Stainless Steel Bellows Expansion Joint for Aerospace Industry

Are you confused about metal? India’s stainless steel bellow maker


The expansion joints of the stainless steel metal bellows are versatile and an essential technology that permits a wide variety of engineering applications. They are essential in controlling movement, pressure and vacuum. Many sectors use metal bellows in a variety of machine sets and parts.

SS Metal bellows can be customized to perform a wide range of engineering functions. They are flexible, spring-shaped, and precision-designed components. SS Metal bellows convert temperature, pressure and mechanical changes into linear and lateral movement. They can also be used in flexible electronic applications.

Stainless steel bellows are a large global market that is experiencing strong demand, growth and research. Because failure is not an option, the aerospace industry needs products that can withstand harsh conditions and maintain high reliability. Aerospace engineers also need support from Stainless Steel bellow manufacturers in the form of product analysis, testing, and other services. Many parts, such as metal bellows, are specifically designed for aerospace applications. All components used in military applications are also included. Metal bellows, regardless of their size, must comply with strict specifications.

Joints for Lateral and Angular Expansion


The lateral expansion joints absorb mainly lateral movement, laterally along a section pipe. They have two or more adjustable braces that can be adjusted to prevent the bellows from moving axially.


Lateral stainless-steel metal expansion joints absorb transverse as well as lateral movements. They include restraints such a ball bearing coupling rod, flat tie bar with bolts, or crossed hinges. An intermediate tube connects two angular expansion joints to form a side expansion joint. The flexure angle of a hinge arrangement and the length the intermediate pipe determine the extent of permissible lateral movement.

Articulated expansion joints are not restricted to axial or universal expansion, unlike unrestricted axial joints. They do not apply axial load created by internal pressure to adjacent pipe supports.

Universal Expansion Joints

Two bellows have multiple convolutions and are joined by a central tube. These joints are also called tandem or double bellows expansion joints. They can absorb any combination of axial and lateral movements in a pipe.

Universal expansion joints can be installed when the lateral movement is too great to accommodate one axial expansion joint, or when the connection equipment or pipe limit allows for lateral forces to be allowed.



Gimbal expansion joints


The gimbal tube extension joint is identical to the hinge type except that it can absorb the angular rotation of any plane using two pairs hinges attached to a floating cardan ring.

Cardan systems typically consist of either two gimbal expansion joints, or two gimbal joint/bellows and an articulated extension joint/bellow. This construction type has many advantages. It is able to control the movement of the bellows and can also be used with the pipe’s dead weight.

The gimbal structure also serves wind and shear loads. Gimbal bellows joints offer greater versatility because they are not limited to one plane.
