Product description

Metal expansion joint

Metal expansion joint (also called compensator) is compensating elements for thermal expansion and relative movement in pipelines, containers and machines.

The Right Metal Expansion Joint for Your Needs

For demanding pipe and ducting applications that encounter high pressures, high temperatures, and/or harsh chemicals, metal expansion joints are the safest and most dependable solution.

High pressure, high temperature media and harsh and/or corrosive chemicals demand safe, reliable, and leak-free joints between pipe or duct sections. But, because no piping or ductwork system is perfectly designed, and because movement and vibration can’t be avoided in most (if not all) applications, you need a way to accommodate for these factors without damaging your system.

That’s where our metal expansion joints come in. While they don’t offer as much flexibility as rubber or elastomer expansion joints, metal expansion joints are better suited to challenging applications and hazardous media.
