Stainless steel flexible metal steam expansion bellows ss 316 joint
As a kind of flexible pressure pipe fittings, expansion bellows are installed in the liquid conveying system to compensate the mutual displacement of pipeline, machine and equipment. expansion bellows absorbs vibration energy and can play the role of vibration reduction and silencing. The pitch of expansion bellows is flexible and has good scalability, without blocking and stiffness; The expansion bellows can be freely bent into various angles and radius of curvature, and has the same softness and durability in all directions.

Expansion bellows application
Due to the limited flexibility of the metal bellows joint, the metal bellows joint can compensate the temperature difference deformation or other deformation between the equipment and the pipeline, prevent vibration, reduce the thrust of the pipeline on the equipment, and adapt to the uneven settlement of the oil tank foundation. Expansion bellows can be widely used in chemical industry, oil refining, electric power, light industry, atomic energy, metallurgy, machinery, instrumentation, shipbuilding, aerospace and other departments. With the wide application of power pipeline and heat pipeline in industrial and civil fields, the requirements for expansion bellows are higher and higher.
