Non-Destructive Testing (NDT):

Non-Destructive Testing (NDT) is the examination of an object or material with technology that doesn’t affect the future usefulness. NDT Techniques do not harm or destroy the object under test. NDT can provide an excellent balance of quality control and cost effectiveness without affecting manufacturing yields.

The term NDT includes many methods that can:

  • Detect Internal or External discontinuities (Defects)
  • Determine structure, composition or material properties
  • Measure Geometric characteristics

Non-Destructive Testing (NDT) is also known as Non-Destructive Evaluation (NDE) or Non-Destructive Inspection (NDI).

NDT training requires a lot of knowledge and experience in several skills before you start exploring employment options. You don’t only need to have theoretical knowledge about the subject, but also you need a lot of hands-on training which you will get upon joining BlastCorr India (BCI)!

Thermal/Infrared Testing (IRT)

Infrared (IR) technology is widely used in the oil and gas industry as an inspection tool for condition monitoring and predictive maintenance. It is advantageous over traditional visual inspection and other tools because infrared technology does not have to be in contact with the equipment being monitored.IR thermography is a form of nondestructive testing that measures temperature variances of a component as heat (i.e., thermal radiation) flows through, from, or to that component. IR thermography is also generically known as IR testing, thermal testing, thermal imaging, and IR thermometry.

Positive material identification (PMI)

The method is utilized for quality control and safety compliance, and is an integral part of both production and asset integrity management across many industries including oil and gas, power, chemical, pharmaceutical, nuclear, aerospace and fabrication. Positive material identification can prevent potential product failure in manufacturing. At oil and gas, power generation and pharmaceutical plants, pre-service and in-service inspection of critical components and welds with PMI can prevent breakdown and its costly consequences.

PMI can:

  • • Ensure products/components have been manufactured using the correct alloy
  • • Find potentially mixed-up alloys
  • • Identify if the wrong material has been used
  • • Ensure material conforms to the correct standard and specification (both customer and industry)
  • • Ensure welded components have used the correct filler material

Ultrasonic thickness gauging (UTG)

Ultrasonic thickness gages work by very precisely measuring how long it takes for a sound pulse that has been generated by a small probe called an ultrasonic transducer to travel through a test piece and reflect back from the inside surface or far wall. Because sound waves reflect from boundaries between dissimilar materials, this measurement is normally made from one side in a "pulse/echo" mode.

Ultrasonic Thickness Gauge which can be used for a number of applications such as:

  • • Checking the specification of materials that have been delivered
  • • Measurement of in situ materials, through coatings if required
  • • Measuring the remaining wall thickness due to corrosion
  • • Power generation - measurement of wall thickness in pipelines, pipe elbows, base materials (semi-products), as well as thickness of near-weld zones in pipe joints;
  • • Aviation - measurement of wall thickness of aircraft steel parts and portholes (windows) with one-side access to the test item;
  • • Pipe industry - measurement of pipe wall thickness; detection of laminations in the pipe wall; recognition of thinned spots in the pipe wall;
  • • Oil and Gas industry - measurement of wall thickness of pressurized vessels, above-ground pipeline branches, underwater line manifolds of main gas pipelines, gas and oil tanks, as well as pump and valve bodies;
  • • Railway - thickness measurement of railway wheel disks during their production.
