How to Get High Quality Stainless Steel Bellows?
A metal bellows expansion joint is considered to be an extension or compression of a piping system in its longitudinal axis, which means that the total length of the expansion joint is extended or compressed during the absorption of movement. Axial expansion joints designed to absorb large movements can contain one, two or more bellows in a single unit, or larger movements can be achieved by pretensioning or installing multiple expansion joints on a pipe section. Choosing the correct material for your metal bellows is critical. Stainless steel bellows are designed to withstand high pressures, high temperatures or critical media. Stainless Steel Bellows Stainless steel bellows are widely used where temperature, pressure or media prevent the use of rubber bellows. They are made of thin-walled tubes with the number of convolutions determining the available movement. For bellows units, only a relatively small amount of convolution can be safely designed before the unit becomes unstable
