In our daily life, we will always come into contact with a variety of pipes, especially metal bellows customization, and welding metal bellows, custom seals, is actually a more important sealing technology. At present, this technology has been extended to various innovative sealing technologies, such as some non-contact gas lubrication, corrosion-resistant sealing elements, high-temperature resistant sealing elements, etc. With the gradual increase in the demand for customized sealing elements for this welded metal bellows, it will become more and more important in the safety process of chemical industry and oil and gas industry, because under extreme temperature conditions, if it is desired to transport a liquid from one area to another, it becomes quite complicated. In particular, due to different factors and the characteristics of metal bellows customized products, will affect the overall sealing of the specific effect, only to understand the factors affecting the sealing effect, production and manufacturing plants to be able to choose a more appropriate metal bellows for specific construction conditions.
It is well known that the shape of the metal plates affects their degree of bending, operative length and even formation, and in nested bellows structures, all metal plates utilized in the customization of metal bellows are virtually identical. At the same time, its contour can make it nested in the process of compression, and the metal bellows can customize its contour line, which can also improve its ability to withstand relatively high pressure. The shape of the metal bellows can effectively realize an axial movement with low spring steel, etc, among them, the arc radius of the flat plate shape is optimized by the manufacturer into a span of 20% ~ 50%, which can prevent the occurrence of an oil tank. In this case, if the metal bellows can be made to customize the bottom of the kill tubing, it will expand.
For a metal bellows with a straight section to customize its heat-affected area, the reliability of welded joints is often reduced at the change of fine structure. Researchers use linear theory to analyze and know that the inclined metal bellows customized product can effectively reduce a stress at the welding place and the heat-affected area, and the stress generated in this place is often bending stress, when the inclination angle is larger, the stress will be smaller, so people often reduce the stress by adjusting the angle.
Focus on metal bellows research for more than 30 years
