PEC is a fast, accurate and reliable way of surveying ferrous pipes and vessels through their thermal insulation. PEC does not disturb insulation or coatings and provides accurate results through aluminum, stainless or galvanized steel claddings. Further, insulation may be hot, cold, wet, rough, encrusted, irregular, heterogeneous, or even wire mesh. Through its excellent repeatability, PEC is ideally suited for baseline and periodic monitoring services.
