Application Note: Evaluation of Circumferential Cracking in Non-Magnetic Heat Exchanger Tubes - DefHi Probe [PDF Download Available]

Eddyfi Technologies Eddyfi Technologies ジャパンオフィス
Heat exchangers are used to heat and cool various fluids across a wide range of industrial sectors. This is particularly important for the power generation and petrochemical industries, where equipment reliability is of utmost importance. Standard ECT bobbin probes often struggle to detect circumferential cracks, posing challenges in many cases, but the DefHi probe offered by Eddyfi Technologies can identify various complex shapes inside heat exchanger tubes, allowing for the accurate detection of small circumferential cracks in the tube sheet, sizing, and evaluation of characteristics. Additionally, the inspection speed is eight times faster compared to rotating probes. The DefHi probe is less affected by changes in speed, making it usable regardless of the presence of a mechanical probe feeding device.

Please take a look at Fukuda's air leak tester!

  • NEW
  • PRODUCT

What is an Air Leak Tester? An "Air Leak Tester" is a device that pressurizes the inside (or outside) of a sealed workpiece with air and determines the presence of leaks based on pressure changes. When a master with no leaks and a workpiece with leaks are pressurized, the pressure on the workpiece side decreases, creating a pressure difference between the two. By measuring this pressure difference, the presence of leaks can be determined. Generally, differential pressure air leak testing is widely used, but Fukuda also offers products that utilize direct pressure leak testing and flow meters according to the leak rate, in addition to differential pressure leak testers. Since the air leak tester uses air as the measurement medium, it incurs no running costs and is environmentally friendly.
