Stainless steel corrugated pipe, as a flexible and pressure resistant pipe fitting installed in liquid transportation systems, is used to compensate for the mutual displacement of pipes, machines, and equipment connection ends, absorb vibration energy, and can play a role in vibration reduction, noise reduction, etc. It has multiple characteristics such as good flexibility, light weight, corrosion resistance, fatigue resistance, and high and low temperature resistance.

The stiffness of a metal bellows is the load value required to produce a unit displacement of the metal bellows or other elastic components, which is called the stiffness of the component and is generally represented by "K". If the elastic properties of the component are nonlinear, the stiffness is no longer a constant, but changes with increasing load. The stiffness given in the design and calculation of elastic elements with nominal stiffness is called nominal (or rated) stiffness. It has errors with the measured stiffness of the element, especially for elastic elements with nonlinear elastic characteristics. The nominal stiffness represents the stiffness at which point on the curve, which needs to be carefully considered. Generally speaking, it is best not to directly use the design calculation value for nominal stiffness, but rather to use the corrected value of the product prototype after testing. The allowable deviation of stiffness for a batch of elastic components during testing is the allowable range of stiffness dispersion. For the same batch of elastic components, the stiffness of each component of the stainless steel metal hose is not the same, with a dispersed range. In order to ensure the performance of the components, it is necessary to have a limit on the range of stiffness dispersion. For elastic sensitive components, the stiffness tolerance requirement is limited to within+/-5% of the nominal value; The stiffness tolerance of corrugated pipe elastic components used in general engineering can be limited within+/-50%.
