Universal Expansion Bellow

Product Description

A Universal Expansion Bellow (also called Universal Expansion Joint) is a flexible metallic device designed to absorb large axial, lateral, and angular movements in piping systems. It consists of two bellows elements connected by a central pipe (spool), with or without tie rods, to accommodate movement in multiple directions.

Key Features

• Two bellows connected with a spool in between.

• Can handle large lateral movements compared to a single axial bellow.

• Can also absorb small axial and angular movements.

• May include tie rods to control pressure thrust and absorb external forces.

Purpose & Application

• Used when lateral movement is significant (e.g., thermal expansion of long pipelines).

• Ideal for pipelines running in two different directions or where space constraints exist.

Where Its Used

• Power plants

• Petrochemical industries

• Oil & Gas

• HVAC systems

• Steam and condensate lines

• Refineries

Advantages

• High flexibility for lateral movements.

• Can reduce the need for multiple joints.

• Absorbs multi-directional movements in one unit.
