RLA at NML Jamshedpur charts roadmap for industrial asset reliability

Panel discusses R&D-led solutions for plant components

Jamshedpur, April 10: The two-day national symposium on “Remaining Life Assessment of Engineering Components (RLA-2026)” concluded at the CSIR-National Metallurgical Laboratory, highlighting key technical insights and future strategies for extending the life of industrial assets.

The symposium brought together experts from industry, academia and research institutions, providing a platform to discuss the safety and reliability of critical infrastructure such as boilers, turbines, pipelines and refinery components. Participants emphasised the growing need for advanced diagnostic tools, predictive modelling and integrated assessment techniques to ensure cost-effective and safe operations.

Technical sessions covered areas including creep and stress rupture-based life assessment, corrosion management, risk-based inspection and advanced RLA methodologies. Delegates also visited state-of-the-art laboratory facilities at CSIR-NML.

During the valedictory session, speakers highlighted the importance of integrating Non-Destructive Evaluation (NDE), microstructural analysis and AI-driven data approaches for accurate life prediction of engineering components. They also stressed stronger collaboration between research institutions, academia and industry to address emerging engineering challenges.

A major highlight was a panel discussion on “Engineering Longevity: R&D Led Life Extension of Plant Components,” moderated by Dr J.K. Sahu. Experts including Sandip Ghosh Chowdhury, K.K. Sahu, A. Samanta of NTPC, Dr S.K. Nath of CPRI and K. Sateesh of MRPL shared insights.

A Samanta highlighted that RLA inspections for boilers are currently conducted every five to six years but stressed the need for more frequent checks and improved data quality. Dr S.K. Nath cautioned that while automation in testing has reduced time, quality must not be compromised. K. Sateesh pointed out inconsistencies in RLA reports due to poor data, stressing that accurate life extension depends on reliable information.

The panel also discussed challenges in material selection and hard coatings, noting issues such as weak bonding and early failure under abrasive conditions. To address skill gaps, experts proposed RLA certificate courses and industrial PhD programmes through AcSIR.

Director Sandip Ghosh Chowdhury appreciated the active participation of delegates and reaffirmed CSIR-NML’s commitment to research in structural integrity, while also thanking Prof R.N. Ghosh for his contributions.
