Flexobat: Rubber Expansion Joint With Turnable Flanges

The document describes the Flexobat rubber expansion joint. The Flexobat has turnable flanges and is used to compensate for thermal elongation, correct misalignments, and isolate vibrations in pipe systems. It has an EPDM inner and outer layer reinforced with nylon fabric. Standard flanges are mild steel. It can operate between -10°C and 80°C at pressures up to 16 bar, depending on temperature. Movement capabilities include 12mm of compression, 10mm of elongation, and 12mm of lateral deflection.

Notes
‹ Higher temperatures affect movement and pressure. As temperature increases, rated values must be reduced accordingly.
‹ Pressures shown are recommended "operating", test pressure is 1.5 times "operating" pressure.
‹ Vacuum rating is based on neutral installed length without external load. Products shall not be installed "elongated" on vacuum
applications.
‹ Expansion joints may operate in pipelines or equipments carrying fluids at stated temperatures and pressures.
Normal precautions shall be taken to make sure these parts are installed correctly and inspected regularly.
Precautions shall be taken to protect personnel in the event of leakage or splash.
‹ For other kinds of applicable fluids, except the above, to which the rubber joint becomes applicable, please kindly consult your
supplier or manufacturer.
