What Are Non-Metallic Expansion Joints?

Flexible connectors designed to absorb thermal expansion, movement, vibration, and misalignment in pipe and duct systems without imparting stress to nearby equipment are known as non-metallic expansion joints. They offer a lightweight yet sturdy solution when flexibility and corrosion resistance are crucial because they are made of high-quality fabric, elastomers, and PTFE materials.

These specialty joints are perfect for situations where conventional metallic joints would not be appropriate, particularly in systems with dynamic movements, corrosive environments, and temperature fluctuations.

Key Features & Benefits

• Exceptional Flexibility: designed to minimize reaction forces on linked pipework or supports while accommodating multidirectional movements, such as axial, lateral, and angular shifts.
• Corrosion & Chemical Resistance: Joint life is increased and maintenance requirements are decreased by the resistance of fabric, elastomeric, and PTFE materials against corrosion from harsh media.
  
  Thermal Movement Compensation: Easily manages temperature-related expansion and contraction, shielding systems from wear and strain.
• Vibration & Noise Control: The flexible design enhances overall system performance by reducing noise and vibration.
• Lightweight & Easy Installation: These joints are far lighter than their metal counterparts, making them simpler to move, install, and swap out.
