Protecting Fluid Circuits with Edge-welded Bellows

Edited by Paul J. Heney, Editorial Director Compensating for expanding fluid protects equipment and prevents leaks In many fluid power and fluid-handling applications, the gas or liquid inside equipment and lines can expand beyond normal design limits. This can be due to machine operations or reactions to changes in the environment—including temperature and pressure. Expanding

Dampers Show Flexibility in Retrofit of London’s Millennium Bridge

by Douglas P. Taylor When the Millennium Footbridge opened to the public on June 10, 2000, it was the first new bridge across the River Thames in historic London in more than a century. Nearly 100,000 people used it in its first day of operation. But a mere two days later, it was ordered closed

The Technology behind Edge Welded Metal Bellows

Coupling Tips

Edge welded bellows are manufactured by welding stamped, metal diaphragms into a long, flexible assembly. The key to the performance of the edge-welded bellows is the thickness and ripple profile of the metal diaphragms. The pressure, stroke length, spring rate and temperature help to determine the material and the thickness of the diaphragm required to […]
