Flange Washers

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.                                                                                                    

Designed and manufactured by Solon Manufacturing Co., Solon Flange Washers withstand extreme temperatures as well as corrosive environments. Whether you have a custom material specification or unique application challenges, Solon’s
full-service design engineering and production teams can help you with your requirements.

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
