A e r o q u i p O f f e r s Rubber Insert Sound Isolation Couplings For S h i p b o a r d A p p l i c a t i o ns

Aeroquip's RISIC 3 and 3HT rubber insert sound isolation couplings for shipboard piping applications, are designed to attenuate sound transmissions of machinery and piping, while accommodating various types of pipe movement. Aeroquip RISIC 3 couplings have been qualified for ship water and oil service to 150 psig and + 160°F. Aeroquip RISIC 3HT couplings are approved for feed water service to 150 psig and + 250°F.

Qualification tests have proven the RISIC 3 and 3HT couplings meet or exceed U.S. Navy requirements for acoustical performance, mechanical impedance, flex pressure cycling, accelerated aging and hydrostatic burst pressure.

Aeroquip RISIC 3 and 3HT couplings offer improved performance by using the natural ability of an elastomer to dampen vibration and sounds, while allowing angular flexibility of ± 5° (10° total). Metal reinforcements are molded within the elastomeric bearing to support the internal pressure and axial loads.

Offered in sizes from 3 inches through 10 inches, Aeroquip RISIC 3 and 3HT couplings are available as either complete new units or conversion kits for RISIC 1 units Complete information, including specifications and technical data, cross reference part numbers and materials for Aeroquip's RISIC 3 and 3HT rubber insert sound isolation couplings, can be found in Aeroquip Bulletin 8313.
