the installation position is marked on the travel scale.

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. This ensures no abnormal or excessive forces, due to out of balance supporting effort, is transferred to the pipework in its stressed working condition. In keeping with generally accepted practice, it's recommend that the actual pipe load is correctly supported when the pipe is in its normal working position. It is therefore usual to select variable spring supports on this basis.
Most national standards do limit the load variation to maximum of 25%.

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. The travels stated are the maximum working range of the springs. Standard ranges of variable spring supports are produced in four basic travel ranges 35mm, 70mm, 140mm and 210mm. For relatively small displacements (up to about 75mm) the variable spring support is recommended. which give rise to vertical displacements should be supported by a resilient device which will absorb/accommodate the movement. Pipework and/or vessels subject to temperature change or subsidence, etc. The piping must therefore be supported in a correspondingly elastic manner so to compensate slight vertical displacements in the piping, Spring components are used as supports. To prevent constraints in the system, thermal expansion in the piping and the other piping components must not be hindered. Dynamic supports support the pipe in vibrations, seismic, winds and even take loads in working conditions. Contact National Pipe Hanger Corporation's New Jersey headquarters or Maryland branch for special pipe support requirements including: other pipe sizes and types, dimensional requirements, installation methods, finishes, etc.There are different types of dynamic or flexible support. In addition to a wide range of high-quality hangers, National Pipe Hanger Corporation offers custom options backed by our skilled engineers. (UL), and Federal Specifications (WW-H-171E).
