Large Size Single Floating Flanged Rubber Expansion joint Connector

Key Features
The connector is constructed with a high-quality rubber body, typically made from EPDM, NBR, neoprene, or natural rubber, selected according to the specific media and working environment. The single floating flange design enables rotational adjustment during installation, which greatly simplifies the alignment of bolt holes and reduces installation time and labor costs. The flanged ends comply with international standards such as DIN, ANSI, JIS, or BS, ensuring compatibility with a wide range of pipe systems.
The large size construction makes this product suitable for pipelines with nominal diameters typically ranging from DN300 to DN3000 or even larger, depending on customer requirements. The reinforced synthetic fiber cord and steel wire ring embedded in the rubber body provide excellent pressure resistance and dimensional stability, allowing the joint to withstand high working pressures while maintaining flexibility.
Performance Advantages
This expansion joint offers excellent resistance to aging, ozone, UV radiation, and a wide range of chemicals. It effectively compensates for axial compression, axial extension, lateral displacement, and angular deflection, thereby protecting pumps, valves, and other equipment from stress and damage caused by pipe movement. The floating flange design also reduces the risk of leakage by ensuring uniform gasket compression around the entire flange face.
The product operates efficiently across a broad temperature range, typically from -20°C to 115°C depending on the rubber material chosen, with special compounds available for higher or lower temperature applications. It is also available with optional accessories such as control rods, limit rods, and vacuum support rings to meet specific installation and operational requirements.
Applications
The Large Size Single Floating Flanged Rubber Expansion Joint Connector is widely used in water treatment plants, desalination facilities, power generation stations, chemical processing plants, oil and gas pipelines, HVAC systems, marine and offshore engineering, and other heavy industrial fields. It is particularly suitable for large-diameter pipelines where thermal expansion, vibration isolation, and misalignment compensation are critical concerns.
Installation and Maintenance
Installation is straightforward due to the floating flange design, which allows the flange to rotate freely for easy bolt hole alignment. It is recommended to install the expansion joint in a neutral position and avoid excessive compression or extension during installation. Regular inspection for signs of wear, cracking, or leakage is advised to ensure long-term reliable performance. The product requires minimal maintenance and offers a long service life when properly installed and operated within specified conditions.
Quality Assurance
Each unit is manufactured under strict quality control procedures and can be tested for pressure, leakage, and material properties before delivery. Custom sizes, materials, and flange standards are available upon request to meet specific project requirements.
