Single Ball Rubber Expansion Joint – Rubber Bellow Pipe Connector for HVAC, Water, Oil & Chemical
Description:
Reliable single ball rubber expansion joint designed for vibration isolation and thermal movement absorption. Widely used in water supply, HVAC, sewage, chemical, and marine pipelines.
Highlights
1.Multi-Industry Application: Designed for HVAC, water treatment, chemical, and fire protection pipelines.
2.Thermal & Pressure Compensation: Absorbs thermal expansion, pressure pulsation, and pump vibrations.
3.Global Compatibility: Flanges available in DIN, ANSI, JIS, BS, EN standards.
4.Wide Material Selection: EPDM for hot water/steam, NBR for oil, Neoprene for seawater.
5.Long-Term Reliability: Anti-aging rubber compounds for extended service life.
The Single Ball Rubber Expansion Joint, also known as a rubber bellow connector, is engineered to provide superior flexibility and vibration absorption in modern pipeline systems. Unlike rigid connections, this joint effectively reduces stress on pumps, valves, and other pipeline equipment by compensating for axial, lateral, and angular movements.
With its compact spherical design, the joint can be installed in pipelines where space is limited. It is an excellent choice for HVAC systems, water distribution networks, fire protection pipelines, marine engineering, and chemical transport lines.
The rubber body is reinforced with nylon cord and steel wire rings, ensuring high tensile strength and pressure resistance. Depending on the medium, we offer EPDM, NBR, Neoprene, and customized rubber compounds to meet different project requirements.
This expansion joint is not only a flexible connector but also a safeguard for pipeline integrity, extending the lifespan of the system and reducing maintenance costs.
Factory Showcase
Application Fields
1. HVAC Systems: Absorbs thermal expansion and vibration in chilled water and hot water pipelines.
2.Water Supply & Wastewater: Prevents stress caused by ground settlement and pipe misalignment.
3. Oil & Gas Pipelines: Resistant to fuel, oil, and petrochemical media.
4.Marine Industry: Suitable for seawater ballast, cooling, and desalination systems.
5. Fire Protection: Ensures stable water pressure in fire-fighting networks.
Installation Notes
1.Clean flange surfaces and ensure correct alignment before installation.
2.Insert bolts gradually, tightening in a crisscross sequence.
3.Avoid over-compression; leave a small gap to allow expansion.
4.For vertical pipelines, add brackets or supports to bear pipe weight.
5.Do not expose the joint to strong solvents, oils, or UV rays for long periods.
