TT Probe

TT Probe^TM Introducing the world's most advanced ET System for quantification of magnetite exfoliation blockage in stainless steel boiler tubes.

What is magnetite exfoliation flakes and how to detect it? Magnetite tends to exfoliate when going through heat cycles. When exfoliated magnetite flakes fall down inside the tubes, they tend to accumulate in the lower tube bend sections and will eventually cause magnetite blockage in the bends. When the blockage exceeds a certain limit, the tube may fail in the form of rupture. Early detection of magnetite blockage is therefore key to ensuring normal operations.

Russell NDE Systems Inc. has provided a solution, using through transmission (TT) electromagnetic technique for the detection and quantification of magnetite blockage in stainless steel tubes.
