The Expansion bellows are installed to alleviate the pipe movement owing to thermal expansion or the machine vibrations that are transmitted through the pipeline. They allow axial or lateral movement of the pipe or compression/ relaxing of the pipeline. They are usually installed in long runs of pipeline or near machinery that will transmit vibration through the pipeline

What piping expansion bellows ?
Piping expansion joint or Expansion bellows containing one or more metal /rubber bellows.
Piping Expansion Joint are used to absorb dimensional changes caused by thermal expansion or
contraction of pipeline, duct or vessel while containg the system pressure
The Flexible element of the expansion joint that expands or contracts to absorb the thermal
movement is called as bellows
Piping Expansion joint are used in the piping systemto absorb the thermal expansion or
terminal movement where the use of Expansion loops is impractical
Expansion joints are used in piping systems to absorb thermal expansion or terminal
movement where the use of expansion loops is undesirable or impractical.

Meta Description
A Flexible bellows is also known as expansion joint is a flexible element that absorbs
movements in the pipe system.
Content
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
Our Product Range can be seen here: Flexible bellows range
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
4. 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

Expansion Piping
What is Expansion Piping?
The Expansion Piping or vent pipe is a pipe associated with the cold water storage cistern or
feed an expansion cistern. Its purpose is to accommodate the expansion piping of water when
it is heated, and allow passing the excess water to vent harmlessly into the cistern.
What is Expansion Piping?
An Expansion piping joint is installed in piping systems for couple of reasons. Not only can they
be used absorbed the vibration and shock they can be relieve the anchor stress, reduce noise
and compensate for misalignment. Certain Piping Expansion Joint are also designed for thermal
expansion in very hot applications
Expansion Joints allows pipe to move in three different ways;
Axial compression or extension
Lateral off set
Angular deflection
6. They typically come in three different materials to provide the range of applications
Metal
Metal expansion is commonly used in application where thermal expansion is an issue. When
the temperature of the pipe increases, the metal expansion joint compresses to compensate
for the movement, taking stress off the anchors and the pipe. Meat expansion is a live example
of how to handle expansion hot pipes.
Rubber
Rubber can be used for thermal expansion, and it also absorbs the vibration and shock waves
extremely well. That’s why this type of expansion joint is great for minimizing the transmission
noise, Vibration from other equipment to protect equipment like pumps
Braided
The braided stainless hoses with the flexible or metal liners aren’t technically an expansion
joint, more of a flexible connector. They work well in high pressure and temperature of
applications requiring the vibration dampening or pipe misalignments
Advantages of Bellows
To Increase the range of high pressure that the bellows can measure and to protect it from the
strain, the bellows is pre compressed and fitted into a bellows unit
It is used to measure absolute and differential pressure
It is used to measure low or medium pressure range
