Defects of stainless steel welded metal bellows welding metal bellows due to defects, the tensile stress concentration or stress, compared to other places for fatigue strength will be significantly lower than normal. Therefore, depending on the performance of welded joints in the entire structure, it was decided whether the normal safe operation. So metal bellows manufacturers in order to ensure the reliability of the structure, stainless steel bellows structure designed to withstand the pressure of time, usually by welding points as the life of the entire system, rather than a simple calculation of the strength of the metal, so this caused a lot of waste. While such measures, but under the pressure of local joints, the situation is still premature failure can occur. In order to enable a good use of effects must be taken to meet the new measures. 1. Increase the understanding of the fatigue resistance of stainless steel metal bellows, and the design of new construction makes the whole system more reasonable, to ensure and improve the quality of produce textile welding defects. 2. Using flanging free solder structure, which can greatly improve the life without soldering, because to avoid direct contact with corrosive media, flange steel flange can also be used effectively to reduce costs. Stainless steel metal bellows under pressure in recent years to increasingly high demand, so the improvement is very urgent new technologies, as opposed to overseas development using high-tech welding, meaning domestic manufacturers to improve the process of far-reaching, but also research and development of future direction. Stainless steel corrugated metal hose industry cohabitation stainless steel bellows manufacturers cohabitation, some shoddy work is very common, and even the use of stainless steel iron is used as a material, is the so-called stainless iron scrap, steel scrap and other recycled materials produced by the method of writing a column treatment is made. Because after the demagnetization process, so the method can not be detected with the entry into force of the magnet, so it can deceive, since thick media report found that accounted for about 65 percent of the manufacture of automotive bellows, while the real price is too high due to lack much of stainless steel cold. Iron is not easy to rust stainless iron, stainless steel iron corrosion resistance is due to the oxide film formed on the surface of the formation of this corrosion resistance is relative, because the use of the car bellows can not use long time in different environments which there are many classifications stainless iron, according to the organizational structure of classification, martensitic, austenitic, etc., if classified according to chemical composition, can be divided into chromium and chromium-nickel-containing, if it is in accordance with the use classification there seawater resistant, resistant to nitric acid. Because stainless iron affordable, compatibility and corrosion resistance so in heavy industry, light industry has widely used, but if used on stainless steel bellows very unsuitable, because corrugated compensation to withstand the test of time environment must be able to work the car stable bellows, iron and stainless certainly not have such well-known manufacturers the ability to auto bellows, otherwise it would not be so cheap, so manufacturers cut corners harm the interests of consumers. Stainless steel bellows or to choose reputable manufacturers, must not yield to the temptation to buy cheap cheap products, we must shop around, stable product is more important than price.
