Inspections:
Special Inspection I:
Heat Exchanger Tubing Inspection Tech.
In the inspection of heat exchanger tubing
by eddy current testing, flaw size and its
location are evaluated through the phase and
magnitude of signal on impedance plane.
Thickness Gager Using EMAT(EM-2000)
The thickness gager using electro-magnetic
acoustic transducer (EMAT) doesnt liquid
couplant as well as removal of oxide
coating.
Pipe Socket Weld Point Inspection Tech.
The inspection of pipe socket weld is
difficult and magnetic particle testing and
liquid penetrant testing are usually done to
inspect the surface of pipe socket.
Ultrasonic Inpection Tech. to Test
Austenitic Weld
The austentic weld zone has anisotropy and
coarse grain size in the microstructure. The
coarse grain structure combined with the
marked anisotropy is the reason for the
strong scattering which for a long time has
made ultrasonic testing of such structures
using transverse waves impossible.
Tubin Rotor / Blade Inspection Tech.
Due to the complicated shape of turbin
rotor/blade, it needs high inspection
technology. We have well established
ultrasonic test procedure as well as special
engineers and have been achieved high
reliability in this area.
Intelligent Pigging for Inspection of
Pipeline
In order to meet the high requirements
regarding availability, economic use and
pipeline safety in an efficient manner,
intelligent pigs are increasingly being used
for preventive pipeline inspections.
Special Inspection II:
TOFD (Time of Flight Diffraction)
- More complete and accurate
characterization and sizing of defects.
- Weld Inspection using Motorized Scanner,
Handheld Scanner.
- Corrosion diagnostic (reject/accept) based
an automated image analysis.
Crawler System to Inspect Pipeline Inner
Side
- 360 rotation of mirror.
- Scan distance and location can be known by
encoder.
- Inspection of pipelines larger than 100mm
ID.
Radiographic Test Using a Radioisotope
Se-75
When the radioisotope, SE-75 is substituted
for Ir-192 as a radiation source in
radiographic testing, it is found that the
exposure tine increases up to 1.0 1.6
times and the exposure dose-rate decreases
to 0.44 0.60 times with increment of
thickness of carbon steel.
Tangential and Density Profile Radiography
Compared to tangential radiography, it needs
relatively short exposure time to obtain the
proper density condition but can inspect the
more wide area of pipe in a shooting, so it
can help to reduce the irradiation to the RT
workers and to enhance productivity of
radiograohic testing for thickness
measurement.
Advanced Inspection:
Eddy Current Signal Analysis Tech.
- Seamless or welded tube made of austenite
stainless steel can take magnetic phases by
fabrication processes.
- High speed inspection, high quality
analysis will be provided by signal pattern
analysis technology.
Phased Array Ultrasonic Inspection System
(PAULI)
- Real-time display of inspection result.
- Easy and precise detection of flaw
location.
- Detection sensitivity: 0.3mm, Special
resolution: 0.2mm
Replica to Assess Material Degradation
The in-situ evaluation of micro-structural
deterioration in the materials subjected to
severe environments of high pressure and
temperature is one of the most important
technologies for the remaining life
assessment.
Advanced Indentation System (AIS 2000)
- Can be used in field, laboratory
condition.
- Measurement of yield strength
work-hardening exponent, hardness.
- In-situ measurement of mechanical
properties.
Safety Diagnosis Using FFS (Fitness for
Service) Program
- Based on API 579 Fitness for Service
(2000)
- Based on BS PD6493 Guidance on methods
for assessing the acceptability of flows in
fusion welded structure (1997)
- Engineering analysis about fitness for
service of pressure vessels including piping
and tanks.
