Reliable Metal Bellows Solutions for Complex Piping Movements

Metallic Expansion Joints are flexible components designed to absorb thermal expansion, vibration, and movement in piping systems. Made from stainless steel bellows, they ensure durability and high performance in demanding environments such as power plants, chemical processing, and HVAC systems. Their robust design allows them to handle extreme temperatures and pressures while maintaining system integrity and reducing stress on connected equipment.

Single expansion

METALLIC SINGLE EXPANSION JOINT

A compact and common expansion joint designed to absorb axial thermal movements in pipelines. Its simple single-bellows construction makes it one of the most widely used joint types in piping systems.
Universal expansion

METALLIC UNIVERSAL EXPANSION JOINT

A dual-bellows expansion joint designed to absorb movements in all directions. The universal configuration makes it highly effective for lateral deflections and ideal for systems with complex piping layouts.
Hinged expansion

METALLIC HINGED EXPANSION JOINT

A single-bellows expansion joint fitted with hinge mechanisms, specifically designed to absorb angular rotation in one plane while restraining pressure thrust.
Gimble expansion

METALLIC GIMBAL EXPANSION JOINT

A bellows expansion joint equipped with two pairs of hinges connected to a floating gimbal ring, designed to absorb angular movements in multiple planes while restraining pressure thrust.
Reinforced expansion

METALLIC REINFORCED EXPANSION JOINT

A heavy-duty expansion joint enhanced with reinforcing rings to withstand higher internal pressures and provide added stability compared to standard designs.
Jacketed expansion

METALLIC JACKETED EXPANSION JOINT

A specialized expansion joint featuring a double-wall construction, with an external jacket that ensures uniform heating or cooling of the media within the bellows and pipeline.
Externally Pressurized expansion

METALLIC EXTERNALLY PRESSURIZED EXPANSION JOINT

A specially engineered expansion joint where the pressure acts on the outside of the bellows, enabling very large axial movements while preventing squirm or instability.
Two Ply Testable expansion

METALLIC TWO-PLY TESTABLE EXPANSION JOINT

A safety-enhanced expansion joint featuring a two-ply bellows construction, allowing online monitoring and testing of bellows integrity for critical service applications.
Pressure Balanced expansion

METALLIC PRESSURE BALANCED EXPANSION JOINT

A specialized expansion joint that absorbs axial and lateral movements while balancing internal pressure forces, reducing load on anchors and adjacent equipment. Available in both elbow-type and in-line configurations.
Rectangular expansion

METALLIC RECTANGULAR EXPANSION JOINT

A custom-fabricated expansion joint with a rectangular or square cross-section, designed for ducts, flue gas systems, and other non-circular piping applications.
Pantographic Linkages expansion

METALLIC PANTOGRAPHIC LINKAGES EXPANSION JOINT

An advanced expansion joint system equipped with pantographic linkages that evenly distribute movement across multiple bellows, improving performance and reliability in large-scale installations.
