Breaking the Cycle: Innovative Cladding Solution Extends Reactor Lifespan and Saves Millions
The Recurring Challenge: Frequent Shutdowns for Erosion Damage
A petrochemical plant in the Middle East faced a persistent problem since commissioning: the need to shut down their unit every two years to replace components damaged by erosion. This issue was considered an unavoidable part of operations, with no apparent solution in sight.
The Hidden Costs: Financial and Operational Impacts
The two-yearly shutdowns had significant repercussions:
- Risk of unexpected tube leakage due to erosion
- Production loss for 3-4 weeks during each shutdown, costing millions
- Safety concerns related to working inside the reactor with specific entry protocols
The Search for Alternatives: A History of Limited Options
Initially, the company’s only recourse was to replace damaged items during each shutdown. No viable alternatives seemed to exist, leaving them stuck in this costly cycle.
A Glimmer of Hope: IGS Cladding Technology
The company had been using IGS for erosion protection since 2007, but never within the reactor. In a breakthrough, IGS developed a specialized material for this application in collaboration with the process licensor. In 2019, the company applied this cladding to some materials and found it intact even after four years.

The Decision: Embracing a Proven Solution
The impressive durability of the cladding after four years in service convinced the company that they had found the perfect solution. Key benefits included:
- Avoiding production losses
- Extending the duration between turnarounds
- Implementation: Adapting to Uncertainty
The implementation process presented unique challenges:
- Scope of work was uncertain until 1-2 days before execution
- Challenging reactor entry protocols
To overcome these obstacles, the team continuously improvised their plan daily based on the customer’s inspection team observations and adjusted resource allocation accordingly.
The Outcome: A New Era of Operational Certainty
Over four months, the cladding was applied to different parts of the reactor, providing comprehensive erosion protection. This solution:
- Delayed the next shutdown
- Eliminated the risk of unplanned shutdowns due to erosion issues
- Provided certainty in operations
The biggest success of the project was the team’s ability to adapt to changing scope and requirements throughout the implementation.
Lessons Learned: Innovating Beyond Initial Limitations
This case study demonstrates that even when solutions aren’t available during a plant’s commissioning, unique solutions can be developed later to change legacy maintenance practices and improve reliability. Companies facing similar challenges should remain open to innovative approaches that can transform their operations and significantly reduce costs over time.
