Description
Aquatherm 9793315722 3" Steel ANSI Flange Ring
For transitioning between larger sizes of pipe, attaching prefabricated sections, or connecting to pumps, valves and other mechanical equipment, Aquatherm produces fusible flange adapters with steel flange rings. The rings are designed to match up metric pipes with ASME/ANSI bolt patterns.
Aquatherm recommends using a full face rubber (black EPDM or red SBR), 1/8 inch minimum thickness gasket with its flanges. Viton® gaskets may also be used if needed for chemical resistance. Ring gaskets, may cause blow-outs during pressure testing. Ring gaskets are also more susceptible to leaking if the flanges and connected piping are not aligned properly during installation. Refer to the Aquatherm Installer Manual and Technical Bulletin 201405B for flange bolt-up requirements, including torque, quantity size, tightening sequence and procedures.
