subject: Ndt Technique Is The Best Way Of Detecting Faulty Materials [print this page] With the huge advancement and innovation of numerous mechanical units, it has also become an easy, cost effective and time saving procedure to check materials, components or systems for any sort of damages. Well! This method today is called the Non-destructive testing and is used widely by industries like electrical, medical, forensic, aeronautical, automotive, construction, power plants, railways and any more.
Companies used to spend a hell lot of time and money behind product evaluations, but with the gradual existence of these NDT laboratories, the industries can save money as well as time in research, product evaluation and troubleshooting. Though, you will find most of these testing laboratories in Massachusetts; presently they are being established in every corners of the U.S.
NDT techniques are mainly, but here we are going to talk about only three of its testing types. To start with, Hydrostatic testing is one most important testing used in this business. This is mainly done to check for leaks and burst pressure in pipeline, gas cylinder, boiler and other sort of plumbing. Hydrostatic testing is useful to determine the durability of the vessels or pipelines and thereby maintain a safety standard.
These NDT laboratories also specialize in Ground Penetrating Radar (GPR) testing. The GPR of concrete is done to detect voids, cracks, rebar location and changes in materials. It is a geophysical method where a power radio signal is transmitted into the ground. As the wave hits a buried object with different characteristics, the receiver records the variations in the reflected wave.
Liquid penetrant testing is a cost effective as well as popular testing method to locate any cracks, voids or defects in all non-porous materials like metals, plastics, ceramics, etc. Liquid penetrant testing is also done to detect wielding defects, leaks, surface porosity and cracks.
These testing laboratories in Massachusetts also deal in bend testing. This helps in determining the ductility of the material when it is bent over a certain radius. After the bend, the material is inspected to detect any cracks on the surface. Bend testing has therefore become a must in metallurgy industry.
There are also several other types of testing like ultrasonic testing, radiography, magnetic particle testing, Eddy current testing, positive material identification and many.
