Taking care to maintain the benefits of metal bellows are generally two plane buckling instability is instability and cylinder. Wavenumber bellows center allowed too much or are likely to be one of the causes of instability. Plane instability is due to the effect of the internal pressure and circumferential forces generated under the stress of the film so that the metal bellows produced damaging deformation, the plane is due to instability caused in a compressed state. In either case resulting destabilization, if not controlled, resistant to bending corrugated pipes, pressure focused on some of the wave, then eventually it will cause metal bellows fatigue fracture, or even burst, or worse will happen property life damage. If unreasonable design can also cause instability of the situation, such as the use of unreasonable material, if there is no basis for the use and design of the customer's initial production, chose the wrong material is also an important cause of the damage. Welding and assembly of links is also a priority, due to faulty welding and assembly lead to component damage or uneven force are also common situation. Metal bellows delivered to customers in the hands of the final part of the installation can not be ignored, such as stents strength of non-compliance or pipeline center asymmetric metal bellows distorted, curved resistant bellows authentic guarantee, not in accordance with the requirements of these small details will be stretched reduced service life. If you want to spend less to raise the price of life, we must adopt the right measures and maintenance. Welded Metal Bellows of stainless steel weld metal bellows due to defects, stress concentration or tensile 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 pressure, generally it is based on the life of solder joints as the entire system, excellent resistance to bending corrugated pipe manufacturers, rather than simply The 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 is necessary to meet the new measures. 1. Increase the understanding of fatigue stainless steel metal bellows, the design of new structure of the whole system more reasonable, resistance to bending-type bellows best quality, guarantee 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 the corrosive medium, flange steel flange can also be used to reduce costs. Stainless steel metal bellows under pressure in recent years to increasingly high demand, therefore very urgent to improve the new technology, with respect to the overseas development using high-tech welding, meaning domestic manufacturers to improve the process of far-reaching, but also research and development of future direction.
