SPRING HANGER

The variable load supports are spring devices that are generally used to hold up pipes and equipment which are subject to thermal expansions. The load born by the support varies as a function of the compression or the expansion of the spring, that are caused by the point of application movements. The variable load supports differentiate owing to various ways of fixing them to the load beating structure and are subdivided as follows:


Constant spring

Constant spring hanger are spring devices that are generally used to hold up pipes and equipment which are subject to thermal expansions. They have a constant reaction in whatever vertical movement position of the load application point: therefore they have rigidity equal to zero. They are employed when the vertical movement is remarkable; in this case, the utilization of variable load supports would cause strains higher than the admissible values.
