metallic expansion joint assembly for boiler ducting and process piping
Metallic expansion joints absorb axial, lateral, and angular movements in ducts and piping. They protect structural supports and connected equipment by compensating thermal growth and vibration.
Technical & Performance Specifications
Material: stainless or alloy metal bellows with flanged ends
Movement Range: axial/lateral/angular as specified per installation
Pressure Rating: atmospheric to low-pressure duct systems
Temperature Rating: suitable for flue gas temperatures typical of boilers
Accessories: tie rods, limit rods, and protective liners
Scope of Supply & EPC Capabilities
Supply Format: Component supply, skid-mounted, or full turnkey integration
Lead Time: Engineered-to-order based on project scope and plant requirements
Engineering: Movement calculations, pressure test data, and installation guidance
Commissioning: On-site support for alignment and leak testing
Product Description
Industrial Applications & Plant Integration
Metallic expansion joints are applied across boiler flue ducts, economizer connections, and process piping where thermal cycles induce dimensional changes. Correct selection reduces fatigue on duct supports and downstream equipment.

Frequently Asked Questions
What is the standard turndown ratio and capacity for Metallic Expansion Joint Assembly? Sizing is based on nominal diameter and expected movement; capacity aligns with duct geometry rather than flow turndown.
Do Metallic Expansion Joints meet temperature and pressure standards? Materials and welding procedures are specified with MTCs to support temperature and pressure ratings.
Do you provide turnkey installation and retrofit engineering for Metallic Expansion Joint Assembly? Installation guidance and on-site support for leak testing are available as part of project scope.
What factors dictate manufacturing lead time and pricing for Metallic Expansion Joint Assembly? Lead time depends on material selection, pressure rating, and required movement tolerances.
