The stainless steel bellows are extensively used to increase the internal volume of bellows and to reduce the internal pressure. It is used for pressure relief during the expansion and the contraction of the bellows, and to reduce the risk of bursting bellows during the expansion.
The expansion bellows, a cylindrical bellows with one circular end, that is, it is wrapped only around the circular circumference of the cylinder, is a highly specialized manufacturing process which involves making a series of radial cuts in a metal. The steel bellows is a cylindrical metallic structure that is employed to expand or decrease the volume of a cylindrical space, such as the air-filled space of a balloon. It is also capable of maintaining a specific volume.
The application of the ss expansion bellows is
