Detection of Corrosion and Wall Thinning in Carbon Steel Pipe Covered With Insulation Using Pulsed Eddy Current

Differential Hall-sensor Pulsed Eddy Current Probe for the Detection of Wall thinning in an Insulated Stainless Steel Pipe

Development of Pulsed Eddy Current Testing System for Wall Thinning through Insulation with Ferromagnetic Cladding

Corrosion is one of the important factors in equipment failures. Wall thinning can be used to evaluate corrosion conditions. However, most of equipments are coated with insulations in order to elevate the energy efficiency. Pulsed eddy current (PEC) testing technique can be used to measure wall thinning through insulation. But when the insulation outside is wrapped with galvanized steel, PEC si...

gas pipeline corrosion mapping using pulsed eddy current technique

oil and gas transmission pipelines are critical items of infrastructure in providing energy sources to regions and countries. steel pipes are commonly used which can be subject to both internal and external corrosion. this paper presents an advanced nondestructive inspection technique for detection of oil-gas pipeline corrosion defect. the pulsed eddy current (pec) method has been successfully ...

Corrosion Steel Inspection under Steel Plate Using Pulsed Eddy Current Testing

Pulsed eddy current inspection techniques were derived from the conventional eddy current testing technology, based on the fundamental principle of an eddy current coil, but using periodic ultrasound pulses. The authors first introduce the principle of pulsed eddy current inspection and some experimental measurement results using pulsed eddy current equipment. This technology can be applied to ...
