Ultra High Speed Condenser Tube Inspection
 This newsletter discusses the inspection of 15,000 Stainless Steel Condenser Tubes, 51’ long. Under-Deposit Corrosion has caused pinholes Stainless Steel Tubing. However, the plant is not able to find these tiny pinholes while conducting off-line hydro or dye testing. TesTex identifies tubes with this flaw mechanism, which are then cut out for destructive verification.

Boiler Reheater Tube Scanning Using LFET
This newsletter discusses an inspection on Utility Boiler Horizontal Reheater Tubing where the LFET scanners needed to be downsized to fit between tubes with ½” spacing between tubes. TesTex identified several tubes with ID pitting; tubes were cut out and sectioned to verify the pitting.

Pitting in Boiler Generating Bank Tubes
 A large Chemical Plant in Eastern Tennessee was experiencing Boiler Generating Bank Tube Failures due to ID Pitting and Longitudinal ID Grooving. TesTex detects pitting using the TesTex Eagle 2000 Plus RFET Inspection System; pitting is verified using a borescope. No grooving is found; lack of grooving is confirmed via borescope.

Vertical Process Tank Inspection via Magnetic Crawler
A large Chemical Plant near Louisville, KY. suspected that pitting was occurring on an inaccessible section of a Carbon Steel vertical process tank. The area of concern was twenty feet higher than could be accessed by platform or ladder. TesTex used the TesTex Viper Magnetic Crawler to conduct the inspection. Areas of thinning to as low as 0.088” remaining out of nominal 0.250” wall thickness were found.
