Description

Remote Field Testing Calibration Tube RFT

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,

Application	Description	RFT	Comments
Heat Exchangers
	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.
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.
Buried Pipes	Carbon steel or cast iron pipes Typical defects are pitting and general corrosion.	X	– RFT is the only effective technique because it does not require cleaning, and it can easily negotiate elbows. However, sensitivity to pitting is limited.
