Excellence Integrity Management

One of the most dangerous corrosion mechanisms in Oil & Gas is also one of the hardest to detect.

Because you can't see it.

A pipe may appear perfectly healthy on the outside while losing significant wall thickness beneath the insulation.

No visible leak.

No obvious warning.

No indication of the risk developing underneath.

This hidden threat is known as Corrosion Under Insulation (CUI).

Industry studies have shown that CUI accounts for a significant percentage of piping maintenance costs and integrity-related failures across operating facilities.

The most common mistake?

Waiting for visible signs before taking action.

By then, the damage is often already severe.

High-risk locations include:

• Pipe supports
• Insulation terminations
• Valves and flanges
• Vessel nozzles
• Dead legs
• Areas exposed to water ingress

The best integrity programs don't inspect everything.

They identify where CUI is most likely to occur and focus resources accordingly.

Question for integrity and inspection professionals:

Where have you found the most severe CUI damage?
A. Pipe Supports
B. Valves & Flanges
C. Vessel Nozzles
D. Dead Legs
E. Insulation Terminations

Comment your answer below.

We're covering CUI mechanisms, inspection techniques, assessment methods, and mitigation strategies during our upcoming 4-Day Live Online Training on Corrosion Under Insulation (22–25 June 2026).

A material can meet every specification...

And still fail in service.

Why?

Because material selection alone doesn't guarantee reliability.

Understanding how materials behave under corrosive environments is what prevents leaks, cracks, failures, and costly downtime.

That's where corrosion testing becomes critical.

The right test can help engineers:
- Select suitable materials for challenging environments
- Predict degradation before failures occur
- Improve asset integrity and operational reliability
- Meet industry standards and compliance requirements
- Reduce lifecycle and maintenance costs

In this carousel, we've highlighted 11 important corrosion tests used across Oil & Gas, Petrochemicals, Power Generation, Marine, and Manufacturing industries.

Including:
• Salt Spray Testing (ASTM B117)
• Immersion Testing (ASTM G31)
• Humidity Testing (ASTM D2247)
• Cyclic Corrosion Testing (CCT)
• Pitting & Crevice Corrosion Testing
• Galvanic Corrosion Testing
• Intergranular Corrosion Testing
• Stress Corrosion Cracking (SCC)
• Sulfide Stress Cracking (SSC)
• Hydrogen Induced Cracking (HIC)
• Corrosion Fatigue Testing

Every corrosion mechanism tells a story.

The challenge is knowing which test to use before the failure writes the ending.

Equipment failures rarely happen without warning.

The warning signs are usually there:

• Corrosion progressing unnoticed
• Damage mechanisms not properly identified
• PSV performance degradation
• CUI hidden beneath insulation
• Tank and pipeline integrity issues developing over time
• Maintenance strategies focused on repairs instead of prevention

The challenge isn't a lack of data.

It's having professionals who can recognize the risks early, understand the mechanisms involved, and make the right decisions before failures impact safety, reliability, and production.

That's why organizations across the Oil & Gas industry continue investing in workforce competency.

Strong technical knowledge in areas such as:
- API 571 Damage Mechanisms
- Risk-Based Inspection (RBI)
- Pressure Safety Valves (PSV)
- Storage Tank Integrity (API 653)
- Pipeline Integrity Management
- Corrosion Under Insulation (CUI)
- Heat Exchanger Inspection & Maintenance
- Rotating Equipment Reliability
- Welding Inspection & Repair
- QA/QC Systems

helps teams move from reactive maintenance to proactive asset management.

The most reliable facilities are not necessarily the ones with the newest equipment.

They are the ones with people who understand how equipment fails, how risks develop, and how integrity can be maintained throughout the asset lifecycle.

At Excellence Integrity Management (EIM), we support organizations through specialized corporate training programs focused on inspection, integrity, reliability, maintenance, corrosion management, and asset performance improvement.

Our programs are delivered by industry professionals and built around practical applications, real-world case studies, and operational challenges faced by today's Oil & Gas workforce.

If your organization is looking to strengthen technical competency and improve asset reliability, let's connect.

Which technical competency do you believe delivers the greatest impact on asset reliability: Inspection, Corrosion Management, RBI, Maintenance, or Process Safety?

Preparing for an API 653 interview requires more than memorizing code clauses.

Employers look for professionals who can apply inspection principles, evaluate tank integrity, understand corrosion mechanisms, assess repairs, and make sound engineering decisions based on API 653 requirements.

A strong foundation in key topics such as tank inspection planning, remaining life calculations, minimum thickness evaluation, settlement assessment, repair requirements, and fitness-for-service concepts can make a significant difference during technical interviews.

To help storage tank professionals strengthen their knowledge and confidence, we have compiled:

The Top 20 API 653 Interview Questions

This resource is designed to help engineers, inspectors, and integrity professionals review important concepts commonly discussed during API 653 interviews and technical assessments.

✔ Interview Focused
✔ API 653 Specific
✔ Practical & Relevant
✔ Covers Key Industry Concepts
✔ Code-Compliant Knowledge
✔ Ideal for Engineers & Inspectors

Whether you are preparing for a new opportunity, certification journey, or simply refreshing your knowledge, mastering these fundamentals can help you stand out as a storage tank professional.

Most rotating equipment failures don't happen suddenly.

Weeks or even months before a breakdown, the warning signs are already there:

• Increased vibration levels
• Rising bearing temperatures
• Seal leakage
• Excessive noise
• Misalignment issues
• Lubrication problems

The challenge is that these indicators are often overlooked until equipment reliability is affected and unplanned downtime occurs.

Successful maintenance teams focus on identifying root causes rather than repeatedly fixing symptoms. Understanding vibration patterns, alignment practices, failure modes, and preventive maintenance strategies can significantly improve equipment performance and asset life.

Whether you're working with pumps, compressors, turbines, fans, or blowers, strengthening your troubleshooting skills can help reduce failures, improve reliability, and lower maintenance costs.

If you're looking to develop practical expertise in rotating equipment maintenance and troubleshooting, our upcoming live online training covers:

Most incident investigations stop too early.

They identify what happened.

But they fail to uncover why it happened.

A worker slips.
A pipeline leaks.
A pump fails.
A near miss occurs.

The immediate cause is easy to find.

The root cause is often hidden beneath layers of human factors, procedures, equipment issues, management systems, and workplace conditions.

This is where the Fishbone Diagram (Ishikawa Diagram) becomes a powerful tool.

By systematically examining six key areas:

• Man (People & Human Factors)
• Machine (Equipment & Reliability)
• Method (Procedures & Work Practices)
• Material (Quality & Suitability)
• Environment (Workplace Conditions)
• Management (Leadership & Systems)

organizations can move beyond assumptions and identify the real drivers behind incidents.

Why does this matter?

Because effective corrective actions can only be implemented when the actual root cause is understood.

The benefits include:

✔ Stronger incident investigations
✔ Improved safety performance
✔ Better decision-making
✔ Reduced risk of recurrence
✔ Enhanced safety culture
✔ Continuous improvement across operations

The most expensive mistake in incident investigation is treating symptoms while ignoring the underlying causes.
