FAILURE INVESTIGATION View
An innovative approach is adopted in investigating the failures. Most of the investigations are on different metals/alloys that are in Mechanical, Chemical, Petrochemical, Paper-pulp, Fertilizer and Power generation industries. The analytical
approach is adopted to corelate History of Failure & Operation, Visual Examination, Mechanical & Design Consideration, Fractographic Analysis by SEM, Chemical Analysis, EDAX Analysis, Metallurgical Micro- structure Study, Micro-hardness &
Hardness Test.
Based on investigative results, the cause of failure is identified & recommendations are made to prevent failure.
The report is prepared with comments and recommendations.
Have a look at certain case studies, which highlight the approach adopted in the detailed failure investigation in order to arrive at precise conclusions.

REMAINING LIFE ASSESSMENT (RLA)
A pragmatic approach is adopted in handling the cases of remaining life assessment.
Efforts are put in to collect as much data as possible on the component / equipment
history. Often brain storming sessions are conducted with the concerned people
using the equipments. The outside exports who are familiar with the operational
details. To collect opinions and ideas, which are evaluated vis-à-vis the testing and
studies conducted at a latter stage.
The salient features involved are:
- Understanding the actual degradation mechanism
- Visual examination
- NDT involving In-situ Metallo-graphy, Ultrasonic Testing,
Magnetic Particle Inspection, DP Test, Ferrite Measurement.

IN-SITU METALLOGRAPHY
Performed as an NDT service, In-Situ Metallography from TCR determines in-service degradation of critical components of process plants operating under high temperature, high pressure or corrosive atmosphere. TCR’s Metallurgists have strong experience in the interpretation of microstructures. TCR has more then 10,000 replica microstructure interpretations that have been logged and captured to our databases. These databases contain extensive information from various plants that have been captured over the course of us performing this service. The databases also include rare collections of varying microstructure damage levels for various industries such as power, oil and gas, petrochemical, fertilizers, and other process industries. more...

ADVANCED MATERIAL TESTING LABORATORY
The core services TCR provides include Mechanical Testing, Chemical Analysis,
Positive Material identification (PMI), Non Destructive Testing, Metallo- graphy,
Corrosion Testing, Failure Analysis, Raw Material Inspection, Metallurgical Product
evaluation, Engineering Research and Consultancy.
TCR tests ferrous and non-ferrous metal, casting & forging, sheet metal, bar, pipe,
stainless steel, nuts, bolts, engineering goods, non-metallic materials such as
polymer, ceramic, glass, machined parts, and machine tool components.
TCR has in-house Mechanical Testing Facility for hardness, tensile, compression, impact, weldability, fatigue and bend properties. We are performing tests as per ASTM, BS, IS, DIN, or client specified standards.
