Series FFB Stainless Steel Bellows Expansion Joints

Stainless Steel Bellows Expansion Joints

Series FFB Free-Flexing Expansion Joints are manufactured using multi-corrugation metal bellows, and flanged or weld type end connections. Accessories such as tie rods, limit rods, flow liners, and covers can be added, depending on the application. Free-flexing expansion joints are used to control axial pipe movements that typically arise due to thermal expansion. Limited lateral offset, angular rotation, and vibration isolation can also be accommodated. Mid-corrugation bellows are an economical choice when average movements are experienced. High-corr bellows should be used to absorb greater movements. Where expected motions are greater than what a single bellows can accommodate, dual bellows with a center anchor base can be used. Bellows pressure carriers include low pressure exhaust bellows, 50 psi, 150 psi, and 300 psi. Single ply bellows are standard. Multi-ply bellows are well suited for those applications requiring low spring rate or where cyclical vibration may be a problem. Standard materials include T304, 321, and 316 stainless steel, as well as Inconel, Monel, and other alloys. Meets MIL-E-17813F Type 1, Class 1 and Class 2. Series FFB bellows expansion joints are designed and constructed per application to meet specific design requirements regarding combinations of pressure, temperature, motions, and cycle life. All Series FFB bellows are manufactured in accordance with the Expansion Joint Manufacturers Association (EJMA).
