5 EDDY CURRENT TESTING Eddy Current is a electromagnetic application used in the industry for the inspection of non-ferrous material in such alloys as: Stainless Steel Titanium Brass 90/10 Copper Nickel Inconnels Hast. C-276, B2. Monel-400 etc. Eddy Current has the sensitivity to detect a wide range of corrosion and erosion (Process or Mechanical) such as: Baffle Fretting (Vibration), impingement erosion, tool gouges, corrosion, pitting, stress corrosion cracking, MIC, etc. Copyright 2010 Proprietary Information: no dissemination, use or duplication allowed

6 Eddy Current Array Tubing Technology Eddy current array (ECA) technology is the most advanced technique available to inspect non-ferrous tubing. The array configuration allows high-resolution inspections without compromising on the pull speed. ECA probes can be used to detect and size various types of defects such as corrosion, pitting, and cracking (circumferential and axial). Defects located near or under tube support plates or tubesheets can easily be detected with ECA probes Copyright 2010 Proprietary Information: no dissemination, use or duplication allowed

12 REMOTE FIELD TESTING RFT is a through-wall transmission technique where the electro-magnetic field travels through the tube wall exciter location and once at the receiver location. Any defects located at the exciter and/or receiver location will have an effect on the magnetic field and will be sensed by the receiver coil. Exciter Receiver (Pickup Coil) Ferro-magnetic such as: SA-214, SA-179, SA- 789/2205 duplex, SA-213-T5, T11, SA-178, etc. to name a few.

15 REMOTE FIELD TESTING SIZING & DETECTION OF MICROBIOLOGICAL INDUCE CORROSION (2205 Duplex)

16 SIZING & DETECTION OF STEAM EROSION & CORROSION (STEAM GENERATOR TUBES)

17 IRIS TESTING This technique uses unique water driven rotating mirror to direct an ultrasonic beam, which is reflected 90 degrees to the internal tube wall. The water acts as a water couplant and transmit sound waves from the ultrasonic transducer to the tube wall. Copyright 2010 Proprietary Information: no dissemination, use or duplication allowed

20 NEAR FIELD TESTING NFT is an electromagnetic technique similar to RFT probe except the coils and sensors are much closer together to only pick up the near-field portion of the induced field. The purpose of this application is to detect I.D. inlet erosion/corrosion as well as isolated pitting that normally occurs in air coolers (Fin Fans) Copyright 2010 Proprietary Information: no dissemination, use or duplication allowed
