Description
Magnetic Flux Leakage Calibration Tube
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° wears cars, tapered flaws, and tube-to-tube wear,

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. |
