Functional Purposes of Pipe and Hanger Supports
FIXED POINT / ANCHOR
Non-Welded Type (FIX POINT)
Welded Type (ANCHOR)
SUMMARY OF TYPES OF SUPPORTS
A SUPPORT CAN BE
- Simple Rest
- Rigid support
- Spring support
- Simple Guide
- Simple Axial Stop
- Rest and Guide
- Rest and Axial Stop
- Guide and Axial Stop
SELECTION OF SUPPORT UNDER DIFFERENT LOAD CONDITIONS
SHOE VENDOR SADDLES
- Variable Springs
- Constant Springs
HYDRAULIC SHOCK AND SWAY SUPPRESSOR
SHOE VENDOR SADDLE
COMBINATION OF SPRINGS
Effective under either tensile or compressive force. Can be installed in any spatial orientation.
SWAY STRUT IN VERTICAL ORIENTATION
COMBINATION OF STRUTS
HYDRAULIC SHOCK AND SWAY SUPPRESSOR (SNUBBER)
SELECTION CRITERIONFor use on piping systems or equipment when unrestrained thermal movement must be allowed, but which must be restrained during impulsive or cyclic disturbance.
Preferred usage, with standard settings, to prevent destructive results due to earthquakes, flow transients, or wind load. For absorbing the continuous thrust resulting from safety valve discharge blow-off.
EXAMPLES OF SNUBBERS
Dead load, live load, wind, seismic and hydro test loads need to be considered while designing supports.
Rest, guide and axial supports are the three basic schemes of supporting. A combination of any two or all three may be used for supporting.
High temperature, high pressure and associated phenomena make the steam system supporting critical.
Different type of supports are available under different types of loading conditions.
