Product Description
Vulcanized Double Ball Flange Rubber Expansion Joint
Our Vulcanized Double Ball Flange Rubber Expansion Joint is a high-performance pipeline connection accessory engineered for industrial fluid systems. Crafted from premium elastic rubber (NBR/EPDM optional) and reinforced with a vulcanized double-ball structure, it delivers exceptional pressure resistance (up to PN40) and flexibility-effectively absorbing axial/lateral/angular displacement caused by thermal expansion, pipeline vibration, or foundation settlement.
The integrated flange design enables quick, tool-free installation, while the vulcanized sealing structure ensures long-term leak-proof operation (suitable for water, oil, gas, and mild chemical media). Its robust construction enhances fatigue resistance, extending service life by 30% compared to single-ball alternatives.
Widely applied in water supply, HVAC, chemical, and power plant pipelines, this expansion joint supports custom sizes (DN50-DN300) and comes with ISO/CE certifications. As a factory-direct supplier, we provide strict quality testing and 2-year after-sales support, making it a reliable choice for industrial pipeline systems.
