Expansion joint flanged type ZKB DN80 149B12556C

Flexible expansion joint – vibration and noise reduction in installations

The ZKB connector is a reliable solution for damping vibrations, compensating for changes in length of installations, and reducing noise in piping systems. Made of high-quality materials, it provides effective protection and extends the life of the entire installation. It is a key element wherever vibrations, temperature changes or acoustic isolation are present.

Construction and application

The ZKB connector is characterized by a rubber-flanged design, which provides flexibility and effective vibration absorption. It is used in installations with a maximum working pressure of Pnom 1.6 MPa and a temperature of up to 95°C. The connector flanges are drilled according to PN10 and PN16 standards, which facilitates installation and ensures compatibility with various piping systems. This makes it suitable for both residential and industrial construction.

• Compensation for expansion and contraction: Allows for free changes in installation dimensions caused by temperature fluctuations, minimizing stress in pipelines.
• Vibration damping: Reduces the transmission of vibrations generated by equipment (e.g., pumps, fans) to the building structure or other installation elements.
• Noise reduction: Reduces the noise level generated by the flow of medium in the pipeline and the transmission of noise to the surroundings.
• Protection against electric current conduction: Rubber insulation prevents galvanic corrosion in the event of stray currents.
• Versatility: Can be used with various media (check compatibility with operating parameters).

Product characteristics and benefits for the installer

The ZKB connector is easy to install thanks to the flanged connection. Construction from EPDM or NBR (depending on the version) guarantees resistance to many chemicals and a wide range of operating temperatures. The galvanized steel flanges provide durable corrosion protection. It is worth noting the possibility of ordering flanges made of stainless steel (304, 304L, 316, 316L) and PN25 or ANSI 150 drillings – these options expand the scope of application of the connector. This gives the installer a flexible solution tailored to the specific requirements of the project. Additionally, locking rings are available for vacuum installations.
