TCR Media November 28, 2025In today’s industrial environment, reliability and safety are key to successful operations. Whether it’s a boiler tube failure, a shaft malfunction, or an unexpected equipment breakdown, every failure has a story behind it. Understanding that story is essential — and that’s where Failure and Root Cause Analysis plays a vital role.
At TCR Advanced Engineering Pvt. Ltd., we specialize in comprehensive Failure and Root Cause Analysis for a wide range of industrial components and systems. Our expertise lies in identifying not only what failed, but why it failed. By uncovering the underlying causes of breakdowns, we help industries prevent recurring issues, enhance system reliability, and improve operational efficiency.
Failure and Root Cause Analysis (RCA) is more than a problem-solving process; it’s a scientific and engineering-based investigation that digs deep into the mechanisms behind a failure. Whether it’s Boilers Tube Failure Investigations, Shaft Failure Investigations, or material fatigue studies, TCR Advanced Engineering Pvt. Ltd. delivers accurate, evidence-based insights that drive corrective and preventive actions.
What is Failure and Root Cause Analysis?
Failure and Root Cause Analysis is a structured, step-by-step approach to identifying the origin of an equipment or component failure. It goes beyond visible damage to find the real cause — be it design defects, material degradation, corrosion, or human error.
For example, if a boiler tube failure occurs, simply replacing the tube is not enough. The real question is: Why did it fail? Was it corrosion, overheating, or operational error? Through detailed Boiler Tube Failure Investigation, TCR Advanced Engineering Pvt. Ltd. identifies the exact cause and provides effective recommendations to prevent recurrence.
The process includes:
- Data Collection: Gathering operating conditions, design information, and maintenance records.
- Visual and Microscopic Examination: Observing cracks, wear, and deformation patterns.
- Material and Chemical Testing: Using metallography, hardness tests, and corrosion analysis.
- Root Cause Identification: Applying techniques like the Fishbone Diagram or 5-Whys Method.
- Corrective Actions: Suggesting operational, material, or design improvements.
Our specialized laboratories and experienced metallurgists ensure that every Failure Investigation conducted by TCR Advanced Engineering Pvt. Ltd. is accurate, detailed, and actionable.
Why Failure and Root Cause Analysis is Essential
In any industrial setup, even minor failures can lead to significant production losses, safety risks, and maintenance costs. A proper Failure and Root Cause Analysis not only identifies the issue but ensures it doesn’t repeat.
At TCR Advanced Engineering Pvt. Ltd., we believe that understanding a failure is the first step to achieving operational excellence. Our Failure Investigation Reports provide clients with insights that improve equipment reliability, reduce downtime, and enhance safety.

Common Causes of Industrial Failures
During Failure Investigations, our engineers at TCR Advanced Engineering Pvt. Ltd. often identify a combination of causes that contribute to the breakdown. Common factors include:
- Material Defects: Improper alloy composition or inclusions in the material.
- Corrosion: Chemical reactions that weaken metal integrity.
- Fatigue: Repeated cyclic stress leading to microcrack formation.
- Overheating: Caused by poor cooling, scaling, or operational imbalance.
- Human Error: Mistakes during operation or maintenance procedures.
- Design Issues: Inadequate stress allowance or improper load distribution.
By recognizing these factors, Failure and Root Cause Analysis enables industries to take preventive actions before a problem becomes critical.
Boiler Tube Failure Investigation
Boilers are critical to industrial operations, and any tube failure can result in costly shutdowns. Through Boiler Tube Failure Investigation, TCR Advanced Engineering Pvt. Ltd. helps clients uncover the exact cause of failure and develop preventive maintenance strategies.
Common Causes Identified:
- Corrosion and Erosion: Due to chemical reactions or steam impingement.
- Overheating: From poor heat transfer caused by scale formation or blockage.
- Fatigue Cracking: Resulting from temperature cycling and stress fluctuations.
- Manufacturing Defects: Improper welding or inconsistent wall thickness.
Our team performs detailed Failure Analysis through metallurgical studies, non-destructive testing, and microscopic evaluation. A comprehensive Failure Investigation Report outlines the mode of failure, contributing factors, and recommendations for process or material improvements.
At TCR Advanced Engineering Pvt. Ltd., our Boilers Tube Failure Investigations not only solve immediate problems but also enhance long-term boiler performance and safety.
Shaft Failure Investigation
Rotating shafts in turbines, pumps, or compressors face high mechanical stress and fatigue loads. When a failure occurs, it often disrupts entire production lines.
TCR Advanced Engineering Pvt. Ltd. conducts detailed Shaft Failure Investigations to determine whether the cause is operational, material-based, or design-related. Common causes include:
- Fatigue Cracks due to cyclic loading.
- Misalignment causing uneven stress distribution.
- Overload or Sudden Shock Loads.
- Improper Heat Treatment affecting hardness and ductility.
Using advanced analytical techniques such as SEM (Scanning Electron Microscopy), fractography, and metallurgical evaluation, our engineers provide clear insights. The resulting Failure Investigation Report includes practical recommendations like redesigning shaft geometry, improving lubrication, or modifying operation speed.
Our focus is not just on identifying failure — but preventing it from happening again.
