Solon Flange Washers
Solon Flange Washers help create a more reliable flange assembly by maintaining residual gasket/bolt load and ensuring even load distribution. We maintain a stock supply of H-13 Tool Steel, 17-7 PH Stainless Steel, and Inconel 718 flange washers. As a flange washer manufacturer, we can also produce custom flange washers using 17-4 PH Stainless Steel, Custom 450, Waspaloy, and more upon request.
Flange Washer Size Options
Solon imperial and metric flange washer size options include:- Imperial: 3/8” – 4”
- Metric: 6mm – 110mm
TORQUE CALCULATION
Imperial: (ft. - lbs.) = .2 x Bolt Diameter (in.) x Load (lbs.) / 12
Metric: (N-m) = .2 x Bolt Diameter (mm) x Load (N) / 1000
Premium Standard & Custom Flange Washers
Up to 92% of all flange leaks are caused by insufficient bolt preload. Solon Flange Washers are designed to maintain sufficient bolt tension and resultant gasket pressure in high-temperature and high-pressure applications where safety and emission containment are top priorities. Standard and custom Belleville spring and flange washer combinations are designed to provide additional clamping pressure and support.Flange Washer Material & Finish Options
