DN50 90-Degree EPDM Rubber Expansion Joint Elbow with Molded Bellow and Polypropylene Flanges (1Mpa)

This DN50 (2-inch) 90-degree molded rubber expansion joint elbow is precision-engineered for aggressive chemical process piping where compact directional change and premium corrosion isolation are required simultaneously. Operating under a 1Mpa (10 bar) pressure rating, this molded EPDM rubber bellow absorbs intense high-frequency vibrations and accommodates multi-directional mechanical stresses without restricting fluid movement. Outfitted with heavy-duty white Polypropylene (PP) backing flanges, this specialized rubber flexible joint completely eliminates galvanic corrosion risk and minimizes structural load on fragile thermoplastic or glass-lined piping headers.

The vulcanized structural body is precision-molded to guarantee absolute uniform wall thickness and zero micro-porosity. Synthesized from ultra-high purity EPDM rubber, the flexible compound delivers exceptional resistance to inorganic acids, alkaline solutions, oxidizing agents, and aggressive process wastewater at typical ambient to elevated temperatures. Unlike traditional heavy metallic backing rings, the chemically inert PP flanges provide perfect chemical compatibility for washdown zones, corrosive sub-floor trenches, and chemical dosing skids.

This compact 90° rubber bellow incorporates a fully integrated raised sealing lip profile that ensures tight, leak-free performance without requiring external gaskets. The independent PP swivel flanges rotate a full 360 degrees to eliminate bolt-hole misalignment stress during critical field retrofits, preventing any residual stress transmission to the adjacent plastic pipe network.
