The Constant Spring Hanger Supports are principally used to support pipes & ancillary equipments subjected to vertical movement due to the thermal expansion at locations where transfer of stress to other supports or equipment can be critical. Techno Industry incorporates the latest design concepts, in order to manufacture the Constant Spring Hanger Supports according to the needs of modern industry. According to MSS, the maximum recommended variation from the operating load for variable spring hangers is 25 %. Constant Spring Hanger Supports are use when this variation exceeds 25%.?
The working of Constant Spring Hanger Support is based on a simple mechanical principle, which is given below:?
To produce a constant supporting effect the load moment about the main pivot must be counter- balanced by an equal spring moment throughout the travel range.
Referring to the diagram, take three positions of the load travel- Top, Middle, Bottom, and then equate the moments of these points about the main pivot.
The equations are given below:
