How to Produce Expansion bellows in a Manufacturing Unit

There are generally two different methods of producing expansion bellows. Some smaller bellows are formed on a machine that mass produces the parts on a large scale. If you have any gas appliances in your home there is likely a section of formed bellows where the gas attaches to your appliances. This flexible piping contains the gas inside, allows for easy alignment, and most importantly, reduces stress at the connection points. When containing flammable gasses in your home, reducing long term stress is a critical safety measure. Formed expansion bellows are also used in larger applications such as HVAC, and large piping systems.

On the other end there are welded bellows that may need a custom fabrication for each situation. With this method, each piece, called a diaphragm, of the bellows is custom cut and welded into the bellows needed for a particular situation. This can be made from any expansion able to be welded, but generally, non-corroding materials are used by the expansion bellows suppliers. Obviously, this is a much more expensive process and has many applications in medicine, heavy industry, defense, aviation and aerospace.

Expansion bellows are manufactured and sold by companies specializing in expansion joints and other piping systems. These couplings have proven to be versatile and to satisfy a variety of applications. Expansion bellows suppliers allow you to control fluid movement and containment in your system under a wide variety of pressures, thermal expansion and contraction, pulsations, vibration, equipment movement and convoluted routing requirements from the industrial unit.
