What Are Expansion Joints?

Expansion Joints are designed to safely absorb the movement in pipework systems due to heat-induced expansion and contraction of pipework.

Expansion Joints applications

An expansion joint is a useful component in an infinite number of applications.

Pipe expansion joints are necessary in systems that convey high temperature commodities such as steam or exhaust gases, or to absorb movement and vibration. A typical type of expansion joint for pipe systems is a bellows which can be manufactured from metal (most commonly stainless steel), plastic (such as PTFE), or an elastomer such as rubber.

A bellows is made up of a series of one or more convolutions, with the shape of the convolution designed to withstand the internal pressures of the pipe, but flexible enough to accept the axial, lateral, and/or angular deflections. Expansion joints are also designed for other criteria, such as noise absorption, anti-vibration, earthquake movement, and building settlement.

An expansion joint is a useful component in an infinite number of applications. Metal expansion joint assemblies are commonly used for all kinds of industries and applications including:

  • Power Generation
  • Co-Generation, Petrochemical
  • Chemical Processing
  • Pulp Paper Manufacturing
  • Cryogenic Process
  • Pressure Vessel and heat Exchanger Fabricators
  • Heat Steam recovery Generator
  • Architect Engineering
  • Construction Engineering
  • Mechanical contractor
  • Pharmaceutical manufacturing
  • Gas Turbine, Gas Transmission
  • Ship building and Repair
  • Diesel Engine Mfg, Incineration
  • Waste Water Treatment
  • Metal Smelters
  • Pollution Control
