UNDERSTANDING
Types of ProbesECT
Eddy Current Testing has been developed
■
to inspect nonferrous materials inclu-ding austenitic stainless steel, brass, cop-per-nickel, titanium, copper-fi nned, and others.The Eddy Current technique is suitable for
■
the detection and sizing of metal discon-tinuities typically found in tubing applica-tions.It can detect and size defects like corro-
■
sion, erosion, wear, pitting, baffl e cuts, wall loss and cracks.Eddy current equipment is perfectly suited
■
for inspection of condenser tubes, feedwa-ter heaters and air conditioners.RFT
The Remote Field Testing technique is ■
used for the inspection of ferromagnetic tubing such as carbon steel and ferritic stainless steel.RFT is very sensitive to wall loss resulting
■
from corrosion, erosion, wear, pitting and baffl e cuts.The Remote Field equipment is perfectly
■
suited for inspection of heat exchangers, feedwater heaters, and boiler tubes.NFTThe Near Field Testing technique has
■
been developed specifi cally for the ins-pection of ferromagnetic fi n fanned tubes.The near fi eld is not affected by the pre-
■
sence of fi ns or affected by fi n geometry.NFT does not require an external balance
■
coil / probe
MFLMagnetic Flux Leakage is recommended
■
for the inspection of aluminium-fi nned carbon steel tubes because the magnetic fl ux is not affected by the presence of the fi ns.The technique detects irregularities such
■
as corrosion and steam erosion.MFL is also suitable for the detection of
■
circumferential cracks, a type of fl aw that is not detected by RFT and IRIS inspec-tion.
IRISThe Internal Rotary Inspection System is
■
an ultrasonic technique well suited for petrochemical and balance-of-plant tube inspection.It measure wall thickness, material loss
■
and defect orientation within the range of 0.5 in. to 3 in. ID.The equipment is designed for inspection
■
of tube and shell exchangers, air coolers and boilers tubes
A Detection level is set to a value that al-
■
lows the detection of the target, ID, and OD echoes.The fi rst echo is named T0 and the second
■
echo is named T1.If T0 is detected within the Target window, a
■
new rotation is done on the display.If T0 is outside the Target window, then the
■
following calculations are performed.
Two coils are excited with an AC current, producing a magnetic fi eld around them. The magnetic fi eld penetrates the tube material and
generates opposing AC currents in the material. These currents are called “eddy currents”.
Two strong, permanent magnets, coupled to a steel core, generate a magnetic fi eld that saturates the tube wall.
An absolute coil (ABS) is wound around the core to measure magnetic fi eld variation caused by general wall loss.
This fl ux leakage is detected by a differential coil (LEAD), located between the magnets.
A trailing coil (TRAIL), at the end of the probe, detects the residual magnetism from internal pits.
Any defects that change the eddy current fl ow will change the impedance of the coils in the probe.These changes in the impedance of the coils are measured and used to detect defects in the tube.
The basic probe is made with one exciter coil and two receiver coils. Two main fi elds are present, coupling the energy between the exciter and the receivers:The direct fi eld is centered around the exciter coil and is rapidly attenuated relative to the distance down the tube. The indirect fi eld is diffused outward through the tube wall, propagates along the tube axis, and is then rediffused back through the tube wall.
The zone in which the indirect fi eld is dominant is called the remote fi eld zone. This zone is present at a distance greater than two tube diameters.

