Expansion Joints and Metal Hose Assemblies for the Power Generation Industry

Our fabric expansion joints are flexible, multi-layer connectors designed for low-pressure air and gas ducting systems in power generation facilities. They accommodate large thermal movement, vibration, and misalignment while providing strong resistance to high temperatures and corrosive flue gases.

Constructed from layered materials such as fiberglass fabrics, high-temperature insulation, and chemical-resistant coatings, fabric expansion joints deliver reliable performance in demanding flue gas and air handling systems throughout the plant.

Installations include boiler flue gas ducting, emission control systems, turbine exhaust systems, and large process air ducts where flexibility and thermal movement absorption are critical.

Typical applications include:

• Boiler flue gas ducting
• SCR (Selective Catalytic Reduction) systems
• FGD (Flue Gas Desulfurization) systems
• Electrostatic precipitators
• Baghouses and filtration systems
• ID and FD fan connections
• Turbine exhaust ducting
• Stack and large duct expansion sections

Our rubber expansion joints are designed for liquid piping systems in power generation facilities where vibration, noise, and thermal movement must be controlled. Manufactured with reinforced elastomer construction, these joints typically feature multiple layers of synthetic rubber and high-strength fabric reinforcement to provide flexibility, pressure capability, and long service life.

The robust construction allows them to absorb pump vibration, accommodate pipe movement, and reduce mechanical stress on connected equipment such as pumps, valves, and heat exchangers. Their corrosion-resistant materials also perform well in cooling water and plant utility systems where moisture and chemical exposure are common.

Typical applications include

• Cooling water circulation systems
• Condenser water piping
• Boiler feedwater pump connections
• Plant service water systems
• Water treatment and chemical dosing lines

Our PTFE expansion joints are constructed from polytetrafluoroethylene (PTFE) with reinforced structural components designed to withstand highly corrosive chemical environments often found in power generation facilities.

The PTFE liner provides outstanding resistance to aggressive chemicals, acids, and caustic solutions, while external reinforcement and metallic hardware maintain structural strength under pressure and movement. These joints accommodate thermal expansion, vibration, and piping misalignment while protecting critical piping systems and equipment from stress and chemical attack.

Typical applications include:

• Flue gas desulfurization (FGD) chemical systems
• Acid and caustic chemical dosing lines
• Water treatment and demineralization systems
• Chemical injection and reagent piping
• Wastewater and effluent treatment systems

Our slip-type expansion joints (also known as packed expansion joints) feature telescoping pipe sections that allow controlled axial movement while maintaining a pressure-tight seal. These joints are commonly installed in high-temperature steam and condensate piping systems within power generation facilities, where long pipe runs experience significant thermal expansion.

Built for durability and long service life, slip-type joints help protect boilers, turbines, and connected piping from mechanical stress caused by temperature changes and system movement.

Typical applications include:

• Main steam distribution piping systems
• Boiler outlet and steam header connections
• Turbine steam supply and condensate return lines
• District heating and plant utility piping
• High-temperature thermal fluid piping systems

Our metal hose assemblies are commonly installed in power generation plants where high temperatures, vibration, and thermal expansion place stress on rigid piping systems.

Constructed from corrugated stainless steel with external braid reinforcement, these flexible assemblies maintain a secure pressure boundary while allowing movement within the system. Their flexibility helps protect boilers, turbines, pumps, and auxiliary equipment from vibration, thermal growth, and alignment challenges often found in complex plant piping layouts.

Typical applications include:

• Steam and condensate piping connections
• Turbine auxiliary service lines
• Pump and rotating equipment vibration isolation
• Fuel gas and burner supply systems
• Cooling water and plant utility piping
