Shrinkage and elastic force of the stainless steel bellows stainless steel bellows from the manufacturing process to show that having a good compressibility, but extensibility far less compression. I.e. the bellows used in the compression direction of the long life and the short life extending direction, compression and elongation ratio (length ratio) is preferably approximately 4: 1. For the compression ratio to use when boundaries extending soul. Usually begin to stretch called the initial pressure means in terms of compression. When the external force, the resistance to bending corrugated tube variety, permanent deformation due to the expansion or contraction of boundaries as the maximum amount of stretching. Stretch ratio and the maximum percentage of the amount of stretching is called the stretch ratio of the amount. Define the elastic force is excellent resistance to bending corrugated pipe manufacturers, assume that a wave of bellows to stretch lmm 1kg force required. The ten wave bellows elastic force that is only one-tenth of the value, so stainless steel bellows to produce good sensitivity. Processing standard pitch generally result bellows, its pitch than the large waves, so it needs to be shaped compression, so the pitch is shortened, this approach is a bellows after forming, it still makes peak and crest length compression gently rely on, and then removed from the device. Standard pitch according to the thickness of the bellows tube varies, in most cases the heat treatment will produce spots, which affect the quality. An important issue here, bending resistance bellows type, the standard pitch is the amount of stretching, since external force generated telescopic bellows, the external force is removed and returned to the original standard pitch. When used in the measurement, control devices, have to be limited to the maximum amount of stretch the scope of corrosion corrugated metal pipe corrosion of metal bellows metal hose and it refers to some media took place around chemistry, electrochemical action or a metal compound physical effects cause damage by a phenomenon arising. Common metal bellows corrosion in accordance with the principle of points can be divided into two parts one is another electrochemical corrosion chemical corrosion. So we usually use anti-corrosion measures, what does? Usually that is externally applied coating metal hose, electrical protection and use of corrosion inhibitors. To completely eradicate corrosion of metal bellows is difficult to achieve, because the reaction between the media and the media can not all be avoided. So we can only strengthen regular maintenance, periodically review the corrosion of metal bellows, corrosion regularly disposed of. Serious corrosion and quickly found replacement to avoid accidents. Record metal bellows and what medium corrosion is more serious, less or prohibit contact with metal bellows. Corrugated tube bending resistance aesthetic choice | Hopen hose | corrugated tube bending resistance is provided by Ning County Hopen stainless steel metal hose Limited.
