Flange Washers Engineered for Flange Applications

Certain industries that utilize piping flange joint assemblies, such as petrochemical, dictate a low tolerance for fugitive emissions. Live loading,which is a process imperative to controlling gasket leaks in piping and refining operations, depends on the mission-critical performance. It is estimated that up to 92% of all flange leaks are caused by insufficient or loss of bolt preload.

Solon Flange Washers are designed to maintain sufficient bolt tension and resultant gasket stresses in high-temperature and high-pressure applications where safety and emission containment take priority.

Solon Flange Washers are simply Belleville springs that are designed to be used in flange applications. The springs are engineered to fit into flange designs and the loads are typically higher than standard Belleville washers.

ANSI Flange Live Loading Calculator

Increase the value of the live loading system by using our calculator tool to quickly design a live loading system for flange applications. This interactive tool assists with the design of the flange washer system based on inputs relative to flange size, environment and bolting information under normal assembly conditions. Output includes the recommended Solon Flange Washers, stacking arrangement and quantity recommendations and assembly notes, along with quick access to specification reports and the capability to submit a quote request directly to our sales team.

Features & Benefits of Solon Flange Washers:

  • Once installed, they don't have to be retorqued
  • Eliminate the effects of differential thermal expansion
  • Increase the elasticity of the bolting system by a factor of  7 to 15 times  
  • Economical alternative to costly system enhancements  
  • Maintain bolt integrity by maintaining the contact pressure between the flange and gasket surfaces
