application
- Energy and Industrial Systems:Offshore wind farm hydraulic piping (PN25 pressure rating 500 psi),Chemical plant PN16 acid-alkali medium transfer system.
- Municipal Critical Infrastructure:EU-certified fire protection piping network (UL/FM dual certification),Regional heating station flange interface retrofit (split-type quick-change design).
- Precision Industrial Applications:Pharmaceutical plant GMP pipeline maintenance (partial disassembly to prevent system contamination),Food and beverage production line sanitary connections (silicone gaskets with non-toxic certification).
- Special Maintenance Requirements:Tunnel/underground utility tunnel confined space operations,Ship engine room pipeline emergency repairs.
advantages
- European Standard Split Innovation:Two-piece structure supports single-side maintenance, reducing system downtime costs,Metric bolts (M10/M12) precisely match EN standard flanges.
- Type Smart Pressure Adaptation:PN16 across all sizes (1.5”-14”), PN25 catering to high-pressure pipe sections (4”-6”)
- Sealing Scenario Customizing: EPDM/NBR/Silicon 3 stage sealing option for -40°C to 150°C operation
- Full European Compatibility: Flange ends are EN 1092-2 and can be used with FF/RF/MF interfaces.
- Long-Term Corrosion Protection: o Hot-dip galvanized coating ≥80μm (suitable for marine environments), RAL 3000 red paint for indoor protection.
packing
- Modular packaging:Flange plates/bolt assemblies/gasket independent sealing units (moisture-proof and impact-resistant)
- Graded protection plan:
- PN16 products: EPE pearl cotton partitions + corrugated boxes (12 sets/box)
- PN25 products: Steel-reinforced wooden boxes (with embedded bolt positioning molds)
- European standard traceability markings:
- Outer boxes printed with EN 1092-2 standard number and pressure rating (PN16/PN25)
- Copies of salt spray test reports for hot-dip galvanized components
