Design and Operating Principle

Rubber expansion joint with tie rod designs are optimized with an elastomer body working together with tie rods to provide controlled movement absorption.

The tie rod system limits axial forces generated by internal pressure while allowing controlled lateral and angular movements. This reduces mechanical loads on the piping system and protects equipment connections.

Flanged connections ensure easy installation, while the elastomer body helps dampen vibration and shock loads.

Performance Advantages

• Limits axial forces generated by internal pressure
• Protects piping systems and equipment connections
• Helps reduce anchor loads
• Ensures controlled and safe operation
• Effectively reduces vibration and noise
• Minimizes mechanical stresses
• Long service life
• Easy installation capability

Operating Values

Operating Pressure

• Maximum 16 bar
• (depending on DN size, tie rod design, and elastomer type)

Operating Temperature

• EPDM: -20°C / +120°C
• NBR: -10°C / +100°C
• Neoprene: -20°C / +100°C
• Viton: -10°C / +180°C

Movement Capabilities

• Axial Movement: ±5 mm – 10 mm
  (limited by tie rod system)
• Lateral Movement: ±8 mm – 15 mm
• Angular Movement: 5° – 8°

Note: The tie rod system restricts axial movement. Movement capacities and operating values may vary depending on product diameter (DN), pressure class, and tie rod configuration.
