Import Dn1000 Flange Rubber Expansion Joint — Buy in wholesale FOB from Supplier in China

The DN1000 flange rubber expansion joint from Beijing Zhonghaiwei Environment Engineering Co. Ltd. is a single-sphere, moulded elastomeric coupling designed for axial, lateral, and angular movement compensation in piping systems. It features a rubber body with integrated floating flanges made of zinc-plated carbon steel, rated for pressures up to 1.6 MPa. The joint accommodates movements of up to 30 mm axial compression, 15 mm lateral offset, and 12 degrees angular deflection, as per standard MX601 design. Its internal tube and external cover are available in nitrile, EPDM, or neoprene elastomers, selected based on fluid compatibility and temperature exposure.

The rubber compound complies with standard industrial resilience requirements for water, wastewater, and light industrial fluids. Typical operating temperature range is -30°C to +120°C, with short-term exposure tolerable up to 121°C. The zinc-plated flanges offer basic corrosion resistance in dry or mildly humid environments; stainless steel flanges are available as an option for aggressive media. The joint is designed to reduce turbulence and prevent material entrapment, making it suitable for systems with suspended solids or viscous fluids. It is not intended for continuous vacuum service or high-velocity steam without additional reinforcement.

This expansion joint is commonly specified in municipal water distribution, wastewater treatment plants, chemical processing lines, and industrial HVAC systems where vibration isolation and thermal expansion compensation are critical. Buyers include engineering contractors, utility operators, and plant maintenance teams sourcing for retrofit or new construction. Trade terms typically include FOB Qingdao or Shanghai, with packaging in wooden crates or palletised bundles. Minimum order quantity is not stated; buyers should confirm directly with the supplier for batch sizes and delivery schedules.