Receiver effectThe fi rst receiver produces a signal when it moves past
■
the defect, and it is followed shortly after by a similar signal from the second receiver coil.The subtraction of both receiver signals generates the
■
“S” shaped differential signal.
Exciter effectThe exciter coil moves past the defect, affecting the fi eld
■
sensed by the receivers. Both receiver coils sense the exciter effect at the same
■
time and produce almost identical signals.If the defect is large, the exciter can have a small effect
■
on the differential signal because both receiver coils have a slightly different response.
Typical defect responseWhen the probe moves past a defect in the tube, the response is seen in terms of two effects:
Ultrasonic path in the tubeThe transducer produces an initial pulse.
■
The mirror may not be perfectly refl ective and produces a small
■
echo.Depending on the mirror orientation, the target pin echo is gene-
■
rated once every rotation.The internal diameter (ID) echo is generated with a strong ampli-
■
tude after the pin indication.Shortly after (because the ultrasonic velocity is higher in metal),
■
the outside diameter (OD) echo is generated with a much smal-ler amplitude.
Typical defect response
Location of the remote fi eld zone
Basic Concept of IRISA transducer located inside a turbine generates an ultrasonic pulse along the axis of the tube.
■
The ultrasound is refl ected on a 45º mirror and oriented toward the tube wall.
■
The ultrasound is partially refl ected by the tube ID, then transmitted through the wall, and fi nally
■
refl ected by the tube OD.The ultrasonic velocity of the tube material allows the wall thickness to be calculated by using the
■
time-of-fl ight difference between the OD and ID echoes.
Ultrasonic echo detection
OD defect detectionIf an outside diameter defect is located in the tube:The magnetic fl ux lines are not only distorted into the air outside the tube but also within the tube.
■
Since the tube wall is already saturated, the fl ux line distortions cannot be contained in the remai-
■
ning wall, and a fl ux leakage is created on the ID. The LEAD coil can detect this fl ux leakage because it is located between the magnets, in the mid-
■
dle of the magnetic circuit.The TRAIL coil, which is outside the magnetic circuit, cannot detect the defect because there is no
■
fl ux leakage inside the tube.
ID defect detectionIf there is an inside diameter defect, the magnetic fl ux lines are distorted in the tube when the ma-
■
gnetic circuit passes the defect.At this point, the LEAD coil can detect the fl ux leakage.
■
After the magnetic circuit passes the defect, some residual magnetism remains on the defect.
■
The TRAIL coil detects this residual magnetism and produces a signal output.

Skin depth effect
Basic Concept of Remote Field Testing
Basic Concept of Eddy Current Testing
Basic Concept of Magnetic Flux Leakage
Basic Concept of Near Field testing
The eddy current density in the material is not constant.The density is greatest at the surface (near the coil) and declines as it penetrates the material.This is called the skin depth effect.The “standard depth of penetration” is the depth where the eddy current density is 37% of its surface value.This standard depth of penetration is affected by:Frequency ■

The technology relies on a simple driver-pickup eddy current probe without the
requirement of an external referenced coil. It is design to provide very simple signals to
analyse. The probe measures the lift-off or fi ll factor and convert it as amplitude-based
signals. The penetration capability, which is limited to the inside surface, makes the probe
insensitive to fi n geometry on the outside of the tubes. In order to support the growing nDt community, olympus has pub-lished the “understanding tube Inspection technology” poster. this poster has been designed by field experts to present tube inspection technologies in a concise and clearly illustrated manner. this poster will become a valuable resource for those who are responding to the large demand for tube inspection solutions.

Tube Inspectionno single inspection technique is adequate for all types of materials and a single-technology system is only used for a narrow range of applications. the eddy current (ec) technique is commonly used to inspect nonferromagnetic materials. Remote field testing (RFt) and magnetic flux leakage (MFL) techniques are used for the inspection of ferritic materials and carbon steel tubes. the internal rotary inspec-tion system (IRIs) ultrasound technique is used for tube profilometry and corrosion mapping, and is a reliable validation technique for eddy current, remote field, and magnetic flux leakage inspections of any material.

Eddy Current Applicationseddy current is a noncontact method for the inspection of nonferromagnetic tubing. In this technique, the probe, which is excited with an alternating current, induces eddy currents in the part under inspection. Any discontinuities or material property variations that change the eddy current flow in the part are detected by the probe as a potential defect. this technique is suitable for the detection and sizing of metal discontinuities such as corrosion, erosion, wear, pitting, baffle cuts, wall loss, and cracks for nonferrous materials including auste-nitic stainless steel such as ss304/ss316, brass, copper-nickel, titanium, copper-finned, Monel®, and others.
For tube inspections, multifrequency eddy currents can locate and size defects under support plates and at the tubesheet. olympus eddy current equipment is perfectly suited for the inspection of condensers, feedwater heaters, air conditioners, and surfaces.
two coils are excited • with an electrical current, producing a magnetic field around them. the magnetic fields penetrate the tube material and generate opposing alternating currents in the material. these currents are called eddy currents.Any defects that change the eddy current flow also change the impedance of the coils in the probe.•these changes in the impedance of the coils are measured and used to detect defects in the tube.•
Probe responseAll tex series eddy current probes have a set of circumferential coils that can be operated simultaneously in absolute and differential bridge mode.
Differential response Absolute response
Connector and compatibilityAll tex series eddy current probes have the widely used 4-pin Amphenol connector. For a 6-pin Jaeger connector, add the letter J at the end of the probe or cable part number.
All tex series eddy current probes are compatible with most impedance bridge eddy current instruments. they are also compatible with the tc4700, tc5700, and Multiscan Ms 5800™.

