Introduction: Stainless steel bellows, as a flexible compression pipe fitting, is installed in the liquid conveying system to compensate for the mutual displacement of the connecting ends of pipes, machines and equipment, and absorb vibration energy. The stainless steel corrugated pipe has the functions of shock absorption, noise reduction, good flexibility, light weight and resistance to vibration

Stainless steel bellows, as a flexible compression pipe fitting, is installed in the liquid conveying system to compensate for the mutual displacement of the pipe or machine and equipment connection ends and absorb vibration energy. The stainless steel corrugated pipe has the functions of shock absorption and sound attenuation, and has the characteristics of good flexibility, light weight, corrosion resistance, fatigue resistance, high and low temperature resistance, etc.
The connection methods of stainless steel bellows are divided into the following categories: flange connection, welding, screw thread connection, quick joint connection and small diameter Metal hose Generally, screw thread and quick connector are used for connection, while flange connection and welding are used for large diameter.
Stainless steel bellows, as a kind of flexible compression pipe fitting, is installed in the liquid conveying system, which is used to compensate the mutual displacement of pipeline or machine and equipment connection ends, absorb vibration energy, and have the effects of shock absorption and noise reduction. It has many characteristics such as good flexibility, light weight, corrosion resistance, fatigue resistance, high and low temperature resistance, etc. The load value required by the stiffness of metal bellows to cause unit displacement of metal bellows or other elastic elements is called element stiffness, which is generally expressed by "K". If the elastic characteristics of the element are nonlinear, the stiffness is not a constant, but changes with the expansion of the load. Nominal stiffness the stiffness obtained in the design and calculation of the elastic element is called the nominal (or rated) stiffness. It has deviation from the measured stiffness of the element, so it is an elastic element with nonlinear elastic characteristics. The nominal stiffness represents the stiffness at which point on the curve, it should be carefully considered. Generally speaking, the nominal stiffness should not be calculated directly from the design value, but should be corrected after the prototype test. Stiffness tolerance is the allowable range of stiffness dispersion when testing a batch of elastic components. For the same batch of elastic components, Stainless steel metal hose The stiffness of each element is different and has a dispersion range. In order to ensure the performance of the components, there must be a limit on the range of stiffness dispersion. For elastic sensitive elements, the stiffness tolerance is required to be limited within ± 5 of the nominal value; for general engineering bellows type elastic elements, the stiffness tolerance can be limited to + / - 50.
Stainless steel bellows generally adopt flange connection, screw thread connection, welding, quick joint connection, etc. small diameter metal hose generally adopts screw thread and quick connector connection, and large diameter generally adopts flange connection and welding connection. There is a certain tensile strength in the middle of the side buckle of the stainless steel threading hose, which can prevent the damage of the hose from exposing the lines laid inside the hose. The axial tension can bear more than 6 times of the nominal inner diameter. Application of stainless steel bellows: automatic instrument signal tube, automatic instrument wire maintenance tube; optical ruler circuit, industrial sensor, electronic equipment line protection tube; electrical circuit protection, thermal instrument capillary protection and hollow core high-voltage optical cable internal support point. Characteristics of stainless steel bellows: excellent flexibility, corrosion resistance, heat resistance, wear resistance, tensile resistance, water resistance and excellent electromagnetic shielding characteristics. Flexible, flexible and flexible in the middle of the hose, flexible and flexible in the middle.
