Non Destructive Testing

Conventional NDT Inspection Services

INAT offers the following NDT services (Conventional) to fulfill the needs of Oil & Petrochemical and Industrial operations.

This technique involves the use of penetrating gamma or X-ray radiation to examine parts and products for imperfections. An X-ray machine or radioactive isotope is used as a source of radiation. Radiation is directed through a part and onto 8ilm or other media. The resulting shadow graph shows the internal soundness of the part. Possible imperfections are indicated as density variations in the film.

Ultrason Inspection is a non destructive testing method in which beams of high-frequency sound waves are introduced into materials for the detection of subsurface flaws in the material. The reflected beam is displayed and then analyzed to define the presence and location of flaws or discontinuities.

Magnetic Particle Inspection (MPI) is used for the detection of surface and near-surface flaws in ferromagnetic materials. A magnetic field is applied to the specimen, using a permanent magnet (or) electromagnet to detect imperfections in material, using the following yokes and prods.
> AC Yoke
> AC/DC Yoke

Apart from visual inspection this is probably the oldest and most widely used of all the NDT methods. It can be used on any non-porous material. Its use is confined to the detection of surface breaking defects.

Hardness is the resistance of a material to localized deformation. The term can apply to deformation from indentation, scratching, cutting or bending. In metals, ceramics and most polymers, the deformation considered is plastic deformation of the surface. We will provide all types of hardness measurements like

  1. Brinell Hardness Testing
  2. Rockwell Hardness Testing
  3. Vickers Microhardness

Ultrasonic Thickness Gauging is a widely used non-destructive testin technique for measuring the thickness of a material from one side. It is fast, reliable, and versatile, and unlike a micrometer or caliper it requires access to only one side of the test piece. It will give very accurate results in terms of micrometer and, as per client requirements we can access the painted surfaces and cladding surfaces also.

Positive Material Identification (PMI) is the identification and analysis of various metal alloys by their chemical composition through non-destructive methods.

PMI can be conducted on-site or in the laboratory. PMI helps our customers choose the right materials for their application from this vast market.

In addition to producing high quality radiographs, we are also providing Radiography Film Interpretation Services (RTFI) for clients as per their requirements, we also supply well experienced RTFI Manpower to clients. Interpretation of radiographs takes place in three basic steps:

  1. detection
  2. interpretation
  3. evaluation

All these steps make use of the radiographer's visual acuity. Visual acuity is the ability to resolve a spatial pattern in an image.

Advanced NDT Inspection Services

INAT offers the following NDT services (Advanced) to ful8il the needs of Oil & Petrochemical and Industrial operations.

INAT provides Phased Array Ultrasonic Testing to inspect welds of process equipment, piping and structures (PAUT) offers very reliable detection and sizing capabilities along with a permanent record of ultrasonic inspection.

INAT provides Ultrasonic TOFD to inspect welds of process vessels and piping. TOFD is a reliable and fast advancing ultrasonic technique with good sizing capabilities and higher inspection speed.

INAT  provides  complete  Heat Exchanger  inspection solutions for various tube materials by  following methods.

  • Eddy Current Testing (ET) - for Non- Ferromagnetic Tubes.
  • IRIS (Internal Rotary Inspection System)
  • Any material for accurate wall thickness.
  • Magnetic Flux Leakage Testing (MFLT)
  • For Ferromagnetic and Fin fan Coolers Tubes.
  • Remote Field Eddy current Testing (RFT)
  • For Ferromagnetic Tubes.

Corrosion mapping is a technique which maps material thickness using ultrasonic techniques. Variations in material thickness due to corrosion can be identified and graphically portrayed as an image. The technique is widely used in the oil and gas industries for the in-service detection and characterization of corrosion in pipes and vessels. The data is stored on a computer and may be colour coded to show differences in thickness readings.

Mechanical & Destructive Testing

WPS , PQR & WQT Services

The purpose of WPS is to determine that the welding operations proposed for fabrication can produce welds with required properties for intended application. The purpose of PQR is to select material for specific application and to verify the weldment also meet the design criteria. INAT is providing PQR services from its own mechanical lab facility. The objective of Welder Qualification Test to give maximum confidence that the welds mechanical and metallurgical properties meet the requirements of the applicable code/ specification.
INAT provides the following activities related to welding quality:
