2. Project Description
In more than last 59 years the inspection and maintenance technologies of Power
generation and production industry have been developed all around the world. To
detect the problem and avoid the failure of Power generation and Production plant
(like power, petrochemical, fertilizer, Pharmaceuticals, Cement Plant, Aviation,
Ship Building) is very important and essential to develop the Non Destructive Testing
(NDT) and Condition Monitoring (including Vibration Analysis, Oil Analysis, Ultrasonic
Analysis and Thermal Analysis). Most of power and process plants in Bangladesh are
very aged, maintenance cost come huge and irregular shut down they cannot produce
optimum power and production. By developed predictive maintenance concept you can
minimize plant maintenance cost reduce plant irregular shut down and it help increase
plant efficiency.
Object of the Project:
 Develop the NDT and Condition Monitoring facilities for Power Generation and
production Plant.
 Make more reliable to power plant Service.
 Save the plant from upcoming failure.
 Reduce the Lube Oil Cost by increasing the interval time of oil change.
 Detect the engine problems by Lube Oil Analysis.
 Avoid the accident caused by hidden crack/damage of critical power plant
equipment
 Reduce the maintenance cost by doing maintenance where and when required.
 Make the proper maintenance and inspection facility for new plant.
Predictive maintenance (PdM) techniques help determine the condition of in-service
equipment in order to predict when maintenance should be performed. This approach
offers cost savings over routine or time-based preventive maintenance, because tasks
are performed only when warranted.
The main value of Predicted Maintenance is to allow convenient scheduling of corrective
maintenance, and to prevent unexpected equipment failures. The key is "the right
information in the right time". By knowing which equipment needs maintenance,
maintenance work can be better planned (spare parts, people, etc.) and what would
have been "unplanned stops" are transformed to shorter and fewer "planned stops",
thus increasing plant availability. Other advantages include increased equipment
lifetime, increased plant safety, fewer accidents with negative impact on environment,
and optimized spare parts handling.

3. Non-Destructive Testing is a noninvasive technique for determining the integrity of a
material, component or structure. Because it allows inspection without interfering
with a product's final use, NDT provides an excellent balance between quality control
and cost-effectiveness.
Condition monitoring is the process of monitoring a parameter of condition in
machinery, such that a significant change is indicative of a developing failure. It is a
major component of Predictive Maintenance (PdM). The use of conditional
monitoring allows maintenance to be scheduled, or other actions to be taken to
avoid the consequences of failure, before the failure occurs.
Condition Monitoring Parameter:
1. Vibration Analysis
2. Oil Analysis
3. Thermal Analysis
4. Laser Alignment
5. Dynamic Balancing

4. NDT and CM for Power Generation
We provide nondestructive inspection products and solutions for key power
generation applications, including those for fossil, nuclear, renewable energy markets,
transmission and distribution. Our reliable, advanced technology inspection solutions
and support services enable power generation customers to help maximize
efficiency, minimize downtime and enhance productivity with unyielding integrity.
Primary and secondary piping: To prevent leakage and failures, piping is regularly
inspected for corrosion, weld defects and gas accumulation using ultrasonics, remote
visual inspection and direct radiography systems. These same technologies are also
used to inspect pipes, welds and vessel components to help ensure integrity.
Feed water heaters, condensers and heat exchangers Proper operation of these
crucial components is essential for efficient operation of a power plant. Each machine is
inspected internally and externally for fitness for service. Ourmenu-directed remote
visual inspection and eddy current systems can detect defects and cracks that cause
leaks.
Nuclear submarines
To help ensure maximum safety of a submarine crew, numerous nondestructive tests
are carried out to verify quality of
the vessel girth welds, steam generator system, primary and secondary piping and
reactor vessels. The submarine environment demands use of all nondestructive
technologies to help ensure safety.
Feed water heaters, condensers and heat exchangers Proper operation of these
crucial components is essential for efficient operation of a power plant. Each machine
is inspected internally and externally for
fitness for service. Ourmenu-directed remote visual inspection and eddy current
systems can detect defects and cracks that cause leaks.
Reactor vessel
High-pressure boilers and vessels are kept operating safely using remote visual
inspection. Regular inspection for cracks and defects help ensure safe operation
and help prevent loss of structural integrity of the vessel.
Nuclear fuel and fuel rods
Ultrasonics, eddy current and radiography are commonly used inthe manufacturing
environment to test rods for ovality to ensure the rods fit into a fuel cluster. A fuel
assembly that does not fit precisely as designed can cause long and unacceptable
delays in a plant maintenance outage.
Turbines and generators
Using our remote visual inspection, eddy current and ultrasonic systems, blades and
dovetails found in rotating machines, such as turbines and generators, are inspected
for cracks and defects to minimize downtime and possible injury.

