FLEXILOOP flexible metal hose is designed to absorb movements in pipes in all three axes (x, y, z), has six degrees of freedom and can also absorb rotational movements. The FLEXILOOP design is an effective and safe method for absorbing movements caused by thermal expansion, differential settlement of two structures and seismic movements in hydraulic and fire fighting systems. The standard supply of FLEXILOOP flexible metal hose comes with ASTM A105 class 150 carbon steel flanges and ASTM A105 SCH 40 carbon steel elbows. In flexible metal hoses, the following terms should always be considered when selecting:
PS: Service pressure.
PD: Design pressure, normally 1.25 * PS.
Pma: Maximum allowable pressure. This pressure must be calculated for each application, it is always affected by the operating temperature and the dynamic factor of the application. We recommend to see our technical catalog of flexible metal hoses. Pma: PN * FT * FD PN: Nominal pressure, is the pressure given by each manufacturer and corresponds to a nominal value that is calculated for work at ideal conditions, ambient temperature and with a dynamic factor = 1.
The FLEXILOOP design, for special applications, can be supplied with flanges in different standards, such as DIN PN 10, PN 16, PN 20, or ASME B 16.5 CLASS 300, can also be manufactured with threaded terminals, and can be supplied in materials such as stainless steel series: 304, 316 and 316L.
