Near Field Testing (NFT)
Fast, accurate detection of internal corrosion in non-ferromagnetic tubing.
Near Field Testing (NFT) is designed for non-ferromagnetic materials, such as air coolers and heat exchanger tubing. It provides accurate detection of internal corrosion and thinning, delivering results quickly without the need for complex calibration.
NFT excels at locating ID-side damage near the tube sheet, making it ideal for air-finned cooler bundles where rapid screening of hundreds of tubes is required during a tight turnaround window.
