DN32 - DN3000mm Epdm Expansion Single Ball Rubber Expansion Joint For Pipe
Single Ball Rubber Joint With Metal Flange EPDM Rubber Flexible Joint
Rubber joints are highly elastic due to the inherent properties of their rubber material. This elasticity allows them to deform under external pressure or vibration and quickly return to their original shape, reducing vibration and shock in piping systems while absorbing and dispersing energy to protect equipment.
The rubber fitting provides excellent sealing properties with a tight, long-lasting seal at joints. Its multi-layer design (inner, reinforcing, and outer layers) ensures superior sealing performance, especially important for high-pressure, high-temperature, or corrosive media applications.
Resistant to erosion and corrosion from various media including oils, chemicals, and water. Material selection can be customized for specific applications, such as oil-resistant rubber for petroleum and chemical industries.
Maintains stable performance across diverse climatic conditions, from extreme temperatures to wet or dry environments. Special formulations are available for low-temperature or high-temperature applications.
Widely used in water supply, drainage, circulating water, HVAC, fire protection, papermaking, pharmaceutical, petrochemical, shipbuilding, and various pipeline systems for pumps, compressors, and fans. Common applications include power plants, water treatment facilities, steel mills, and engineering buildings.
