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 is the purpose of a bellows?
bellows, mechanical contrivance for creating a jet of air, consisting usually of a hinged box with flexible sides, which expands to draw in air through an inward opening valve and contracts to expel the air through a nozzle.
What is a bellow system?

What is a bellow in engineering?
Flexible bellows, also known as expansion joints, are flexible elements that absorb movements in the pipe system. These movements they absorb are defined by axial, lateral, angular and universal movements.
What are bellows made of?
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 are machine bellows?
Designed to protect guide-ways and machine components and constructed using lightweight material, bellow covers are ideal for fast travel applications. Their high compression ratio also makes accordion way covers ideal in limited space.
What is a way cover?
Way covers keep chips and coolant away from the ballscrew, guiderails, and home switch. Machines can have three types of way covers. Roll Shade Style - EC Machines: Roll shade way covers use a tensioner to keep the rubber sheet rolled up on a spool.17 Nov 2021
