Our single sphere flexible flange rubber expansion joint is designed for industrial piping systems requiring vibration absorption, noise reduction and thermal expansion compensation. The product features high quality EPDM or NBR rubber body reinforced with multiple layers of nylon cord for superior pressure resistance.
The expansion joint comes with galvanized carbon steel flanges that provide excellent corrosion resistance. The internal structure incorporates copper plated steel wires to prevent pull-off, especially for sizes above DN100. With more than 55% rubber content and 0% recycled rubber, our product ensures longer service life up to 3 years under normal working conditions.
Key advantages include strong resistance to acids, alkalis, oils and wear. The joints are available in various sizes from DN32 to DN1000, suitable for different pressure classes including PN10, PN16 and PN25. We offer both single sphere and double sphere designs to meet various pipeline requirements.
Our manufacturing process strictly follows international standards including DIN, ANSI, GB, JIS and BSW. Each product undergoes rigorous quality control and testing to ensure reliable performance in water, air, oil and chemical applications. The working temperature range is from -20°C to 115°C.
For special requirements, we provide customization options including different lengths, materials and connection types. Our technical team can assist with product selection and system design to ensure optimal performance in your specific application.
