NBR Double Sphere Rubber Expansion Joint Ansi Double Sphere Rubber Connectors

Double Sphere Rubber Connectors are flexible piping components designed with two spherical rubber bellows to provide enhanced multi-directional movement absorption (axial, lateral, and angular), vibration damping, and noise reduction in piping systems. Constructed from materials like EPDM or Neoprene rubber and reinforced with steel flanges, these connectors effectively compensate for thermal expansion, misalignment, and mechanical stresses, making them ideal for applications in HVAC, industrial pipelines, water supply, and wastewater treatment. Their dual-sphere design offers superior flexibility and stress distribution compared to single-sphere alternatives, ensuring reliable performance under varying pressures and temperatures.

Performance characteristics of Double Sphere Rubber Connectors

Double Sphere Rubber Connectors offer ultra-high performance, reliability and longevity, thus improving plant safety and the mechanical integrity of equipment. Due to the insertion of specially designed products in rigid piping systems, Joint expansion are able to:

1. Reduce mechanical noise
2. Compensate for eccentricity
3. Eliminate electrolysis between dissimilar metals

Do you know how is a Double Sphere Rubber Connectors made? Let's see with JINGNING.

It is very important to select the appropriate joint expansion, to understand the compatibility of the medium and the selected material of the joint expansion, the range of full temperature, full pressure and full vacuum, the amount of movement required, and the size between the pipe flanges. With this information, JINGNING application engineers can help determine the ideal joint expansion for any application.
