1. Storage years of metal bellows

　　The method of "first in first out" can be adopted. If the storage time of metal bellows needs to be extended, such as one year, all the metal bellows should be inspected before use.

　　2. Ozone environment of metal bellows storage

　　Ozone will damage rubber materials. There should be no ozone releasing substances in the storage environment, such as mercury lamp, mercury tube stored in metal bellows, high voltage electrical equipment, electric motor and other substances that may cause sparks and static electricity.

　　3. Storage environment of metal bellows storage

　　All pipe fittings including metal bellows shall not expose or touch solvent, fuel, oil, grease, volatile matter, acid substance, disinfectant, etc. In addition, copper, metal bellows stored in iron and manganese and other metal materials will also be harmful to rubber.

　　4. Storage temperature of metal bellows

　　The storage address shall meet the interval with heat source (including heating equipment and metal bellows) and meet the temperature specification in article 2.3. If you can't insist on meeting the interval, install the heat shield.

　　5. Electric field and magnetic field of metal bellows storage

　　There should be no change of electromagnetic field in the storage situation. The change of electric field or magnetic field will make the metal bellows wind metal coil produce current, which will cause the metal bellows to heat up. Such as high voltage cable and high frequency generator can produce such strong electric field and magnetic field.

　　6. Storage conditions of metal bellows

　　Metal bellows should not be artificially compressed, elongated or excessively deformed during storage. Do not touch with any sharp metal. Bellows should be stored in dry environment. If conditions permit, they should be stored in separate areas. When the metal bellows are rolled up and stored, they should be placed horizontally instead of overlapping each other.

　　7. Storage of metal bellows

　　It is necessary to ensure that the metal bellows are intact when leaving the warehouse and meet the operating conditions. Therefore, different metal bellows should be marked accordingly. In special cases, if the storage time of metal bellows is long, check the metal pipe head carefully before leaving the warehouse.

　　Metal bellows have outstanding flexibility, fatigue resistance, high pressure resistance, high and low temperature resistance, corrosion resistance and many other characteristics. Compared with other bellows, the service life of metal bellows is much longer, so it has higher inductive economic benefits. With the development of modern industry, the demand for metal bellows is increasing.
