Electromagnetic inspection for detecting corrosion and metal loss in tank floors and ferrous components.

From Inspection Requirement
to Clear Action.

A focused inspection process designed to turn technical requirements into reliable, actionable information.

01

Understand the Requirement

The project-specific requirement that targets the combined application of low-frequency eddy currents with magnetic saturation to detect surface and subsurface defects in ferromagnetic components.
02

Inspect with Purpose

A SLOFEC probe saturates the material magnetically while low-frequency eddy currents are induced into the material, which includes carbon steel material under coatings and linings in storage tank, pipelines, pressure vessel and other industrial components.
03

Analyse the Findings

Evaluates for discrimination of the near-surface and far-surface defects by analysing the phase angle of the eddy current signal.
04

Report for Action

A SLOFEC test report with defect details evaluated against project-specific criteria is issued.
