Bellows Expansion Joint — Flexpert Bellows

A Flexible bellows is also known as expansion joint is a flexible element that absorbs movements in the pipe system.

Flexible bellows and how they work?

Flexible bellows, are also called as expansion joint, are flexible element that absorbs movements in the piping system.

These movements they absorb are defined by axial, lateral, angular and universal movements. The flexible bellows can be designed to absorb one of these movements or to absorb more of these movements combination

Axial Movements

The axial movement is a movement of the flexible bellows in the direction of the longitudinal axis. This movements can be compressive, where the bellows are shorten in length, or extensive where the bellows extends in length. In the majority of applications, the flexible bellows is deemed necessary because of the increasing temperature of the pipe system.

Lateral Movement

The lateral expansion joint is normally equipped with fixtures such as external tie rods, which allows the unit to absorb movements in all lateral direction but also absorbs the pressure thrust

Angular Movements

The angular movement is the rotation of the bellows in longitudinal axis at one end relative to other, the axis of rotation is taken at exactly the midpoint of the bellows and perpendicular to the longitudinal axis

Universal movements

The Universal Expansion Joints consist of two bellows elements joined together by a common spool piece so it is also called as Double Bellows Expansion Joint or Universal Bellows
