Our fabric expansion joints are engineered for mining ducting systems, providing a highly flexible solution for low-pressure air and gas handling applications. They are designed to accommodate large movements, absorb vibration, and correct misalignment in systems exposed to elevated temperatures, dust-laden air, and abrasive process conditions.

Constructed from advanced multi-layer composites—combining heat-resistant fabrics, thermal insulation, and abrasion-resistant coatings—these joints deliver reliable performance and long service life in harsh mining environments.

They are commonly installed in ventilation systems, dust-collection ducting, and exhaust-air systems where traditional metallic components cannot effectively handle the required movement or flexibility.

Typical applications include:

• Mine ventilation and exhaust air systems
• Dust collection and baghouse ducting
• Conveyor and material transfer point ventilation
• Kiln and dryer exhaust systems
• Process air handling in mineral processing plants

Our rubber expansion joints are designed to provide flexible, vibration-absorbing connections in liquid piping systems across mining operations, where controlling movement, noise, and equipment stress is critical. Constructed with multi-layer elastomer bodies reinforced with high-strength fabric, they offer an ideal balance of flexibility, durability, and pressure performance in demanding environments.

These joints help isolate vibration from pumps and rotating equipment, accommodate thermal expansion and contraction, and reduce stress on critical components such as valves, tanks, and process equipment.
Their elastomer construction also provides strong resistance to abrasion, corrosion, and chemical exposure, making them well-suited for handling process water, slurry, and tailings systems.

Typical applications include:

• Process water and slurry piping systems
• Pump suction and discharge connections
• Tailings and de-watering lines
• Thickener and flotation circuits
• Cooling and utility water systems

Our PTFE-lined expansion joints are specifically developed for mining environments where highly aggressive chemicals and process fluids can quickly degrade conventional materials. Utilizing a chemically inert PTFE liner paired with durable reinforcement components, these joints protect piping systems while maintaining performance under tough operating conditions.

PTFE provides near-universal chemical resistance, making it ideal for handling acids, caustics, and processing reagents used throughout mineral extraction and treatment. The reinforced construction adds mechanical strength and stability, allowing the joint to perform reliably under pressure changes, temperature cycling, and continuous movement. In addition to protecting against corrosion, these joints help manage thermal expansion, dampen vibration, and compensate for piping misalignment.

Typical applications include:

• Leach circuits and chemical dosing systems
• Reagent distribution and transfer piping
• Corrosive fluid handling in process plants
• Flotation and separation processes
• Wastewater and tailings treatment systems

Our slip-type expansion joints—often referred to as packed expansion joints—are built with sliding, telescopic pipe sections that allow axial movement while maintaining a reliable pressure seal. They are well-suited for mining operations where extended piping runs experience temperature shifts, mechanical loads, and ongoing thermal expansion.

Designed for tough service environments, these joints accommodate linear movement due to expansion and contraction, reducing strain on piping systems and helping to prevent premature wear on connected equipment. Their heavy-duty construction ensures dependable operation in applications involving vibration, abrasive media, and continuous duty cycles.

Typical applications include:

• Slurry and tailings transport lines
• Process water and transfer piping
• Long-distance piping in mineral processing facilities
• Pump connections and discharge systems
• Utility lines subject to thermal variation

Our metal hose assemblies are extensively used throughout mining operations where high temperatures, vibration, and constant movement can challenge rigid piping systems. Designed for flexibility and durability, they provide dependable connections in demanding process environments.

Manufactured from corrugated stainless steel with external braid reinforcement, these assemblies maintain pressure integrity while allowing movement within the system. Their flexible construction helps absorb thermal expansion, dampen vibration, and ease installation in tight or complex layouts—helping protect pumps, equipment, and connected piping from stress and fatigue.

Typical applications include:

• Pump connections and vibrating equipment
• Slurry and process water transfer lines
• Equipment hookups in confined or hard-to-align areas
• Dust suppression and utility water systems
• Mobile and skid-mounted equipment connections
