Spring Rate

The spring rate of a bellows refers to the force required to achieve deflection. It is a key performance parameter for metal expansion joints (MEJ), as it determines how much resistance the bellows offers when deflected.
Spring rate depends primarily on the design dimensions of the bellows such as convolution depth, thickness, and diameter as well as the material properties used in manufacturing. A well-calculated spring rate ensures that the bellows can absorb thermal movements, vibrations, and mechanical stresses without compromising system integrity.
Accurate spring rate calculation is essential in selecting and designing bellows to achieve optimal flexibility while maintaining strength and durability in your piping system.
At LSI-MECH, our bellows are expertly designed to meet all customer spring rate requirements, ensuring precise performance and reliable operation across a wide range of industrial applications.
