Product Introduction
Welded bellows is a kind of mechanical part made of metal sheet, with excellent sealing and elasticity, and is widely used in vacuum equipment and other occasions that require high precision and reliability. The manufacturing method is to weld the pre-punched annular diaphragm alternately along its inner and outer edges, which makes the welded bellows have high sensitivity, good linearity and small hysteresis.
Product structure composition
The welded bellows is made of many thin hollow diaphragms that are precisely welded, and these diaphragms are welded at the inner edge in concentric circles to form diaphragm pairs, and then a plurality of diaphragms are stacked together to form a corrugated segment, and finally the metal welding at both ends and the end plate is combined into a bellows group. This structure allows the bellows to adapt to external needs and reciprocate with other moving parts.
Product Advantages
1. High pressure resistance and corrosion resistance: The welded bellows are made of high-quality stainless steel or titanium alloy and other materials, which can withstand the corrosion of high pressure and corrosive media.
2. High flexibility: Because the welded bellows adopts a corrugated structure, it has good flexibility and elasticity, and can adapt to various complex actual conditions.
3. Easy to install: Welded bellows do not need to be connected and disassembled many times like traditional pipes, and the installation operation is relatively simple and convenient.

Product Use
1. Convey liquids, gases, steam and other media
Welded bellows can be used to transport liquids, gases, steam and other media in piping systems. Compared with ordinary pipelines, welded bellows are more durable, less prone to water leakage, less prone to pressure rupture and other problems, which can ensure the safe transportation of medium.
2. It is suitable for special environments such as high temperature, high pressure, low temperature, vacuum, corrosive medium, etc
Due to the special properties of the welded bellows itself, it has significant advantages in special environments such as high temperature, high pressure, low temperature, vacuum, and corrosive media. Therefore, in the chemical, pharmaceutical, food and other industries, welded bellows have been widely used.
3. For flexible connection
The wave shape of the welded bellows allows it to have a flexible connection in the piping system. When the pipe is squeezed by external force or temperature changes, the welded bellows can act as a buffer and protect the pipeline system from being easily damaged.
