Constant load spring supports

Constant Supports

Constant-load elastic supports are devices used to support the weight of pipes that, due to thermal variations and other factors, exhibit vertical displacements at the support points. Ca.STIm. 2000 constant-load supports essentially consist of a helical spring, a bellcrank connected to the spring by a jointed tie rod, and a frame. The kinematic mechanism is designed such that, for a certain rotation of the bellcrank around the main pin, the load C counteracting the action of the spring remains constant, given by:

C =k*(R*h*b)/c

in which:

C = load on the pipe

k = constant

R = spring stiffness

h = defined geometric value

b = variable geometric value
