Eddy Current Inspection

is a sensitive and reliable method for detection of surface cracking beneath coatings and for weld inspection. Portable, battery operated equipment means most test locations can be easily accessed, including sub-sea applications. Pulsed Eddy Current is a unique corrosion survey tool that allows ferrous pipes and vessels to be surveyed through thermal insulation under the following demanding circumstances:

• Without disturbing the insulation or coating
• When insulation is aluminum, stainless steel or low alloy steel clad
• While plant is in operation
• When equipment is hot < 500°C or cold > - 100°C
• When insulation is wet
• When object surface is rough or encrusted
• When insulation is rough or heterogeneous
• When insulation is wire mesh reinforced

Designed as a fast survey tool, a two-person crew can survey and store up to 1,000 points per day, depending on accessibility. Equipment demonstrates excellent repeatability and is well suited for either baseline surveys followed by periodic monitoring or for on-stream inspection of vessels and pipelines prior to major plant shutdowns. Survey reports can be generated on site at the end of the working day.
