Formed bellows are produced by reworking tubes, normally produced by deep drawing, with a variety of processes, including cold forming (rolling), and hydroforming. Welded bellows (also called edge-welded, or diaphragm bellows) are manufactured by welding a number of individually formed diaphragms to each other.
Which is the material used for bellows?
Bellows can be manufactured from a variety of stainless steels, with 300 Series steels the most common. Stainless steel has excellent tensile strength, making it easier to maximize stroke and minimize package size. Stainless steels also have excellent corrosion resistance in multiple environments and media.
What is a bellows assembly?
What are Bellow Assemblies? Depending on your specific application needs, custom bellow assemblies are designed to bend, extend or compress to absorb the angular and axial movement of the application.
What does a bellow do to a fire?
A bellows is a bag-like device with handles that's used to blow air onto a fire to keep the flame burning. If you have a fireplace in your house, you might have a bellows too. The kind of bellows that provides extra oxygen to a dwindling fire is similar to other types of bellows: they all involve a bag of air.
Why use bellows in piping?
Expansion joints (bellows) Expansion joints are installed in a piping system to absorb vibration and shock. They also have advantages such as reducing the noise and compensate caused by misalignment. Special expansion joints can also be designed for thermal expansion in hot applications.
How did bellows work?
Bellows have two handles which, when pulled, force the chamber to "inhale," drawing air inside itself for storage. When the handles are pushed downward, the air chamber forces the air out through the nozzle. Air blows out of the nozzle and onto a small fire or smoldering log to stoke the flames.26 Sept 2017

What were bellows made of?
Medieval Era The classical medieval bellows was a device made from wood and leather and was used to push air into the fire to allow the furnace to reach a high enough temperature to make iron melt.19 Feb 2014
What is the purpose of a bellow?
The bellows are used to deliver additional air to the fuel, raising the rate of combustion and therefore the heat output. Various kinds of bellows are used in metallurgy: Box bellows were and are traditionally used in East Asia.
What is a bellow in manufacturing?
Metal bellows are elastic vessels that can be compressed when pressure is applied to the outside of the vessel, or extended under vacuum. They are used both for their ability to deform under pressure and to provide a hermetic seal that allows movement.
