Magnetostrictive sensor technology proven in process applications

Various tests and operating environments have successfully demonstrated magnetostrictive sensor (MsS) technology.This relatively new technology enables a nondestructive examination (NDE) survey of pipe walls to detect corrosion, erosion, and circumferential cracks.MsS technology is attractive because it can detect corrosion under insulation without removing all involved insulation and detect corrosion in tubing in situ. Particularly, only insulation where the MsS sensors are placed needs to be removed when corrosion under insulation is suspected.For tubing, only limited access to ends of the tubing is necessary for inspection by MsS technology.The distance down the pipe that the MsS wave ...
