Our fabric expansion joints are engineered as flexible, multi-layer connectors for low-pressure air and gas handling systems commonly found in water and wastewater facilities. They are designed to withstand significant movement, isolate vibration, and accommodate misalignment in ducting systems operating under varying temperatures and continuous airflow.

Built using combinations of high-performance fabrics, thermal insulation layers, and chemical-resistant coatings, these joints provide dependable operation in environments exposed to moisture, corrosive gases, and process air streams. Their lightweight, flexible construction makes them well-suited for large duct systems where rigid connections are not practical.

Typical installations include aeration air systems, odor-control ducting, ventilation networks, and exhaust-air handling systems throughout treatment plants.

Typical applications include:

• Aeration blower ducting systems
• Odor control and scrubber exhaust systems
• Ventilation and air handling ducts
• Digester gas and bio-gas handling systems
• Sludge processing air systems
• Corrosion-prone exhaust and fume extraction lines

Our rubber expansion joints are built for liquid-service applications throughout water and wastewater facilities, where managing vibration, noise, and system movement is essential for reliable operation. Their flexible design makes them ideal for protecting piping systems and connected equipment in continuously operating environments.

Constructed with multiple layers of elastomer and high-strength fabric reinforcement, these joints provide the strength needed for pressure service while maintaining the flexibility required to absorb movement. This design helps isolate vibration from pumps and rotating equipment, while also compensating for thermal expansion and minor misalignment.

Engineered with corrosion-resistant materials, they perform effectively in systems that handle treated water, wastewater, and chemical solutions commonly used in treatment processes.

Typical applications include:

• Pump suction and discharge connections
• Water and wastewater process piping
• Filtration and membrane systems
• Chemical feed and dosing lines
• Cooling and utility water systems
• Sludge transfer and handling lines
• Booster stations and distribution piping

Our PTFE expansion joints are specifically suited for highly corrosive service conditions found in water and wastewater treatment facilities, particularly in chemical handling and dosing systems.
Designed to perform in harsh environments, they provide a reliable solution when standard materials are unsuitable.

Featuring a PTFE liner with reinforced backing components, these joints offer exceptional resistance to acids, chlorine, and caustic chemicals commonly used in treatment processes. The combination of chemical resistance and structural support allows them to handle pressure, movement, and vibration while maintaining system integrity.

Their flexible design helps manage thermal expansion and alignment challenges, while also protecting piping systems and connected equipment from both mechanical stress and chemical degradation.

Typical applications include:

• Chemical dosing and injection systems
• Chlorine, acid, and caustic transfer lines
• Water and wastewater treatment process piping
• Sludge conditioning and chemical feed systems
• Corrosion-prone piping in treatment facilities
• Industrial wastewater chemical handling systems

Our slip-type expansion joints, also known as packed expansion joints, use a telescoping pipe design to accommodate axial movement in piping systems while maintaining a secure pressure boundary. They are well-suited for long pipeline runs commonly found in water transmission and wastewater infrastructure, where thermal changes and ground movement can create significant stress.

Designed for rugged service conditions, these joints provide reliable movement control in buried or above-ground piping systems. Their construction allows them to accommodate linear expansion and contraction, helping reduce strain on pipes, joints, and connected equipment over long distances.

By accommodating movement and minimizing mechanical stress, slip-type expansion joints contribute to the longevity and reliability of critical water and wastewater infrastructure.

Typical applications include:

• Long-distance water transmission pipelines
• Wastewater force mains
• Buried piping systems are subject to thermal movement
• Pump station discharge lines
• Above-ground distribution and infrastructure piping

Our metal hose assemblies are widely used in water and wastewater systems where vibration, movement, and space constraints make rigid connections impractical. They provide a flexible solution for connecting equipment and piping while maintaining system reliability under continuous operation.

Manufactured from corrugated stainless steel with external braid reinforcement, these assemblies are designed to handle pressure while allowing for movement, vibration isolation, and easier alignment. Their flexibility helps protect pumps, valves, and other critical components from stress caused by system dynamics and installation challenges.

Typical applications include:

• Pump and equipment connections
• Water and wastewater process piping
• Chemical dosing and transfer systems
• Tight or constrained installation areas
• Vibration isolation for rotating equipment
