Tie‑Rod Flanged Rubber Expansion Joint with Full‑Seal Construction

The double-flanged rubber expansion joint is a high-performance flexible connection component for pipelines. With its unique structural design, it has achieved a comprehensive upgrade in terms of sealing performance, pressure resistance, and anti-detachment capability. When your pipeline system has strict requirements for sealing and safety, or there are high pressure and tension risks, choosing the double-flanged structure is a very reliable and wise decision. 
Compared with the ordinary slot-type rubber expansion joint, the large flange type has the following remarkable features:
Outstanding sealing performance: Three-way sealing: The large flange structure enables it to achieve triple sealing effects of end face sealing, pipe inner diameter sealing and backside sealing. Its sealing performance is far superior to that of ordinary rubber joints, significantly reducing the risk of leakage, and is particularly suitable for high-pressure, vacuum or highly demanding sealing conditions. 
High pressure resistance: The overall structure is more stable. The flange part is integrated with the main body, capable of withstanding higher system pressure and impact resistance, and is less likely to be blown off or damaged under high pressure.
Strong anti-separation function: The flange part can be tightly clamped by the two side pipe flanges. When the pipeline experiences a huge thrust due to pressure or thermal expansion and contraction, the flange disc can effectively limit the displacement of the joint and play the role of an internal anti-separation function. In many working conditions, it can replace the"limiting anti-separation rubber joint"for use. 
Integrated structure, longer lifespan: Usually formed as a single piece through molding process, without any joint gaps. It has high structural strength and excellent fatigue resistance, resulting in a longer service life. 
Wide range of applicable media: Depending on the type of rubber (such as natural rubber, nitrile rubber, EPDM rubber, fluorine rubber, etc.), it can withstand various media including water, oil, acids, alkalis, high temperatures, and ozone
