As many engineers know, the rotating parts of a pump produce vibrations that can become strong enough to pull fixtures out of the ceiling and damage property. To help prevent these powerful vibrations, one option that builders choose are stainless steel bellows pump connectors. At N.H. Yates we are proud to be a manufactures representative of Flex-Hose Bellowsflex Metal Bellows Expansion Joint. The Bellowsflex is an excellent choice for absorbing vibrations, compensating for misalignment at equipment connections and accommodating thermal growth in many service conditions and applications.
Why Choose the Bellowsflex from Flex-Hose?
The standard Flex-Hose Bellowsfelx bellows element is manufactured with 321 stainless steel which is it not susceptible to corrosion or rust even after reaching temperatures up to 900º C or about 1,650º F. In addition to the 321 stainless steel, the Bellowfelx is available in other heat and corrosion resistant alloy materials for higher temperature applications. The Bellowflex comes from the factory with a standard pressure rating of up to 300 PSI. However, the maximum system test pressure is can be up to 1.5 times the working pressure. And of course, the Bellowflex can be equipt with accessories such as tie rods, limit rods, flow liners, and protective covers and/or shrouds. Finally, Flex-Hose offers the Bellowflex with multi-ply bellows for added flexibility and endurance. The reduced thickness of the individual bellow plies results in less bending due to the axial motion which increases the life of the bellows.
Bellowsflex comes in sizes 2 thru 60 inches in diameter and pressure ratings 50, 150, 300, and 600 PSI full vacuum service. In addition, plate flange, raised-face forge Slip-On Flange, Vanston “Floating” Flange, pipe weld ends.
