Fireproofed Steel Structures

Pulse Eddy Current (PEC) Inspection for Fireproofed Steel Structures delivered by NDT AND PWHT SOLUTIONS PVT LTD – Trusted Global Experts in Non-Destructive Testing Fireproofed steel structures are commonly found in oil & gas facilities, petrochemical plants, refineries, offshore platforms, and critical infrastructure where passive fire protection is applied to carbon steel components to mitigate the impact of hydrocarbon or jet fires. However, the steel underneath is prone to corrosion, and traditional inspection methods require destructive removal of the fireproofing, often damaging the protective layers and increasing costs.

At NDT AND PWHT SOLUTIONS PVT LTD, we provide advanced Pulse Eddy Current (PEC) inspection services designed specifically for inspecting steel structures concealed beneath fireproofing material, without removal or damage.

Why PEC is Ideal for Fireproofed Structures?

Fireproofing, whether cementitious, intumescent, or epoxy-based, makes direct inspection of steelwork nearly impossible using conventional techniques. Visual and ultrasonic methods require partial or complete removal, followed by repair or reapplication.

PEC allows for complete inspection coverage without removing the fireproofing. It works by sending electromagnetic pulses through the fireproofing and interpreting the response from the steel underneath. This method enables accurate detection of wall loss, thinning, and hidden corrosion, even on hot or in-service structures.
