Metal Hose Assembly:
Terminology:
| Specification |
According to which the hose assembly is manufactured |
Annular Core
|
Designed so that each convolution is a complete circle or ring |
| Close Pitch |
Less spacing between the corrugations, thereby giving longest fatigue life
and minimum bend radius |
| Braid |
Woven wire sheath placed over hose which prevents elongation of the hose
under internal pressure |
| Fittings |
Parts attached to the ends of metal hose so that it can be connected to
other components like flanges, unions, stub ends, nipples |
| Constant flexing bend radius |
The minimum radius to which a hose can be repeatedly bent and render
satisfactory flexure life |
| Operating conditions |
Pressure, Temperature, Media, Motion and application involved |
| Max. Test Pressure |
Max. Pressure for testing purpose. Based on 150% of the max.
working / design pressure |
| Media |
Material conveyed by the hose assemblies such as chemicals, gases,
liquids |
| Working temperature |
Temperature which hose is subjected to during operation |
| Corrosion Data |
Contact KFI or any NACE standards |
| Rated Burst Pressure |
The pressure at which the hose assembly can be expected to fail |
| Safety Factor |
Difference between working pressure and rated burst pressure |
