Radiographic Testing or Industrial Radiography is a Nondestructive Testing (NDT) method of Inspecting Materials for hidden flaws by using the ability of short Wavelength Electromagnetic Radiation (High Energy Photons) to penetrate various materials.

Dye Penetrant Testing: is a widely applied and low-cost inspection method used to locate 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; PT 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 (Color & Fluorescent)

 

 

Ultrasonic Testing: The use of very short ultrasonic pulse-waves with center frequencies ranging from 0.1-15 MHz and occasionally up to 50 MHz which are launched into materials to detect internal flaws or to characterize materials. A common example is ultrasonic thickness measurement, which tests the thickness of the test object, for example, to monitor Pipe work corrosion

 

Magnetic Particle Testing: is a Non-destructive testing (NDT) process for detecting surface and slightly subsurface  discontinuities in ferromagnetic materials. The process puts a magnetic field into the part.

The presence of a surface or subsurface discontinuity in the material allows the magnetic flux to leak; ferrous iron particles are then applied to the part. If an area of flux leakage is present, the particles will be attracted to this area. The particles will build up at the area of leakage and form what is known as an indication.

 

 

Visual Testing (VT): It is the process of looking over a piece of equipment using the naked eye to look for flaws. It sometimes requires no equipment except the naked eye of a trained inspector. Visual inspection can be used for internal and external surface inspection of a variety of equipment types, including storage tanks, pressure vessels, piping, and other equipment.

 

 

Vacuum Box Testing: Vacuum box testing is a non-destructive examination used when trying to locate weld seam leaks. A vacuum box and a compressor create a high or low pressure vacuum while a detergent solution is applied to the test area.

The detergent bubbles, making leaks visible within the created pressure envelope. All inspections are conducted within the parameters of ASME Section V Article 10, Appendix II or to client specifications.

 

 

Bore Scope Inspection Technique: It is a precise optical instrument with built-in illumination. It can be using visually check internal areas and deep holes and bores.

Used to locate imperfection not limited to wear, corroded area, material loses, etc..,  

Bore –scopes inspection are commonly used in heat exchanger, pipes and anther industrial applications.
