Bolted Assemblies: issues and new challenges

« Screwed assemblies: issues and new challenges »


In bolted assemblies, control of the design and implementation are key issues for the reliability of the connections.

Optimization is a challenge to achieve economical solutions, particularly in terms of weight and size.

We propose to discover these issues and challenges during this presentation.





Topics covered during the presentation:

Features presented from case studies:

  • Context
  • Ageing of equipment
  • Proof of fatigue strength of steel structures in Europe: Eurocodes
  • Crane design, residual life of cranes and related Rules and Standards
  • Pressure vessels and boilers
  • Cetim’s general methodology for evaluation of Residual Life
  • Some industrial examples
  • Questions answers


The webinar will be presented experience engineer Mr LEROY Elric, who work in the business unit team of Assemble Technologies.
