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 for relatively large bellows forming (up to 4500mm). Although the forming method is different, both ways are providing efficient ways of uniform structure with adequate dimensional accuracy.

Rubber Expansion Joint

이미지
Rubber Expansion Joints MEGAFLEXON Rubber expansion joints have been specified and used for many years by consulting engineers, mechanical contractors, pressure vessel designers, plant engineers, and turn-key construction firms. They are installed to accommodate movement in piping runs, protect piping from expansion and contraction, and ensure efficient and economical on-stream operations. Rubber expansion joints are a specifically engineered and designed section of pipe that is flanged and is able to be inserted within a rigid piping system with the goal to be the achievement of one or more of the following. Rubber expansion joints, designed by engineers and fabricated by skilled craftsmen, are used in all systems conveying fluids under pressure and/or vacuum at various temperatures: Spool Type Rubber Expansion Joints                Features                ● Hand-built construction       ...

Bellows Manufacturing

이미지
Bellows Manufacturing Megaflexon manufactures bellows using an expanding mandrel (punch forming) method followed by a finish rolling. A rectangular sheet is sheared and rolled into a tube. The tube is welded using an auto flat-bed welder with no filler metal added.  The longitudinal seam weld is then planished back down to the base material thickness.  Dye penetrant, X-ray, or air testing is performed at this stage.  After testing, the convolutions are punched individually drawing material from the top and bottom of the tube.  The drawing process eliminates any possible thinning in the bellows material. Then, re-rolling process and then trimming process will follow. In addition to this, Megaflexon manufactures bellows using a variety of machines, including hydraulic forming machines and automatic hydraulic forming machines. ▲ Automatic Longitudinal Seam Welding Machine ▲ Hydraulic Mandrel Punch Forming Machine (Max. : 4,500mm) ▲ Automatic Hydraulic Forming Machine (M...
