Complex Special Shape Flanges
- Multiple geometries: Round, oval, square, and complex non-standard flange shapes according to customer design.
- High-grade materials: Available in SS304, SS316, F51, F55, and 904L for excellent strength and corrosion resistance.
- Precision machining: CNC turning and milling ensure accurate profiles, bore sizes, and bolt-hole locations for tight, repeatable fits.
- Flexible connection design: Custom drilling patterns and sealing faces to match special nozzles, valves, manifolds, or equipment interfaces.
