Axces Expansion Joints, also known as Stainless Steel Bellows or Compensator Bellows, are available in a variety of structures and versions. The steel bellows are the flexible element of every compensator. It must fulfill the requirement for good movability with simultaneous pressure resistance.
Variable parameters (wall thickness, number of plies, convolution geometry, number of convolutions) determine the pressure resistance, movement absorption, and spring rate (self- resisting force) of the bellows. One-ply, two-ply and multiply bellows are manufactured from various materials with different wall thicknesses. The calculation methods ascertain the stability limits. The ability to withstand buckling is the prime criterion for smaller bellows diameters, whereas in larger bellows diameters it is convolution stability.
Material qualities
Axces compensator bellows are manufactured from top-quality sheet metal. Different material qualities are used to cover the many operating conditions in various industrial applications. The outstanding characteristic of the steels and alloys is their particular resistance to chemically aggressive liquid media.
