Global Welded Metal Bellows Market, Segmentation by Type

The Global Welded Metal Bellows Market has been segmented by Type into Stainless Steel Bellows and High Nickel Alloys.

This type is characterized by its ability to accommodate large axial movements while providing a high degree of flexibility. Axial welded metal bellows are commonly used in applications requiring expansion or contraction along a single axis, such as in pipelines, exhaust systems, and aerospace components. Their design helps in absorbing thermal expansions and contractions, reducing the risk of damage to connected components.

Designed to handle movements perpendicular to the axis, lateral welded metal bellows are crucial in applications where there are lateral displacements or vibrations. These bellows are typically used in industrial machinery and automotive systems to manage the stress and strain caused by lateral movements. Their construction ensures durability and reliability in environments where lateral flexibility is needed.

Offering flexibility in both axial and lateral directions, universal welded metal bellows are ideal for applications that require multi-directional movement. They are often used in complex systems such as aerospace and high-performance industrial machinery where movement in multiple directions needs to be accommodated. The versatility of universal bellows makes them suitable for dynamic and demanding environments.

These bellows feature an additional tie rod or restraint system to limit the extent of movement and ensure stability. Tied welded metal bellows are used in applications where controlled movement is required, such as in high-pressure systems or critical components where precise control over expansion and contraction is necessary. The tie rods help in maintaining alignment and preventing excessive movement that could lead to mechanical failure.