If your tube dimension does not appear in the above chart, you can use the following formulas. be sure to round the probe diameter to the lowest 0.2 mm multiple.
note: this formula gives good results for tubes of a diameter near 1 in. (25.4 mm). For diameters greater than 2 in. (50.8 mm), it should not be used.
DIAM= 9.5 x ID (mm)Where: DIAM is the probe diameter x 10 mm
ID is the tube internal diameter
the tube oD is 24 mm, the wall thickness is 2.11 mm. Hence, the tube ID is 21.18 mm (25.4– 2.11– 2.11 = 21.18 mm).
the right probe DIAM would now be 201.21 (21.18 x 9.5 = 201.21). since the DIAM value is rounded to the lowest full value, the DIAM value is therefore 200 (20.0 mm).

the prefix “L” stands for “low-frequency” and represents the central frequency in Hz x 10. therefore, “L50” = 500 Hz.
the central frequency, in kHz, should be the closest as possible to the “F90” frequency required by a given tube material and wall thick-ness. the “F90” frequency is considered the “best” operating frequency as it provides a good phase lag between defects while keeping a good signal amplitude. At “F90,” there is approximately a 90° phase lag between a shallow internal defect (ID groove 10 %) and a shal-low external defect (oD groove 20 %). based on the tube parameters, the “F90” or central frequency is given by the equation below:

the distance between pickup and driver coils is 2.5 to 3 times the tube oD.
remote Field ApplicationsRemote field testing (RFt) probes are being used to successfully inspect ferromagnetic tubing such as carbon steel or ferritic stainless steel. they are very sensitive for detecting and measuring volumetric defects resulting from erosion, corrosion, wear, and baffle cuts. sensitivity to pitting has been further improved with the new design of the remote field probe.
the remote field probe is a low-frequency variant of the driver-pickup eddy current probe, characterized by a driver-pickup distance of at least 2.5 to 3 times the tube oD. this distance is necessary and critical in order to have the pickup coils sense the “remote” magnetic field rather than the “direct” field.
olympus remote field probes and equipment are used successfully around the globe to inspect heat exchangers, feedwater heaters, and boiler tubes. RFt is a through-wall transmission technique. the basic probe is made of one driver coil and two pickup coils. two magnetic fields are present: the direct field, in the vicinity of the driver coil, is rapidly attenuated with distance while the indirect field is diffused outward through the tube wall. the near field then propagates along the tube axis and is then rediffused back through the tube wall.
the zone where the indirect field is dominant is called the remote field. this zone is present at a distance greater than 2 tube diameters.
All remote field probes have their pickup coils set at 2.5 to 3 times the tube oD to ensure that only the indirect field is picked up. All olympus RFt probes have a set of circumferential pickup coils that can be operated simultaneously in absolute and differential mode.
ProBE rEsPonsEAll tRx series probes have a set of circumferential receiver coils that can be operated simultaneously in absolute and differential mode.

Wear scars, erosion, and wall loss are detected on both sides of the support plates by the Abs channel.
small defects such as individual pits are not detected by the DIFF channel on the near side of support, as a result of subtracting the same variations from the driver effect.

Dual-driver probes can detect wear pits on both sides of the sup-port plate, as there is always one driver to supply energy to the pickup coils.
duAl PICKuP (TrT sErIEs) used when defects are expected at the tubesheets •4 channels: Lead set (Abs/DIFF) and trail set (Abs/DIFF) •combines advantages of both single- and dual-driver models •Data analysis is longer and requires experienced users.•
the dual pickup acts as two single-driver probes in one probe casing, thus combining the excellent wall-loss response of the Abs channel plus the capability of the dual-driver model to detect pits on each side of the support plate. this makes the dual-pickup model ideal for inspecting at both tubesheets.
these probes require experienced operators as there are four channels to analyze, plus a delay between the lead and trail chan-nel sets.

Differential response Absolute response (remote field)
All tRx probes use a 19-pin Itt cannon® connector compatible with tc4700, tc5700, and Multiscan Ms 5800™.
the near field testing (nFt) technology is intended specifically for fin-fan carbon steel tubing inspection, without the requirement for externally referenced coils. this new technology relies on a simple driver-pickup eddy current probe designed to provide very simple signals for analysis. As the near field probes operate within the frequency range of standard remote field testing (RFt) technology, these probes are manufactured with the standard Multiscan Ms 5800 Itt cannon® 19-pin connector.
nFt probes are specifically designed to detect internal corrosion, erosion, or pitting on the inside of carbon steel tubing. these probes actually measure the lift-off or “fill factor” and convert it to amplitude-based signals (no phase analysis). As the penetration capability is limited to the inside surface, the nFt probes are made insensitive to fin geometry on the outside of the tubes.

