Expansion Joints Design & Maintenance Training Course

Course Overview

Learning Objectives

• Analyze the functions of expansion joints and the consequences of expansion joint failures, drawing lessons from major incidents, on Day 1.
• Identify expansion joint types, including metallic bellows, rubber, fabric, and slip-type joints, and their applications and limitations.
• Compare metallic bellows configurations, including single, universal, hinged, gimbal, pressure-balanced, and tied designs.
• Apply recognized industry standards for expansion joints and relevant piping and pressure vessel code requirements.
• Calculate axial, lateral, and angular movements and select appropriate expansion joint configurations.
• Evaluate pressure thrust and design anchoring and guiding arrangements, including main anchors, intermediate anchors, and guide spacing.
• Assess spring rates, loads on equipment nozzles, and interaction with piping flexibility and stress analysis.
• Evaluate instability, including column squirm and in-plane instability, and fatigue life under cyclic conditions.
• Select bellows and joint materials considering temperature, pressure, corrosion, and stress corrosion cracking risks, and specify liners and covers.
• Prepare expansion joint specifications and data sheets and review manufacturer designs and documentation.
• Apply correct installation, cold setting, restraint removal, pressure testing, and commissioning practices.
• Inspect expansion joints, diagnose failure modes, and plan repair, replacement, and maintenance strategies by the end of Day 5.
