Vibration Damping Flange Spacer - Series W8 - DN 80; L=70mm; EPDM BRA.W8.500

Product detailed description

Vibration damping flange spacers are essential components in mechanical systems where vibration isolation is required. They are commonly used in heating, ventilation, and air conditioning (HVAC) systems, as well as in water supply and compressed air installations. These spacers are installed between flanged pipe sections to absorb mechanical vibrations and reduce noise propagation through the piping network. In industrial and commercial buildings, they help maintain system integrity and improve acoustic performance by isolating mechanical components from structural elements.

Installers working on systems with pumps, compressors, or heat exchangers often encounter the need to incorporate vibration damping solutions. These spacers are particularly useful in systems where mechanical movement can lead to fatigue in pipe joints or where noise levels must be controlled for compliance with building regulations. The use of vibration damping flange spacers ensures that the system operates smoothly and with minimal wear on connected components.

The technical parameters of this vibration damping flange spacer are critical for proper system integration. The nominal diameter (DN 80) ensures compatibility with standard pipe sizes, while the PN 10 rating indicates the maximum allowable pressure for the flange connections. The operating temperature range of -10°C to +100°C allows for use in a variety of environments, including those with seasonal temperature fluctuations. These parameters are essential for correct sizing and selection in accordance with system design requirements.

Installation and connection

Installation of the vibration damping flange spacer requires careful alignment of the flange faces to ensure a secure and leak-free connection. The spacer is positioned between two flanged pipe ends, with the EPDM sealing element compressed to form a tight seal. The flange connections are secured using standard bolts and nuts, following the manufacturer's torque specifications. It is important to verify that the flange surfaces are clean and free from debris before tightening. Common installation mistakes include misalignment of the flanges, over-tightening of bolts, and failure to check for proper sealing after installation.

Compatibility and accessories

This vibration damping flange spacer is compatible with standard PN 10 flanged pipe systems. It is designed for use with water-based media, including those containing up to 50% glycol. Additional components such as bolts, nuts, and gaskets may be required for installation, depending on the system configuration. No related products are specified for this model.

Technical background for designers

The vibration damping flange spacer operates by absorbing mechanical vibrations through the flexible EPDM sealing element. The galvanised steel flanges provide a rigid connection between pipe sections, while the EPDM material allows for controlled movement and energy dissipation. The integration of this spacer into a system helps reduce stress on pipe joints and minimises the risk of fatigue failure. The service life and efficiency of the spacer are influenced by factors such as operating temperature, media compatibility, and the frequency and amplitude of vibrations in the system.

Service and operation

During operation, the vibration damping flange spacer requires minimal maintenance. However, periodic inspections should be conducted to check for signs of wear, leakage, or degradation of the EPDM sealing element. If any issues are detected, the spacer should be replaced to maintain system performance. No specific service intervals are provided in the technical data.
