluorescent techniques of Magnetic particle testing are employed based on requirements of Nationals, International standards, codes, specifications or customer specifications. Central Conductor testing techniques are suitable for testing of hollow components such as pipes, tubes, cylinders, sleeves and other components to inspect for cracks on inner surfaces as well as outer surfaces. Coil type testing technique is used for testing large number of components for circumferential cracks and other discontinuities.
