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.

detection of general corrosion
Advantages
- No Direct Surface Contact Needed
- Corrosion Detection on-stream
- No Surface Preparation Needed
- Saves time, Costs and risk
- loose rust, scale, paint, coating and the stored or transported product do not influence the examination results, if these items have no electric conductivity and/or magnetic properties
- No unnecessary destruction of insulation or other
- know Status on interior/exterior of equipment
- Know what is happening before a maintenance shutdown
