Concentric reducing flange type rubber expansion joint
DN80*DN100
The Concentric Reducing Flange Type Rubber Expansion Joint is a versatile, high-performance flexible connector designed to seamlessly join pipes of different diameters while effectively absorbing vibration, reducing noise, and compensating for thermal expansion and contraction in piping systems. Unlike traditional metal reducers, this all-rubber joint offers superior flexibility and durability. Engineered with a robust construction of high-strength synthetic rubber and fabric reinforcement, it provides excellent compensation capabilities and effectively reduces tensile stress between connected pipelines. Its concentric design not only streamlines fluid flow but also saves valuable installation space and reduces overall system costs.

Key Features and Benefits
This expansion joint enables efficient pipe size transition by allowing simple, direct connection between pipes of differing sizes, functioning as both a flexible joint and a pipe reducer or increaser. It delivers superior vibration and noise dampening, effectively isolating vibration and dampening noise generated by pumps, compressors, and other rotating equipment, thereby protecting sensitive system components. The joint is capable of multi-directional movement absorption, including axial compression and extension as well as lateral and angular displacements, accommodating pipeline misalignment and thermal expansion. The integral flanged design eliminates the need for separate gaskets, simplifying installation and ensuring a reliable seal. Additionally, it offers excellent corrosion and abrasion resistance, being manufactured from a selection of elastomers such as EPDM, NBR, and Neoprene that are resistant to corrosion, abrasion, and a wide range of process fluids, ensuring long service life.
Technical Parameters
The product is available with integral flanges and loose backing flanges in materials including carbon steel, stainless steel, or aluminum. It conforms to applicable standards such as ASME, ANSI, DIN, BS, and JIS. Elastomer options include EPDM, NBR, Neoprene, Natural Rubber, and Viton. The pressure rating can reach up to 16 bar depending on size, while the temperature range spans from -20°C to +115°C, with special compounds available for temperatures up to +250°C. The diameter range covers from DN25 to DN3000 and above, with custom sizes available upon request.
Application Scenarios
This expansion joint is the ideal solution for flexible pump connectors and equipment connections where a change in pipe size is required. By combining the functions of a pipe reducer and an expansion joint, it simplifies piping layouts and reduces the number of components needed. Its flexible elastomer body effectively isolates vibration from the pump, eliminates electrolysis, reduces stress on the piping system, and protects against damaging start-up surges. This not only extends the life of your equipment but also minimizes noise, creating a quieter and more efficient working environment.
Important Engineering Note
When using concentric reducing expansion joints, it is critical to anchor the piping system properly, especially in larger diameters. Standard control rods may not be suitable for these joints, as the smaller end can create a lever effect, requiring specially designed control units to ensure safe and reliable operation. For optimal performance and longevity, proper selection of elastomer material and flange rating based on the specific service conditions is strongly recommended.
