RDF Series Rubber Expansion Joints are constructed with a double bellow flange configuration to provide flexibility and vibration control in piping systems, allowing movement in axial, lateral, and angular directions. The body is manufactured from high-quality synthetic rubber for added strength and durability. The joints reduce the transmission of noise and vibration while relieving stresses caused by thermal expansion and system movement. Constructed from corrosion resistant materials, they offer reliable, long term operation and enhanced protection for connected equipment and piping.
Normally used in pumps and piping
To absorb the vibration and misalignment correction in piping
Fluids for standard construction: Water (cold, hot or salt), weak acids, compressed air, etc.
• Reduces noise and vibration • Eliminates piping misalignment • Eliminates stress due to thermal expansion • Allows for greater axial, transverse and angular movements • Corrosion resistant materials • Above expansion joints are suitable for a vacuum rating of: 25 inches Hg • Above expansion joints are suitable for temperature range: -4 to 212 0F • Floating flange drilling standard as per customer’s requirement (ANSI, BS, DIN, JIS)