5. Reactor vessel
High-pressure boilers and vessels are kept operating safely using remote visual
inspection. Regular inspection for cracks and defects help ensure safe operation
and help prevent loss of structural integrity of the vessel.
Transmissionand distribution
Remote visualinspection ofswitcheshelps ensure compliant and safe operation of
the substation. Digital Radiography allows for condition-based maintenance of
gas-insulated switches.
Image and data sharing
Rhythm software ties all inspected components of the plant into one data file and
helps plant operators plan maintenance rather than react to forced outages.
DICONDE compliant, this software platform is compatible with our digital radiography,
phased array ultrasound, remote visual inspection and eddy current technologies.
Rhythm
encompasses the image management tools that help ensure thorough inspection
results and rapid data sharing.
Manufacturing power plant components
The very low tolerance for manufacturing defects or foreign matter inclusions in
large forgings, such as turbine shafts or in controlling piping and vessel materials,
is mitigated by using nondestructive testing systems in the manufacturing facility.
Our radiography, film or digital solutions, coupled with ultrasonic, detects
volumetric defects. Our eddy current systems are used for near surface defect
detection.
Blade manufacturing for windenergy
Throughout the steps of the blade manufacturing process, ultrasonic technology is
used to test composite material for delaminations and defective layering to ensure
quality. The bonding of portions of the blade to one another and support structures is
also monitored using ultrasonics.
Transmissionand distribution
Remote visualinspection ofswitcheshelps ensure compliant and safe operation of
the substation. Digital Radiography allows for condition-based maintenance of
gas-insulated switches.
Wind Generation
Condition-based inspection of the gearbox in the nacelle
decreases the likelihood of catastrophic failure and enables
scheduling of repairs and preventative maintenance. Oureasy-
to-use remote visual inspection systems require no special
training, while producing more uniform inspection results.

Remote Visual Inspection (RVI) :
Remote means inaccessible, where you cannot reach by naked eye. Some tools will help
you look remote zoon where you desire to look without open or disassemble or destroy.
Remote Visual Inspection (RVI) is a Non-Destructive Testing (NDT) technique used to
detect and examine a variety of visible flaws; such as cracks, corrosion, contamination,
structural integrity, and other discontinuities. Remote visual inspections also often
provide supplemental information for other NDT methods. Remote Visual Inspection is
by far the most common and relatively simple NDT technique. Visual Testing (VT) is
usually the first choice of any inspection as it offers an immediate and less costly
approach as compared to other NDT methods.

Dye penetrant inspection (DPI),

10. Dye penetrant inspection (DPI), also called liquid penetrant inspection (LPI) or
penetrant testing (PT), is a widely applied and low-cost inspection method used to
locate surface-breaking defects in all non-porous materials (metals, plastics, or
ceramics). The penetrant may be applied to all non-ferrous materials and ferrous
materials, although for ferrous components magnetic-particle inspection is often used
instead for its subsurface detection capability.
Materials that are commonly inspected using LPI include the following:
- Metals (aluminum, copper, steel, titanium, etc.)
- Glass
- Many ceramic materials
- Rubber
- Plastics
Liquid penetrant inspection can only be used to inspect for
flaws that break the surface of the sample. Some of these flaws are
listed below:
- Casting defect
- Forging defect
- Welding surface defects
- Hairline cracks
- Surface porosity
- Leaks in new products
- Fatigue cracks on in-service components
- Quench cracks

13. Ultrasonic Flaw Detection ( Conventional):
In ultrasonic testing, high frequency sound waves created by a vibrated crystal in probe
are transmitted into a material to detect imperfections or to locate changes in material
properties. The most commonly used ultrasonic testing technique is pulse echo where-
by sound is introduced into a test object and reflections (echoes) from internal
imperfections or the part's geometrical surfaces are returned to a receiver. This method
is very sensitive to detect crack type defects but requires extensive training for operator
to interpret the result.
Applications:
Most weld discontinuities including
- Cracks,
- Slag,
- Lack of fusion,
- Lack of bond,
- Accurate thickness measurement possible
- To measure intergranular corrosion quantitatively
Advantages :
Most sensitive to planar type defects
Test results known immediately
High penetration capability
Requires access from only one surface
06.
Advanced Ultrasonic Phased Arrays:
Phased array Ultrasonics (PA) is an advanced method of ultrasonic testing that has
applications in medical imaging and industrial nondestructive testing. Common
applications are to noninvasively examine the heart or to find flaws in manufactured
materials such as welds. Ultrasonic test instruments have been used in industrial
applications for more than sixty years. Since the 1940s, Conventional UT used single
element transducer Phased array system use multi element transducer. So PA scanning
speed is much higher and accurate than conventional.
Phased array is widely used in several industrial sectors, such as construction or power
generation. This method is an advanced NDT method that is used to detect component
failures i.e. cracks or flaws and thereby determine component quality. Phased array can
be used for the following industrial purposes:
 Inspection of Welds
 Thickness measurements
 Corrosion inspection
 Flaw detection
 Detect hidden cracks,
 Voids,
 Porosity,

