RUBBER EXPANSION JOINTS DOUBLE BELLOW FLANGE CONNECTION (RDF SERIES)
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)
