For inspection on water, fuel, steam and grey water systems, the LIXI Profiler provides excellent accessibility, portability, radiation safety and is useful in tight spaces.

Erosion/Corrosion: Internal degradation of pipe wall thickness due to high velocity material impacting the pipe. Usually occurs at flow direction changes such as elbows, tees, and reducers. The impacting material can be solid particulates entrained in a liquid process stream or liquid droplets entrained in a vapor process stream.

Corrosion Under Insulation (CUI): CUI in a water distribution system is dependent on the ambient humidity, the temperature of the piping, and whether or not the piping is exposed to the elements. Once water is in contact with the carbon steel pipe within the insulation, external corrosion will continue to progress until arrested.

Any water that has entered the insulation will either freeze on the pipe if it is operating at or below 32F, or it will remain a liquid that may travel considerable distances from where it was first introduced into the insulation. Ice will not corrode the surface of the carbon steel piping, but liquid water will seek the lowest and/or coldest point in the piping system and remain a constant threat to the integrity of piping.

Chemical corrosion: Constituents of fuel, grey water, waste water, and process chemicals may contain highly reactive chemical components that can react with the chemical components of the marine piping. This type of degradation may cause localized internal pitting or general wall loss occurring relatively uniformly on the internal diameter of the pipe that is in contact with the process fluid.
