Introduction
Every process plant—be it a refinery, chemical unit, or power facility—depends on critical components such as reactors, pipelines, and heat exchangers. Over time, these components are exposed to high temperature, pressure, and corrosion, all of which gradually weaken their integrity.
When a component nears the end of its life cycle, undetected degradation can lead to catastrophic failures or unplanned shutdowns. That’s where Remaining Life Assessment (RLA) by TCR Advanced Engineering comes in. Through advanced testing, metallurgical evaluation, and data analysis, RLA determines how long your equipment can safely and efficiently continue to operate.
What Is Remaining Life Assessment?
Remaining Life Assessment (RLA) is a scientific process that estimates the residual life of components after long-term service. Instead of relying on arbitrary replacement schedules, RLA uses actual condition-based data to make informed maintenance decisions.
By evaluating damage such as creep, corrosion, fatigue, and oxidation, TCR Advanced helps industries answer a critical question: Can this component safely continue to run, and for how long?
Why RLA Matters for Process Plants
Process industries operate round the clock, and reliability directly impacts productivity and safety. RLA ensures that every critical part of your plant—pressure vessels, piping systems, exchangers, and reactors—is fit for continued service.
Key benefits include:
Estimating asset life and delaying unnecessary replacements
Reducing unplanned downtime and operational risks
Improving maintenance efficiency through data-based scheduling
Complying with global safety standards like API 579 and ASME codes
Optimizing capital expenditure by focusing on components that truly need attention
TCR Advanced’s RLA Methodology
With more than two decades of experience and over 6,000 investigations completed globally, TCR Advanced is a trusted partner for RLA of process plant equipment.
Our systematic approach includes:
Data Review & History Analysis: Studying design specifications, service history, and past maintenance records.
Visual & NDT Inspection: Employing ultrasonic, eddy current, and thickness gauging to identify cracks, thinning, or surface defects.
In-Situ Metallography: Examining microstructures directly on-site to assess creep damage, grain coarsening, and metallurgical aging.
Mechanical & Chemical Testing: Evaluating hardness, and composition to estimate the remaining strength and verify material integrity.
Life Prediction & Reporting: Calculating remaining life using temperature-stress data and providing actionable recommendations for continued operation, repair, or replacement.
Each RLA study concludes with a comprehensive report outlining the current health of your equipment and recommandations for continued safe, efficient use.
Case Example
A chemical processing plant commissioned TCR Advanced to assess the condition of aged heat exchangers that had been in service for over 18 years. Using in-situ metallography and ultrasonic testing, the team identified minor surface creep and corrosion but no critical defects.
As a result, TCR recommended continued operation with a revised inspection schedule—saving the client significant capital expenditure while maintaining safety standards.
