Loose flanges Axial expansion joints are expansion joints that absorb mainly longitudinal movements  - axially along a straight section of pipe.

Advantages of axial expansion joints

• Simple means of compensation
  
• Smaller space requirements
  
• No alteration of flow movement
  
• Movement possible in any direction
  
• No redirection of pipe work required
  
• Low unit costs
  

Disadvantages of axial expansion joints

• High axial forces at higher pressures
  
• Strong fixed points and good axial pipe guides required
  
• Small and medium movement absorption
  
• For large expansion movements several axial expansion joints are required
  
• On long stretches many fixed points and pipe guides are required
  
• Axial expansion joint variants
