Electromagnetic testing (ET) is a non-destructive testing method that uses the principle of electromagnetic induction for the detection of flaws in surface and subsurface levels. Eddy current testing (ECT) is a type of electromagnetic nondestructive testing (NDT) method. However, the terminologies for ET testing and ECT are often interchangeably used in industries for their same NDT principle. ...
Oil and gas are drilled and pumped from the depths of the earth during hydrocarbon exploration. Before these hydrocarbons are transported to various destinations around the world, they are stored above ground in storage tanks. Companies rely on the integrity of storage tanks to keep their assets protected from the elements. Hence, the importance of storage tank inspections. Storage tank ...
The FAA has issued a new airworthiness directive (AD 2020-26-16) for certain Piper Aircraft models following a fatal crash caused by a wing separation from fatigue cracking on the lower main wing spar cap. Part of the requirements specified in this AD includes inspecting the lower main wing spar bolt holes for cracks. Accordingly, Piper Aircraft, Inc. has issued a service bulletin SB 1345 that ...
In the aerospace industry, there are two major components to any aircraft fatigue inspection process: time and accuracy. In order to ensure safety while maintaining costs and reducing downtime, inspections and testing have to be fast and efficient without sacrificing accuracy or thoroughness. This combination of benefits has led to a widespread embrace of nondestructive testing (NDT) for ...
Eddy current testing is a fast, accurate, chemical-free method for detecting a variety of surface and sub-surface defects, including cracks, corrosion, and heat damage. It’s a proven technology for inspections of welds, rivet holes, tubing, and other ferrous and non-ferrous components in aerospace, oil and gas, and other ...
Many of the most complex, large-scale systems also depend on the successful functioning of the smallest components and carefully-calibrated coordination. Tiny flaws or small layers of corrosion can cause huge problems. To ensure product reliability, manufacturers and asset owners run tests frequently. Both wall and coating thickness measurements are among these tests. Coating thickness ...
Welds are a critical element in too many large scale infrastructure, manufacturing, and transportation projects to be easily listed. Marine shipping hulls, the steel supports for buildings, oil storage tanks, and the steam turbines that generate power in both fossil and nuclear power plants are just a few of the areas where welds can be found and should illustrate how vital quality welds are for ...
To achieve a robust inspection, consider ultrasonic testing (UT) and eddy current testing (ECT). Both methods can cover more testing ground in less time and detect more flaws than other NDT options. ...
When it comes to NDT for corrosion detection, choose an ultrasonic testing solution including a scanner or an eddy current array solution including an instrument and flexible probe. ...
Eddy Current Array for Train Wheel Inspections Efficient train wheel inspection procedures ensure that train wheels can withstand heavy stress. ...
Nuclear experts may also use another NDT method known as eddy current testing (ECT), which can test such materials as steam generator tubing without interfering with the structural integrity of steam generators. Eddy current instruments can also find surface and sub-surface abnormalities, as they are easily able ...
Eddy Current Testing of Wind Turbines Eddy current testing is another viable and increasingly popular approach to wind turbine NDT. ...
Eddy current technology uses electromagnetic currents to map the surface and near-surface areas of conductive materials. ...
But can eddy current testing (ECT) detect cracks more efficiently than other methods? ...
The Zetec booth (#2001) will feature innovative and proven NDT solutions, including: New Surf-X array probes with the MIZ-21C handheld eddy current instrument. This combination delivers one of the industry’s most portable eddy current array solutions for surface inspections, with performance that can ...
Steam generator tubes are among the most vital safety barriers within pressurized nuclear reactors (PWRs), and underlying defects can degrade the tubing material and damage the entire steam generator, causing severe problems that can endanger crew members and the public. Using cutting-edge eddy current testing (ECT) instruments and techniques ...
Another module could use the magnetic-inductive and eddy-current measurement techniques for non-magnetic coating on such metals as copper or zinc. Tip #3: Use Eddy Current Testing When Appropriate Eddy current testing (ECT) can also be a useful approach to measuring conductive coating ...
Bokena has eddy current machine for sale! GTET-02 Cylinder Liner Eddy Current Testing Machine Introduction 1. ...
It can also be used to spot-check welds for flaws. Eddy Current Motor Vehicle Safety Inspection Technology Eddy current technology works most effectively near the surface of conductive materials. By inducing a magnetic field into the material and measuring the result, eddy current ...