14.  Other internal discontinuities in metals,
 Composites, plastics, and ceramics, as well as to measure thickness and

Radiography Testing Products
Radiography is the most commonly known non-destructive test method. Radiography
can be used to obtain permanent image of surface and sub-surface (embedded)
discontinuities. The same discontinuities can be radiographed again after a period of
service life and the radiographs can be compared to measure the change in the size and
shape of the discontinuity. There are numerous applications of radiography in
engineering applications.
Some of the common uses are detection of surface and subsurface features of interest in
welded parts, castings, forgings, wall thickness measurement, corrosion mapping,
detection of blockages inside sealed equipment, detection of reinforcing material in
concrete slabs, measuring bulk density of materials measuring porosity in concrete etc.
The conventional film radiography is the most sensitive test method. On the contrary
digital or computed radiography have certain advantages over conventional film
radiography.

08. Eddy Current:
Eddy-current test uses electromagnetic induction to detect flaws in conductive
materials. The eddy current test set-up consists of a circular coil which is placed on the
test surface. The alternating current in the coil generates changing magnetic field which
interacts with the conductive test surface and generates eddy current. The flow of eddy
current can be disrupted due to change in resistivity or conductivity, magnetic
permeability, any physical discontinuities. The change in eddy current flow and a
corresponding change in the phase and amplitude is measured against known values.
Eddy current test method can detect very small cracks in or near the surface of the
material, the surfaces need minimum preparation. The biggest advantage of the eddy
current test method is that is can be employed to determine surface flaws on painted or
coated surface. Eddy current flaw detection is commonly used in the aerospace industry,
crane industry, concrete pumping industry and other general industries where the
protective surface coating cannot be removed.
The crane industry and crane owners benefits most from the application of eddy current
test method to detect surface flaws underneath the protective coating (paint ). The
exorbitant cost of paint removal and repainting is eliminated by applying eddy current
flaw detection method as compared to magnetic particle test. It is also useful for making
electrical conductivity and coating thickness measurements. Eddy current test is
commonly employed for rapid thickness testing of coatings - conductive and non-
conductive.
The principle of eddy current test which measures the change in resistivity in the

16. conductive material makes it useful in wide range of applications such as conductivity
measurement, sorting of material, assessment of heat treatment condition, sorting of
materials on the basis of hardness and strength, thickness measurement of thin
components.

and sub-surface of metals such as tubes. A number of main areas have been identified
where cracking occurs are Eddy current inspections form a vital part of checking
power plant for the cracks and faults that can lead to serious accidents. As many of
the cracks appearing in power plant are fatigue induced and thus surface- breaking,
it is important to employ eddy current inspection methods in order to detect them.

17. Hardness Tester:
Hardness Testing is a widely used method for determining hardness of materials using
test methods such as Vickers, Brinell, Knoop, Rockwell, Shore and IRHD. Portable
hardness testers come in a variety of types with the ability to test most metals, alloys
and plastics ranging from soft polymers, steel, cast steel, alloy tool steel, stainless steel,
grey cast iron, spheroid iron, cast aluminum, brass, bronze and wrought copper rubbers
to engineering alloys designed for use in the most arduous conditions or most severe
operating environments.
Model:…………testers are very precise, easy to operate and are used to identify and
classify parts in stock, measure in areas with limited access, control large and/or heavy
parts on-site and to conduct tests during production.
11.
XRF X-RAY FLUORESCENCE/PMI (POSITIVE MATERIALS IDENTIFIER):
XRF means X-ray fluorescence. XRF is the emission of characteristic "secondary" (or
fluorescent) X-ray from a material that has been excited by bombarding with high-
energy X-rays.
Material tracking and confirmation is critical to the production and maintenance of
petrochemical processing and power generation facilities. X-ray diffraction (XRD) and X-
ray fluorescence (XRF) analyzers are used for incoming material verification, safety
assurance, PMI, and maintenance.

 In-service inspection (no production shutdown).
 Inspection lengths range up to 182 meters (600 feet) for single point.

24. 18.
When moving from reactive maintenance to predictive maintenance, it is crucial that
breakdowns are really understood. One of the basic analysis techniques is to use high-speed
cameras in order to characterize events which happen too fast to see, e.g., during
production. Similar to in science, with a pre- or post-triggering capability the camera can
simply record continuously as the mechanic waits for the breakdown to happen, following
which a trigger signal (internal or external) will stop the recording and allow the investigator
to save a given time interval prior to the trigger (determined by frame rate, image size, and
memory capacity during continuous recording). Some software allows viewing the issues in
real time, by displaying only a subset of recorded frames, minimizing file size and watch time
issues by eliminating useless frames before or after the sequence of interest.
