Vibro-Dämpfer Solutions India

Pipework and/or vessels subject to temperature change or subsidence, etc. which give rise to vertical displacements which should be supported by a resilient device which will absorb/ accommodate the movement. For relatively small displacements (up to about 75mm) the Variable Spring Support is recommended and for higher displacements constant spring support is more suitable.

We manufacture customized Spring Supports in four basic travel ranges: 35mm, 70mm, 140mm and 210mm.

The travel is the maximum working range of the springs. This full travel can be used providing the necessary calculations are carried out to ensure that the connecting equipment and pipework can withstand the large load changes that occur during pipe movement. Most national standards do limit the load variation to maximum of 25%. It is therefore usual to select Variable Spring Supports on this basis.

In keeping with generally accepted practice, we recommend that the actual pipe load is correctly supported when the pipe is in its normal working position.

This ensures no abnormal or excessive forces, due to out of balance supporting effort, is transferred to the pipework in its stressed working condition.

Whether this or any other principle is followed for the selection of Variable Spring Supports, care must be taken to ensure that sufficient travel is available in the spring assembly to permit free movement of the pipe within the required pipework movement range cold or hot.

The Supports are supplied set at the required preset load and preset and hydrostatic test stops are provided as standard (see images above). All preset load and hydrostatic test stops must be removed prior to operation of the equipment.

For getting customized spring supports please share following details for designing suitable solution:-
1. Operating Load.
2. Vertical movement and direction of movement, cold to hot (example: 20mm up).
3. Support Height requirement as per site conditions.
