1. UT- Ultrasonic testing utilizes high-frequency sound waves that are transmitted throughout the material being tested in order to conduct a thorough inspection. Ultrasonic inspection can be used to detect surface flaws, such as cracks, seams, and internal flaws such as voids or inclusions of foreign material. It’s also used to measure wall thickness in tubes and diameters of bars.
2. MPI-Magnetic particle Inspection (MPI) is a non-destructive testing (NDT) process for detecting surface and shallow subsurface discontinuities in ferromagnetic materials such as iron, nickel, cobalt, and some of their alloys. The process puts a magnetic field into the part. The piece can be magnetized by direct or indirect magnetization.
3. STEEL WIRE ROPE NDT- Wire rope testing is a form of electromagnetic inspection using equipment designed specifically for steel braided wire rope. Steel rope is used in a variety of applications such as Ropeways, amusements parks, mine shafts, suspension bridges and overhead cranes.Wire rope inspection is a computerized, electromagnetic test of ferrous wire ropes. It detects and measures localized defects or deterioration and loss of material. This method is capable of analyzing both internal and external flaws. Our test method is capable of measuring relative changes in average metallic area of 0.1% and of detecting flaws to 0.05% of nominal rope area.
4. DPT- Dye penetrant inspection (DP), also called liquid penetrate inspection (LPI) or penetrant testing (PT), is a widely applied and used to check surface-breaking defects in all non-porous materials (metals, plastics, or ceramics). The penetrant may be applied to all non-ferrous materials and ferrous materials, although for ferrous components magnetic-particle inspection is often used instead for its subsurface detection capability. LPI is used to detect casting, forging and welding surface defects such as hairline cracks, surface porosity, leaks in new products, and fatigue cracks on in-service components.
5. RADIOGRAPHY TEST:- Radiographic Testing (RT) is a non-destructive testing (NDT) method which uses either x-rays or gamma rays to examine the internal structure of manufactured components identifying any flaws or defects. In Radiography Testing the test-part is placed between the radiation source and film (or detector). The material density and thickness differences of the test-part will attenuate (i.e. reduce) the penetrating radiation through interaction processes involving scattering and/or absorption.
6. Visual Inspection is one of the most common and most powerful means of non-destructive testing. Visual testing requires adequate illumination of the test surface and proper eye-sight of the tester. To be most effective visual inspection does however, merit special attention because it requires training (knowledge of product and process, anticipated service conditions, acceptance criteria, record keeping, for example) and it has its own range of equipment and instrumentation. It is also a fact that all defects found by other NDT methods ultimately must be substantiated by visual inspection. VT can be classified as Direct visual testing, Remote visual testing and Translucent visual testing.
7. PMI- Positive Material Identification (PMI) is an on-site examination of security-relevant components in regard to the used material (especially in the field of metal structures). It’s on spot, non-destructive and verifies the compliance of the chemical composition of the materials used. Instead of relying on certificates of composition, regulations force many plant operators to check all the materials used.
8. Field Balancing – Field balancing is a technique used to balance a rotating part in place without removing the part from the machine. The advantages of field balancing are apparent, in that time can be saved by not removing the rotating part from the machine and sending it to a shop for balancing. An additional benefit is realized in ensuring that the rotating part is balanced as installed.When field balancing, one must have access to the rotating shaft and have an area to place trial weights and correction weights.
9. Vibration Analysis is a process that monitors the levels and patterns of vibration signals within a component, machinery or structure, to detect abnormal vibration events and to evaluate the overall condition of the test object.
10. Coating Thickness-Digital Coating thickness test to measure coating thickness on metallic substrates. Electromagnetic induction is used for non-magnetic coatings on ferrous substrates such as steel, whilst the eddy current principle is used for non-conductive coatings on non-ferrous metal substrates.
11. Insitu-Metallography-As an NDE technique, In-situ metallography is considered important for assessing the health of the equipment, which operates under different plant conditions. The acceptance of in-situ microstructure assessment is from the fact that industry needs safe, trouble free.

12. Ferrite Content test-Ferrite testing is to test delta ferrite content in austenitic and duplex stainless steels. Proper ferrite content provides a balance between ductility, toughness, corrosion resistance and crack prevention.
