DN300 to DN200 Concentric Slurry Rubber Expansion Joint Reducer with 150LB and Custom Flanges (600Mm)

This 600mm face-to-face concentric reducer rubber expansion joint is custom-engineered for heavy-duty slurry transport networks requiring non-standard transition mating. Transitioning from DN300 down to DN200 under a 1Mpa (10 bar) working pressure rating, this straight-tube, zero-sphere expansion bellow is optimized to eliminate flow turbulence and localized wear during high-density abrasive medium transit. Designed to connect a standard ASME 150LB line to a specialized proprietary machine casing, this versatile rubber flexible joint serves as the definitive structural dampener and alignment solution for modern mining and ore enrichment plants.

The multi-layered composite body is meticulously hand-wrapped. The interior liner features a thick, highly specialized wear-resistant rubber compound designed to survive relentless scouring from sharp ore tailings, sand grit, and hard mineral crusts under ambient temperatures. The external structural cover is synthesized from premium EPDM rubber, providing superior resistance to ozone-cracking, UV weathering, and external process fluid splattering.

Departing from traditional full-face rubber construction, this heavy-duty unit implements a precision ring face sealing (small rim) layout. A high-durability internal O-ring profile is embedded directly inside the rubber sealing lip, preventing catastrophic bellows pull-out under sudden pipe hydraulic surges or piping offsets. Outfitted with galvanized carbon steel swivel flanges, the backing rings rotate a full 360 degrees to ease bolt hole alignment on misaligned, tight-clearance equipment headers. While this DN300*200 concentric profile satisfies standard reduction schedules, our engineering center provides full custom-to-drawing fabrication. We configure specific liner thicknesses and unique non-standard flange drillings based on your CAD prints, ensuring premium B2B quality control standards and exceptionally short lead times to avoid mill stoppage penalties.
