application
- Industrial pipeline terminal connections: Necked threaded flanges for deformation-resistant sealing connections between equipment and pipelines .
- Fire protection system expansion: UL-certified structures for high-pressure flange connections between sprinkler networks and pump valves .
- Ship propulsion systems: Anti-vibration flange solutions for engine room fuel/cooling water pipelines and equipment.
- Energy Transmission Networks: Sealed flange connections for oil and gas pipeline metering devices.
- Chemical Process Equipment: Corrosion-resistant flange interfaces for reactor inlet/outlet pipelines.
- Municipal Pipeline Network Renovation: Long-term sealed connections between main road valve assemblies and pipelines.
- Mining Equipment Integration: Anti-loosening flange solutions for pumps and pipelines in high-vibration conditions.
- Agricultural Irrigation Hubs: Flange connections between pump station high-pressure pipelines and filtration equipment.
advantages
- Reinforced structural design: Neck reinforcement ribs enhance the flange’s resistance to bending stress.
- Dual sealing protection: BSPT threads + flange sealing surface (FF/RF type) provide dual leak prevention.
- Easy installation: Threaded connections eliminate welding procedures, reducing installation complexity.
- Standard compatibility: Flange surfaces comply with EN1092 standards, compatible with PN16 carbon steel/copper alloy flanges.
- Long-Term Corrosion Protection System: Hot-dip galvanized coating certified by ISO 9227 salt spray test.
- Pressure Compatibility: PN16 rating meets industrial pipeline system pressure requirements.
- Optimized Bolt Hole Design: DN65 specification offers a 4-hole design option.
- Full Size Range Coverage: DN32-DN100 meets mainstream industrial pipeline requirements.
packing
- Sealing surface protection: the flange seal surface is covered with PE film.
- Protection of bolt holes: Engineering plastic plugs for the sealing of bolt holes in order to avoid yielding of damage.
- Heavy Transport SolutionMaterial: Steel-reinforced fumigated wooden box (complies with ISPM 15).
- Traceability management system: box QR code connected to material reports and standard certifications.
- Design with anti-deformation: Internal support frame that keeps the flange flat .
