PEC application
Pulsed Eddy Current:
Theory: Pulsed eddy current, or PEC, is an advanced electromagnetic inspection technology used in detecting flaws and corrosion in ferrous materials typically hidden under layers of coating, fireproofing, or insulation, which we call lift-off.
Applications: It is most commonly used to screen for corrosion under insulation, often referred to as CUI, corrosion building up under coatings often referred to as corrosion blister or scabs, flow-accelerated corrosion, corrosion under fireproofing, surface corrosion and more.
Insulation: <150mm , Temperature:<60°C , Thickness:< 60mm. Due to the promotion of “Risk Based Inspection” which needs the thickness data on insulated pipe, PEC can provide useful data without removal of insulation, supporting quantitative data for piping system.
