The addition of Belleville International’s Belleville Spring Flange Washers to a flange joint for live loading is a great solution to keep fugitive emissions below mandated levels. The role of the washer is to increase the elasticity of the joint, therefore reducing the amount of relaxation.
EPA statistics show that 31% of uncontrolled VOC emissions from a petrochemical facility originate from flange connections. It is also estimated that 50%-80% of all flange leaks are from bolt preload loss.
We offer stock materials: H13, Inconel 718 and 17-7 Stainless, as well as custom materials and bolt stresses for everything from Heat Exchangers, High Temperature and Cryogenic Flange Bolting applications.
