Structure
There are about 16 Scientists/Engineers and over 40 technical staff members. All the Scientists and Engineers have been trained and certified in various NDT
techniques from abroad under the Regional Cooperation Agreement (RCA) which is sponsored by the UNDP and
IAEA.
The centre has following Divisions:-
 Ultrasonic Testing
Division
The Ultrasonic Testing Division
(UTD) is capable of carrying out:-
-
Testing for manufacturing and in-service defects according to various
international codes and standards.
-
Mechanized inspection of simple geometry test specimens like tubes of less than a meter length and plates of less than a meter long and 350 mm width.
-
Thickness measurements of components.
-
Documentation of results with microprocessor based equipment.
Radiographic testing
Division
The Radiographic Testing
Division(RTD) is capable of carrying out:-
-
Radiographic testing for manufacturing and in-service defects according to various international codes and standards.
-
Development of procedures for radiographic testing of different jobs according to international codes and standards.
-
Welder's qualification according to international codes and standards for different jobs.
-
Testing of welds in pressure
vessels,pipes, heat exchangers, chemical
reactors, cooling systems of nuclear research ractors and power reactors.
-
Testing of small thickness casting components for minute cracks.
The available equipment include X-ray machines, Co-60 and Ir-92 sources for the testing of materials.
Metallurgy and leak testing
Division
The Metallurgy and Leak Testing Division
(MLTD) is capable of carrying out the following test services:-
Hydrostatic testing to check the strength and
leakage welds and other joints of vessels, heat exchangers, components etc.
Calibration of pressure gauges with dead weight tester with test range from 2psi to 8000
psi.
Destructive testing including Tensile test, Compression Test, Shear test, Bend test, Flattening test, Impact test ( Charpy & Izod test) and hardness test for the qualification of materials, welding producures and welders, etc, according to the international codes and standards.
Helium leak testing for very minute leaks in vessels, heat exchangers and other critical components, etc.,
which may be so small as to be undetected by other mean.
Pneumatic pressure testing to check the leakage in welds and other joints of vessels, heat exchangers, etc., where hydrostatic testing is restricted by the application code.
Identification and analysis of alloys by XRF alloy analyzer and chemical colour tests by Koslow Kit for the identification and analysis of more than 400 different alloys without damaging the surface of the samples.
In-situ non-destructive metallographic examination of in-service components of power plants, refineries, fertilizers plants, drilling rigs etc.
The available components include one hand operated and one motor driven Hydraulic test pump (maximum test pressure 5000 psi),one Universal testing machine (capacity 50 tons) one Impact testing machine (capacity 165 J & 300 J) one
Portable Digital hardness tester model Equotip, one Rockwell hardness tester, four Helium leak detectors ( detection upto 10-9 atm cc/sec). Air compressor (maximum test pressure 1000
psi), one portable NDT XRF alloy analyzer, one chemical test kit and in-situ metallography equipment with all the necessary accessories.
Surface methods
Division
The Surface Methods Division
(SMD) consists of PT, MT and VT (Borescopic inspection) techniques. This division is capable of carrying out the following jobs:-
-
Inspection of pressure vessels, heat exchangers, pipelines, storage tanks, chemical reactors, etc., for checking the integrity of their welds in accordance with the international codes and standards.
-
To detect fatigue and creep cracks during the
over hauling of jet engines, chemical plants, nuclear power plants, oil refinery,
railroad and automotive industries.
Eddy Current Testing
Division
The Eddy Current Testing Division (ETD) is capable of doing the following
jobs:
-
Inspection of tubes
of aluminum, stainless steel, brass, copper, incomel, zirculloy, etc., to detect and identify
defects, viz internal, external, through wall, a dent, a corrosion
deposit, a crack etc.
-
Sorting of materials based on metallurgical differences.
-
Inspection of in-service components such as turbine
blades, holles in the tubes of aeroplane wheels, nuts
and studs of reactor pressure vessels for surface and
sub-surface cracks.
-
Detection of surface-open cracks in
metals with paint or coating with insulated materials.
-
In-service inspection such as of heat exchangers and
condenser tubes of magnetic and non-magnetic materials.
-
Coating and plating thickness measurement of conductive and non-conductive materials on conductive and non-conductive base materials.
-
R&D work on the fabrication of Eddy Current probes for various diameter tubes of different materials and alloys of non-magnetic and
ferro-magnetic behaviour.
Acoustic Emission and failure
analysis (AEFA) Division
Acoustic Emission non-destructive testing has the capability of monitoring defect growth in high stress regions of components in real-time and without any shutdown. Acoustic Emission monitoring of defect growth is particularly suitable for;-
Failure analysis of a structure based on Fracture Mechanics methodology is a requirement on in-service inspection codes starting with the detecting of crack initiation, goes along the crack
propagation and continues till final analysis of component failure. The activities of AEFAgroup are summarized below:-
