MIL-PRF-32306

Abstract

This specification covers requirements for a preformed one-piece construction flex hose assembly (continuous hose assembly) with captured end-flanges that are free to rotate (spin). Pressure capabilities of any hose meeting the first article tests prescribed herein are acceptable, however, the nominal pressure capability, which will vary by hose size, is expected to range around 150 pounds per square inch gauge (psig). Details concerning vibration dampening characteristics are beyond the scope of this document (see 6.1). <br><u>Classification.</u> Preformed hose assemblies are of the type, size, and shape specified in the solicitation or contract (see 6.2).<b><u>Intended Use:</u></b> The intended use is for U.S. Navy Surface Ships. The hose products covered under this specification are for shipboard machinery motion and vibration isolation in new applications and for back-fit into existing installations. Prefabricated one-piece construction dogleg flex hose assemblies compensate for relative motion or excessive vibration between equipment and piping. Preformed hose assemblies in compliance with this specification are intended to convey fluids to and from equipment where motion between connections must be accommodated. Properly designed hose assemblies handle vibration as well as excursions from shock without damage. It is expected that these hose assemblies will be suitable for a variety of fluid applications. Guidance for use of preformed hose assemblies for their noise attenuating properties is provided in S6430-AE-TED-010.<br>
