Eddy Current Tube Standards. Ready
to request a quote for a standard? Here's what we need... What is the material?
(Alloy, OD and Wall) Is NDE supplying the material or will it be
customer supplied? What defects are needed and what size? (most depths are
given in % of tube wall) Is there a specification the standard needs to comply
with? (ASME, etc.) If you have a drawing, or even a simple hand
sketch, please send that along as well. We specialize in custom eddy
current tubes, and have years of experience in machining a huge range
of defects. From TWHs and FBHs, OD and ID grooves, milled flats, and OD and ID
thinning bands, to ID FBHs, ID contoured flats, 120°/180° wearscars,
tapered flaws, and tube-to-tube wear,

Heat Exchangers |
Nonferromagnetic
material Stainless steel, Cu/Ali |
X |
– ECT is the recommended choice for
its speed and accuracy.- IRIS can sometimes be used to confirm the sizing of
ID defects. |
|
Mildly ferromagnetic
material Duplex steel, SS439, Secure, Monel |
X |
– ECT is used only for thin tubes
(<1.6 mm) with saturation probes.- For thicker walls, it is better to use
RFT or MFL.- IRIS can sometimes be used to confirm the sizing of defects. |
|
|
Ferromagnetic material Carbon
steel, nickel. Typical defects are pitting and corrosion. |
X |
– RFT, MFL, and IRIS are good, and
most of the time complementary. |
|
|
Air Coolers |
Carbon steel tube with aluminum
fins Typical defects are ID pitting and OD wear close to the water box. |
X |
– RFT is not effective because the
fins disturb the remote field.- MFL is quick and sensitive but does not allow
sizing.- IRIS is often used to back up MFL but has difficulty with OD flaws. |
|
Boilers |
Carbon steel tube Typical
defects are pitting, wear, and cracking at the tube sheet. |
X |
– RFT is good for wear detection and
can easily pass the bend.- MFL is good only on straight boiler tubes without
swages.- IRIS is good for wear and pits but has no sensitivity in the bend. |
