Manufacturing Expansion Joints and Bellows in India
What is Expansion Joint?
An Expansion Joint is a device containing one or more metal bellows used to absorb the dimensional changes such as those caused by the thermal expansion or contraction of a pipeline, duct, or vessel
What is the use of Expansion joints and bellows?
Expansion Joints and Bellows are used in the Piping System.
They are made of add like flow liners, covers, and tie rods. The metal bellows act like springs but they are restricted to contain the pressure of the fluid that flows through the expansion joint.
A proper flow depends much on the movement of the connected piping.
If Expansion Joints are removed from the piping system, high stress would be created by the thermal expansion.
This can cause massive pressure resulting in the cracks of the welds and bending of the pipes.
The corrugations are designed in such a way that they can tolerate the massive pressure of the entire system.
The assembly of the bellows is placed in such a way that it can flux under the thermal movement of the connected piping.

How do Expansion joints work?
An Expansion Joint or movement joint is an assembly designed to hold the parts together while safely absorbing the temperature-induced expansion and contraction of building materials, and vibration, or to allow the movement due to ground settlement.
