Rubber Expansion Joint

Introduction to Rubber Expansion Joint

This type of bellows protects equipment’s and piping from damage caused by vibration and thermal movements and accommodate equipment misalignments. It provides superior flexibility, movement absorption, and cycle life, while resisting chemical attack and abrasion. It is useful over a wide range of temperatures & pressures, making them the preferred expansion joint for most liquid and slurry applications, though gases & solids are also frequently conveyed by rubber expansion joints.

Applications of Rubber Expansion Joint:

  • Oil and Gas
  • Power
  • Steel
  • Chemical and Fertilizer
  • Cement
  • Defence and Railways
  • Water

Features of Rubber Expansion Joint

 Rubber Expansion Joint
Made from natural or synthetic rubbers,
Provides better flexibility with less spring force
Absorbs vibrations as well as reduce noise
Used for axial, lateral and angular movements
Used for transporting fluids, slurries, water, waste and gases at elevated pressure

Design and Installation of Rubber Expansion Joint

There are several parameters required to design a Rubber Expansion Joint:

  • Internal Diameter
  • Design Pressure
  • Material of Bellows Element
  • Design Temperature
