The performance of critical bolted joints remains fundamental to plant safety, uptime, and long-term asset integrity. As power generation systems continue to evolve, operators are under increasing pressure to improve flexibility, extend equipment life, and maintain reliability under more demanding operating conditions. Whether the source is wind, water, fossil fuels, or nuclear, power generation brings operating challenges such as extreme temperatures and severe vibrations.

Why bolted joint integrity matters

In many cases, bolted joint failures are not caused by a single component issue, but by a combination of factors such as insufficient preload, inconsistent tightening methods, vibration, dynamic loads, and installation variability. Even small deviations during assembly can have a significant impact on joint security and operational performance over time. Maintaining accurate preload and reducing variability during installation are key to achieving reliable joint performance throughout the service life of the equipment.

Engineering reliability in demanding power applications

Rather than focusing on individual products, the discussion will centre on the engineering principles that influence joint reliability, including load distribution, tightening strategy, and risk reduction in critical applications. The webinar reflects the Nord-Lock Group’s commitment to improving bolted joint safety and reliability through engineering expertise, application knowledge, and technologies designed to secure bolted connections in demanding environments.

What you will learn:
• Hydraulic, mechanical, and conventional tightening methods
• Preload accuracy and clamp load retention
• The impact of vibration and dynamic loads on bolted joints
• Human factors and installation variability
• Maintenance considerations and long-term joint performance
