Expansion Joints and Metal Hose Assemblies for the Steelmaking Industry

Our expansion joints are built to perform in the extreme conditions of steelmaking operations, including blast furnaces, basic oxygen furnaces (BOF), electric arc furnaces (EAF), ladle refining systems, hot gas ducting, and high-temperature process piping.  Designed with robust, heat- and corrosion-resistant materials, they support continuous operation, helping instill confidence in their durability and minimizing maintenance and unexpected shutdowns.

Our expansion joint solutions are engineered to:

  • Manage intense thermal growth and contraction in high-heat processes
  • Dampen vibration from fans, blowers, furnaces, and heavy-duty equipment
  • Relieve mechanical stress on ducting systems, piping, and critical connections
  • Handle axial, lateral, and angular movement across complex layouts
  • Resist harsh conditions, including abrasive particulates, scale, and corrosive gases
  • Enhance uptime in demanding, continuous steel production environments
  • Extend the operational life of key system components

These solutions are applied across critical steelmaking systems, including hot gas ducting, furnace exhaust systems, secondary metallurgy lines, process piping networks, and cooling water systems, demonstrating their versatility for different operational needs.

Fabric Expansion Joints

Our fabric expansion joints are purpose-built for steel plant ducting systems, providing a highly flexible solution for low-pressure air and gas flow. They are designed to handle wide ranges of movement, reduce vibration, and compensate for misalignment in systems exposed to extreme heat, dust, and chemically aggressive off-gases.

Manufactured using engineered composite layers—combining heat-resistant fabrics, thermal insulation, and protective coatings—these joints offer durability and consistent performance in demanding steelmaking environments.

They are typically installed in furnace gas paths, ventilation systems, and emission control ducting where traditional metal components cannot accommodate the required movement.

Typical applications include:

  • Off-gas ducting from EAF and BOF systems
  • Blast furnace gas and ventilation lines
  • High-temperature air and process gas ducting
  • Baghouses and dust handling systems
  • Scrubber and filtration equipment connections
  • Fan systems handling process air and exhaust gases

Rubber Expansion Joints

Our rubber expansion joints provide flexible connections for liquid piping systems in steelmaking operations, where controlling vibration, noise, and thermal movement is critical. Manufactured with multi-layer elastomer bodies reinforced by high-strength fabric, they offer a balance of flexibility, strength, and pressure performance for demanding service conditions.

These joints help isolate vibration from pumps and rotating equipment, absorb pipe movement, and reduce stress on system components such as valves, heat exchangers, and mechanical equipment. Their elastomer construction also delivers strong resistance to corrosion, making them well-suited for cooling water, process water, and plant utility systems exposed to moisture and chemical treatment.

Typical applications include

  • Cooling water and recirculation systems
  • Process and quench water lines
  • Pump inlet and discharge connections
  • Heat exchanger and cooling system connections
  • Plant utility and service water piping
  • Slurry and low-pressure fluid handling systems

PTFE Expansion Joints

Our PTFE expansion joints are engineered for highly corrosive environments in steelmaking operations, where aggressive chemicals and process fluids demand superior material performance. Featuring a polytetrafluoroethylene (PTFE) liner with reinforced structural components, these joints provide long-lasting protection for critical piping systems.

The PTFE liner offers excellent resistance to acids, caustics, and chemical attack, while external reinforcement and metallic hardware maintain strength and stability under pressure, temperature fluctuations, and movement. They effectively absorb thermal expansion, isolate vibration, and accommodate piping misalignment in demanding process conditions.

Typical applications include:

  • Acid handling and chemical dosing systems
  • Pickling lines and chemical processing circuits
  • Scrubber and emission control systems
  • Wastewater treatment and neutralization systems
  • Corrosive slurry and process fluid transfer lines
  • Cooling water systems with chemical treatment

Slip-Type Expansion Joints

Our slip-type expansion joints, also known as packed expansion joints, feature sliding, telescopic pipe sections that allow axial movement while maintaining a tight pressure boundary. They are commonly used in steelmaking facilities where long piping systems are exposed to wide temperature swings and continuous thermal growth.

Engineered for rugged service conditions, these joints help absorb linear expansion and contraction, reducing strain on piping systems and protecting connected equipment from thermal stress and movement-related fatigue.

Typical applications include:

  • High-temperature process and transfer piping
  • Utility water and service piping systems
  • Long runs between furnaces and auxiliary equipment
  • Steam and condensate lines in plant services
  • General piping systems requiring controlled axial movement
