DISC SPRINGS FOR FLANGE APPLICATION
 
Disc Springs are an elastic mechanical elements. When used in bolt joints that are subject to thermal or mechanical shock, they deflect and move with the bolted joint. Hence, they compensate for developed looseness. The reactive power of the disc spring serves to keep the bolt joint tight under all conditions. Principal applications include piping joints, valve and pump connections, and others in the petrochemical field.
 
A principal cause of flange leakage is abnormally high load produced by thermal expansion and contraction of a bolted joint Generally, flanges are under static load conditions. However, in large piping systems, there may also be mechanical shock from compressor related piping. Thermal and mechanical shock differential can cause variation and yielding in bolt loads. To protect against these conditions, always use Disc Springs under the nut or bolt head.

Prestressing or torquing the bolt at factory installation is not sufficient to protect the flange joint under unexpected temperature variations and mechanical shock loads in the field. By absorbing peak stresses, Disc Springs prevent damage to the bolt, gasket and joint.
