Non-Destructive Testing

Ultrasonic Flaw Detector, ultrasonic thickness gauging, magnetic particle testing, Dye Penetrant testing, Industrial Radiography, Portable hardness testing (in situ hardness testing)

Ultrasonic Flaw Detector – Detection of internal Flaws in Castings, Forgings, rolled product, and welded joints by Ultrasonic Flaw Detector.
Ultrasonic Thickness Gauging – Wall Thickness by Digital Ultrasonic Machine.
Magnetic Particle Testing – Detection of Flaw at surface and sub surface region by magnetic method for Ferro magnetic materials.
Dye Penetrant Testing – Detection of flaws on material surface by Dye Penetrant method.
Industrial Radiography – Industrial Radiography for flaw detection in welded joints, castings, Rolled products.
Dynamic Portable Hardness Testing – Hardness Testing of large and static engineering installations.

Chemical Analysis

Chemical Analysis of Iron, Steel and Non-Ferrous metals like Aluminium, Copper, Silver, Zinc and alloys like, Brass, Bronze, Gun Metal etc. Chemical Analysis of minerals, Ferro Alloys, ash content of coke etc.

Metallographic Testing

  • Microstructure analysis for grain structure, case depth, grain size, assessment of heat treatment, inter granular and trans granular corrosion, identification of brittle base, carbide precipitation, inclusion ratings.
  • Macro structure for identification of macro defects as inclusions, segregations, dendrites etc.
  • In situ metallography for metallographic work at site for large heat-treated parts, pipes, fired heater tubes, superheater tubes of boilers, boiler tubes, economiser tubes of boilers, welded parts, boiler plate, hot plate, forged & rolled stocks.
  • Scanning Electron Micrography.

Mechanical testing

Determination of physical properties such as UTS, Yield Stress, proof Stress, % Elongation, Reduction in area, Bend, Rebend test, Impact test, Hardness like, Brinell, Rockwell, Vickers and also Hardness at site.
