application
- Industrial High-Pressure Systems:Process pipelines above 300 psi in petroleum refineries (ANSI 300 grade),Compressed air/steam pipeline flange conversion.
- Fire Protection and Safety Systems:Large complex fire ring pipe connections (UL/FM certified),Quick maintenance interfaces for pump room valve assemblies.
- Building Upgrades and Renovations:Expansion and renovation of existing flanged pipeline systems (no cutting or welding required),Maintenance of pipelines in narrow pipe shafts or ceilings (modular disassembly saves space).
- Special Conditions:Compressor inlets and outlets with frequent vibrations,Pipelines subject to alternating hot and cold temperatures.
advantages
- Modular innovative design: Two-piece structure supports local disassembly and maintenance, avoiding the need to replace the entire pipe section,Independent bolt fastening (carbon steel material) for convenient on-site adjustment.
- Superior sealing combination: Provides EPDM/NBR/silicone multi-material gaskets suitable for oil, high temperature, and chemical media.
- Wide pressure range coverage:Supports ANSI 125/150 (300 psi) to ANSI 300 (500 psi), covering all pressure requirements.
- Wide flange compatibility:Compatible with various flange faces such as FF/RF/MF (ANSI B16.1/B16.42 standards).
- Full-scenario corrosion protection:Dual process of red paint/hot-dip galvanizing, suitable for indoor and outdoor corrosive environments.
packing
- Component Packaging Protection:Flange plates and bolt assemblies are individually sealed in plastic, with gaskets packaged separately in anti-aging bags.
- Seismic Packaging Solution:
- ≤8″ products: Vacuum-formed inner tray + corrugated box (10 sets per box)
- ≥10″ products: Custom wooden box with bolt-fixed mounting holes (to prevent shifting during transport)
- Labeling Enhancement:
- Outer boxes marked with pressure ratings (ANSI 125/150/300) and gasket material codes
- Humidity indicator cards placed inside boxes for hot-dip galvanized products
