BellowFlex PTY LTD

Bellowflex manufactures expansion joints for industrial systems requiring movement accommodation, vibration reduction and controlled flexibility between connected equipment and structures. Expansion joints are commonly used to absorb thermal movement, equipment vibration and structural movement in piping, ducting and industrial machinery.

Our range includes fabric expansion joints, rubber expansion joints and custom expansion joint solutions manufactured to suit different operating environments and installation requirements.

Common Uses for Expansion Joints

Expansion joints are used in industrial systems where movement, vibration or thermal expansion needs to be controlled without placing stress on connected equipment or structures. They are commonly installed between fixed connection points to allow flexibility within the system during operation.

Industrial expansion joints are used throughout ducting systems, exhaust systems, process equipment, piping networks and industrial machinery. Depending on the operating environment, expansion joints can also assist with vibration isolation and movement compensation.

Industrial Expansion Joint Systems

Expansion joints are used throughout a wide range of industries including manufacturing, processing, power generation, dust extraction and industrial ventilation systems.

Common uses include:

• Ducting and exhaust systems
• • Machinery vibration isolation
• • Thermal expansion compensation
• • Flexible connections between equipment
• • High temperature industrial systems
• • Dust extraction and air handling systems

Different expansion joint configurations are selected according to movement requirements, temperature conditions and system design.

Fabric, Rubber and Metallic Expansion Joints

Fabric expansion joints are commonly used in systems requiring flexibility, lightweight construction and resistance to heat or environmental exposure. These joints are frequently used in ducting and ventilation systems where thermal movement and vibration need to be accommodated.

Bellowflex manufactures expansion joint products including Silicone Expansion Joints, PVC Expansion Joints and Rectangular Expansion Joints for industrial systems requiring flexible connection and movement control.

Rubber expansion joints are commonly used where vibration isolation, sealing and movement absorption are required within industrial equipment and piping systems.

Metal expansion joints, also referred to as metallic expansion joints, are commonly used in systems involving high pressure or specialised operating conditions where metal construction is required.

Custom Expansion Joint Manufacturing

Custom expansion joints can be manufactured to suit specific movement requirements, operating environments and installation configurations. Factors such as operating temperature, pressure, vibration, movement range and environmental exposure all influence expansion joint selection and construction.

Bellowflex manufactures industrial expansion joints to suit a range of industrial systems, with products designed according to the functional requirements and operating conditions of the equipment.

Questions About Expansion Joints

What are expansion joints used for?

Expansion joints are used to absorb movement, vibration and thermal expansion within industrial systems while helping reduce stress on connected equipment and structures.

What is the difference between fabric and rubber expansion joints?

Fabric expansion joints are generally used for thermal movement and flexible connection requirements in ducting and ventilation systems, while rubber expansion joints are commonly used for vibration isolation, sealing and flexible pipe connections.

Can expansion joints be custom manufactured?

Yes. Custom expansion joints can be manufactured to suit specific dimensions, movement requirements, operating temperatures and installation conditions.

Where are industrial expansion joints commonly used?

Industrial expansion joints are used in manufacturing, processing, ventilation, power generation, dust extraction and other industrial environments involving movement, vibration or thermal expansion.

Can expansion joints be manufactured for high temperature environments?

Yes. Certain expansion joints are manufactured using materials designed for high temperature operating environments depending on the system requirements and operating conditions.
