A stainless steel expansion joint is a flexible component used in piping systems to absorb movement caused by thermal expansion, vibration, pressure, or mechanical displacement.

It typically consists of a thin, flexible stainless-steel bellows with end connections.

Common applications

• Steam and hot-water pipelines

• HVAC and chilled-water systems

• Chemical and petrochemical plants

• Exhaust and engine systems

• Pumps and compressors

Why stainless steel?

Stainless steel provides corrosion resistance, high-temperature capability, and durability.

For example, when a long pipe heats up and expands, the expansion joint flexes to accommodate that movement instead of putting excessive stress on the pipe, welds, or equipment.
