Universal Expansion Bellow

About Universal Expansion Bellow

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 eg 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 multidirectional movements in one unit
