“Amnitec” stainless steel expansion joints are used in lots of applications, where it concerns safety, health, environment, durability and lifetime. Bellows are made from stainless steel strip which is first welded to a thin walled tube and formed to a bellow afterwards.
Bellows are normally unbraided and capable to absorb axial, lateral and angular movements while being under low or higher pressures and temperatures.
Due to the construction techniques involved the bellows are relative light compared to equivalent non- metallic bellow alternatives in the market.
Stainless steel itself can withstand extreme variations in temperature ranging from very low to high temperatures i.e. from Cryogenic up to 600 °C. Stainless steel bellows are diffusion tight, have an excellent chemical resistance as well as high physical strength. On top of it, stainless steel bellows have very good corrosion characteristics.
Amnitec bellows and expansion joints are generally produced and assembled in sizes from nominal 40 mm (1-1/2”) up to nominal 2000 mm (80”).
Because of our broad package of different stainless steel bellows, they can be used in both static and flexible applications and installations where constant flexing or vibration is required.
