PEC

Pulsed Eddy Current

PEC works on low alloy carbon steel by briefly magnetizing the ferrous metal through the insulation.

PEC may be used on larger diameter piping and pressure vessels with excellent results. The wall thickness of piping and plates should be between 0.25” and 2.5”. Insulation thickness may be up to 8”. Jacketing thickness for stainless steel, aluminum, and galvanized steel should be less than 1mm.

When determining the best method for your industry and company requirements, there are many factors that should be evaluated. Below is a high-level baseline that is a great place to start, including standard requirements and (PEC) Pulsed Eddy Current’s ability to meet these requirements.

REQUIREMENT RESULT
Safety
I need daily operations to continue uninterrupted during facility inspection.

There is no risk of radiation with PEC, it is 100% safe to resume operations while testing

Meets need
Preparation
I do not have/do not want to commit resources to prepare pipes for inspection.

No insulation (up to 8”) removal or surface prep required. Requires uniform insulation thickness for best results. Suitable for magnetic steels only.

Meets need with exception
Data
I need accurate information about the state of tested pipe and indications of threat.

Excellent results on pressure vessel shell and heads for generally corroded areas. Most appropriate for larger diameter vessel shell & heads. Moderate detail. Cannot measure water or ice in insulation. Results are affected by nearby flanges, valves, pipe supports, or other ferrous steel components. Technicians can inspect up to 50 locations per day.

Meets need with exception
Scope
I need all piping and vessels in my facility or designated inspection area tested.

Not appropriate for small diameter piping.

Meets need with exception
Timeliness
I need vulnerabilities in my system identified quickly.

PEC is able to provide real-time results for immediate further investigation where necessary