If your tube dimension does not appear in the above chart, you can use the following equations. be sure to round the probe diameter to the lowest full value.
note: this equation gives good results for tubes with a diameter of near 1 in. (25.4 mm). For diameters greater than 2 in. (50.8 mm), it should not be used.
DIAM= 9 x ID (mm)Where: DIAM is the probe diameter x 10 mm
ID is the tube internal diameter
ExAmPlEthe tube oD is 24 mm, the wall thickness is 1.8 mm. Hence the tube ID is 20.4 mm (24 – 1.8 – 1.8 = 20.4 mm).
the right probe DIAM would now be 183.6 (20.4 x 9 = 183.6). since the DIAM value is rounded to the lowest full value, the DIAM value is therefore 180 (18.0 mm).

magnetic Flux leakage Applications
Magnetic flux leakage technique (MFL) is based on the magnetization of the material being inspected. the magnetization is provided by a strong magnet located inside the probe. As the probe encounters a wall reduction or a sharp discontinuity, the flux distribution varies around that area and is detected either with a Hall-effect transducer or with an inductive pickup coil.
MFL measures the magnetization of the tube to detect irregularities such as corrosion and steam erosion. MFL is recommended for the inspection of aluminum-finned carbon steel tubes because the magnetic flux is not affected by the presence of fins.
the MFL technique is also suitable for the detection of circumferential cracks, a type of flaw that is not detected by RFt or IRIs inspec-tions. For better results, the tFb series probes should be used along with the tF-ADp-001 adaptor.
ProBE rEsPonsEthe tFb series magnetic flux leakage probes have a set of circumferential receiver coils that can be operated simultaneously in absolute and differential mode. they also have a trailing coil that picks up the remaining magnetism present on the inside wall of the tube.

ProBE CABlEprobe cable material is manufactured in nylon (n) only.
cable lengths are in meters: 20 m (65 ft) is the most common. Also available in 30 m (100 ft) length.* Smaller diameter probes have less sensitivity to external defects as the probe core section is much smaller than the tube section. However, the sensitivity to internal defects is still very high.

IrIs Applications
the internal rotary inspection system (IRIs) is an ultrasonic technique well suited for petrochemical and balance-of-plant (bop) tube inspections. this technique uses an ultrasonic beam to scan the internal surface of the tube in helicoidal patterns, ensuring that the full length of the tube is tested. olympus tube inspection systems monitor the front-wall and back-wall echoes in order to measure the tube wall thickness.
the internal rotary inspection system probe operates in pulse-echo mode to measure wall thickness, material loss, and defect orientation within the range of 0.5 in. to 3 in. ID. the IRIs probe consists of an ultrasonic transducer firing in the axial direction of the tube. A mirror mounted on a water-propelled turbine deflects the ultrasonic beam in order to obtain a normal incidence wave on the internal wall of the tube. because the mirror revolves about the axis, the entire circumference of the tube is examined. A complete IRIs probe includes the cable, a centering unit, a turbine, and a transducer.
this equipment was designed for optimum results on various applications such as tube and shell heat exchangers, air coolers, and boilers tubes.

IrIs probe componentsVarious components are necessary to “build” an IRIs probe. the components are interchangeable and must be chosen according to the tube dimensions. For help with the IRIS probe-component selection, see table 7 on page 38.
to build an IRIs probe, the following components are necessary:
turbine head (tuA)•ultrasound transducer (tub),•centering device (tuc)•probe cable (tuD).•
TuA –TurBInE hEAdsIRIs turbines are propelled by water pressure to make them rotate at approximately 40 turns/s. they include a 45° angled mirror that deflects the ultrasound beam towards the tube wall.

Reverse Probe Adaptors
olympus has developed a series of “reverse probe adaptors” to allow the use of the olympus remote and near field probes in com-petitors equipment. each competitive equipment manufacturer has its own connector, input configuration, driver voltage, etc. these differences have resulted in the development of one adaptor model per instrument and probe technology. Indeed, all remote and near field probes, including the new series tRs, tRX, tRt, and tRD can now be connected to instruments like the Zetec MIZ-28 or corestar oMnI-100 and oMnI-200 and without the need for a cumbersome “RFt amplifier” box.
the list below presents the current released reverse adaptors. please note that olympus would be more than happy to develop a cus-tom reverse adaptors for your equipment.
