Threaded internal flexible coupling type ZKT 6/4 inch 149B12571C

Expansion joint – protection of the installation and noise reduction

This ZKT type expansion joint, with a diameter of 6/4 inches, is a key element in installations where vibration damping, movement compensation and noise reduction are important. Its design allows for effective protection of pipelines against the effects of thermal expansion and vibration, which translates into a longer system life and user comfort. Made of high-quality materials – EPDM and galvanized steel – it guarantees reliability and corrosion resistance.

Construction and application

The ZKT joint is a rubber-flanged connection with an internal threaded connection. This design allows for easy installation in existing installations and ensures a tight connection. It is particularly useful in heating, water and industrial systems where temperature fluctuations or dynamic loads occur. Thanks to its properties, it effectively compensates for changes in pipeline length resulting from thermal expansion, minimizing stress in the system. Additionally, it dampens vibrations generated by operating equipment (e.g. pumps, fans), reducing noise and increasing acoustic comfort.

Key features and benefits

• Vibration damping: Reduces the transfer of vibrations from equipment to pipelines, protecting them from damage and extending their life.
• Movement compensation: Absorbs changes in pipeline length caused by thermal expansion or contraction, preventing stress build-up.
• Noise reduction: Dampens sounds generated by the flowing medium or operating equipment, improving the acoustic comfort of the surroundings.
• Corrosion resistance: Construction of galvanized steel provides protection against corrosive agents, guaranteeing long-term reliability.
• Wide temperature range: Can operate at temperatures up to 95°C (check the temperature/pressure chart for a specific application).
• High pressure resistance: Pnom 1.0 MPa ensures safe operation under typical operating conditions.
• Easy installation: Threaded connection facilitates installation and removal of the joint without the need for specialized tools.
• Protection against electric current conduction: The design limits the risk of stray currents flowing through the installation.

EPDM is used as a gasket material, and galvanized steel for the connection. The maximum working pressure is 1.0 MPa, and the maximum operating temperature is 95°C. It has an internal threaded connection and a nominal diameter of 6/4 inches.

Remember to properly secure the pipeline near the joint and avoid preloading the joint during installation – this is key to its proper operation and long life!
