The DN65 Flanged Double Ball Rubber Expansion Joint for Water is designed to absorb movement, vibrations, and thermal expansion in pipeline systems, providing a reliable and efficient solution for water-based systems. Ideal for applications such as sea water, drinking water, and other fluid systems, this expansion joint reduces stress on pipelines and enhances system longevity.
Material: High-grade rubber compounds (NR, EPDM, NBR, FKM) with reinforced fabric for durability
Flange Types: Available in DIN, JIS, GOST, ANSI standards
Temperature Range: -20ºC to 100ºC
Pressure Resistance: Max working pressure of 2.5 MPa
The DN65 Flanged Double Ball Rubber Expansion Joint for Water is a critical component in many industrial and municipal water systems. This expansion joint features a double ball design, which allows it to absorb axial, lateral, and angular movements, ensuring that the system operates smoothly and without interruption.
Constructed from premium rubber materials, the joint provides excellent corrosion resistance and is highly resilient to harsh environmental conditions, including extreme temperatures and exposure to chemicals. Whether you're dealing with sea water, fresh water, or oil-based systems, this expansion joint ensures that your piping system remains flexible and resistant to wear.
What makes this product standout is its ability to handle vibration and noise reduction. Its flexible structure dampens mechanical noises and vibration, leading to quieter, more stable systems. The double sphere design ensures a balanced stress distribution, reducing the likelihood of joint fatigue and extending the service life of both the joint and the connected pipeline.
