DN150 6 Inch PTFE Lined Single Sphere Rubber Expansion Joint PN16 with Control Rods Anti Corrosion Flexible Bellows

DN150 6 Inch PTFE Lined Single Sphere Rubber Expansion Joint with Control Rods

The DN150 (6 inch) single sphere rubber expansion joint is a premium flexible pipe connector engineered for corrosive chemical media, HVAC systems, and industrial piping. Available with PTFE (Teflon) inner lining for superior chemical resistance and integrated control rods for overstretch protection in high-pressure applications.

Key Features & Advantages

• PTFE Lining Available: Full-contact Teflon inner lining shields the rubber body from aggressive acids, alkalis, and solvents. Extends service life in chemical processing and wastewater treatment applications.
• Integrated Control Rods: Threaded steel tie rods with limit nuts prevent over-extension during pressure surges. Essential for unanchored piping and high-pressure systems.
• Superior Anti-Corrosion Performance: Available with stainless steel SS304/SS316 flanges and hot-dip galvanized coating. Combined with PTFE lining for complete corrosion protection in harsh environments.
• Dual Connection Options: Standard flanged ends per DIN/ANSI/JIS standards. Threaded (screwed) connection available for smaller sizes.
• 1.5x Test Pressure Certified: Every unit undergoes hydrostatic pressure testing at 1.5 times rated working pressure (PN16 tested at 24 bar). Test reports available upon request.
• Multi-Directional Movement: Compensates for axial compression/elongation, lateral offset, and angular deflection simultaneously.
• Wide Media Compatibility: EPDM / NBR / NR / Neoprene elastomer options for water, seawater, hot water, oil, weak acid, alkali, and chemical media.
