What is Electromagnetic Testing Inspection? Electromagnetic testing inspection is one among the nondestructive testing (NDT) which make use of electromagnetic induction techniques to identify and characterize surface and subsurface defects in conductive materials. This inspection mainly contains three types of testing such as Eddy Current testing ,...
All objects that have a temperature above the absolute zero (-273 C) will radiate some amount of energy in the form of infrared rays. These infrared radiations emitting from objects are not visible to the human eye and it is in the form of heat. Thermography...
Non destructive testing methods are used to determine the integrity of a structure or material without physically disturbing it. Non destructive testing methods don’t require the industrial process to stop for conducting testing. This makes NDT the most desired testing method for structures and equipment...
Acoustic emission testing is an NDT technique which is undergone when a material deforms under stress. AET detects and monitors the release of ultrasonic stress waves from the restricted sources. When a piece of sample is subjected to an external stimulus, like change in pressure, temperature...
API 2201 provides detailed guidelines for safely conducting the hot tapping operations on machineries in petrochemical industries. To expand or modify piping systems in the petrochemical industry, new connections to existing pipelines have to be made. Earlier, to make such connections in piping systems, the whole...
API 1104, Standard for Welding Pipelines & Related Facilities, provides guidelines for the gas and arc welding of butt, and fillets in carbon or low-alloy steel piping used in the compression, pumping & transmission of petrochemical and gas. It is applicable to new constructions and...
Lasers can be used to generate and measure ultrasonic waves in materials. Laser based NDT methods came to acceptance with an increase in the use of composite materials and sandwich structures in industries. These types of structures required high speed and large area inspection for...
What is Time of Flight Diffraction (TOFD) Testing Method in NDT ? Time of flight diffraction is a reliable non destructive testing method mainly used to find flaws in the welds. Like all other ultrasonic testing methods, TOFD uses ultrasonic pulse to locate the irregularities. What makes...
What is Neutron Radiography Testing Neutron radiography technology is also called Neutron Imaging, Neutron Tomography or else N-Ray Radiography. This is a powerful NDT method because of the neutron’s properties. It allows imaging of materials which are hydrogenous like oil, plastic, water, rubber, explosives etc, which...
Ground Penetrating Radar (GPR) technique in NDT is used to diagnose and evaluate the quality of reinforced concrete. Due to the complicated properties of reinforced concrete, usual non destructive testing methods like ultrasonic testing and infrared ray testing cannot be used in the most testing site...
