Various Type of Bellows
THE BELLOWS Bellows may be either U-shaped or toroidal (Ω-shaped) in cross-section. The U-shaped bellows is superior for great deflection but has a lower pressure capacity for the same material thickness. Conversely, toroidal (Ω-shaped) bellows is limited to small deflection but has a higher pressure capacity. The use of external reinforcement of the U-shaped can provide a combination of great deflection and high internal pressure capacity, and the pressure capacity can also be increased by the use of multi-ply construction or by increasing the material thickness of the bellows. The U-shaped bellows is mostly manufactured and used in industries, and the Ω-shaped bellows has limited application in case of high pressure and small deflection requirements. Megaflexon manufactures bellows using a variety of methods, such as hydroforming and hydraulic mandrel punch forming etc. Hydroform process is used for relatively small bellows forming, and hydraulic mandrel punch forming process is used...
