Factory Custom Handmade End Face Full Sealed ANSI Flange Flexible Rubber Expansion Joint
Factory Custom Handmade End Face Full sealed ANSI Flange Flexible Rubber Expansion Joint
An "end face fully sealed rubber expansion joint," also known as a "full face flange rubber expansion joint" or "large flanged flexible rubber joint," is a type of flexible connector used in piping systems.
Its key characteristic is that the rubber sealing face extends fully to the outer edge of the flange, creating a complete seal across the flange surface.
Key Features:
Full Face Seal: The rubber material of the expansion joint is molded to cover the entire flange face. This ensures a tighter, more reliable seal compared to designs where the rubber only contacts the inner part of the flange.
Integrated Design: The rubber bellow and the full face flange gasket are often designed as a single, integrated unit. This enhances the seal and prevents the rubber from being pulled away from the flange, especially under high pressure.
High Pressure Resistance: This design is particularly beneficial in applications with higher pressure requirements as the full face contact distributes the pressure more evenly across the flange.
Prevents Pull-Off: The extended rubber face provides a larger contact area, significantly reducing the risk of the expansion joint being pulled off the flange due to pressure or movement.
Flange Material Options: Flanges are typically made from carbon steel, but stainless steel (e.g., 304, 316) is also available for corrosive environments.
Rubber Material Options: Common rubber materials include EPDM, NBR, and neoprene, each offering different levels of resistance to temperature, chemicals, and other media.
Size Range: Available in a wide range of nominal diameters (DN), from smaller sizes up to very large diameters (e.g., DN4000).

Applications:
End face fully sealed rubber expansion joints are particularly well-suited for:
High-pressure pipelines: Where a reliable and robust seal is critical.
Large diameter pipelines: The full face design provides better stability and sealing for larger connections.
Applications with strict sealing requirements: To prevent leaks of potentially hazardous or valuable media.
