DIN Lap Joint Flange

Key Features of DIN EN 1092 Lap Joint Flange

1. Compliant with DIN EN 1092 Standards:
   • Designed and manufactured as per the European standard for flanges, ensuring compatibility with other DIN EN 1092 piping components.
2. Two-Piece Design:
   • Comprises a rotating flange and a stub end, allowing for easy alignment and assembly.
3. Rotating Flange:
   • The free rotation of the flange simplifies the alignment of bolt holes, reducing installation time and effort.
4. Material Flexibility:
   • The flange can be made of a lower-cost material, while the stub end, which contacts the fluid, is crafted from corrosion-resistant or compatible materials.
5. Ease of Maintenance:
   • Ideal for piping systems that require frequent disassembly for cleaning, inspection, or replacement.
6. Low to Moderate Pressure Applications:
   • Typically used in systems with pressure ratings such as PN6, PN10, and PN16, suitable for non-critical applications.
7. Versatile Surface Finishes:
   • Available with sealing face options such as flat face (FF) or raised face (RF) to suit different gasket types.
8. Corrosion Resistance:
   • When paired with a stainless steel or corrosion-resistant stub end, it offers excellent durability in harsh environments.
9. Standard Dimensions:
   • Features standardized dimensions for flange diameter, bolt circle, and bolt size, ensuring universal compatibility.
10. Wide Range of Materials:

• Compatible with materials such as carbon steel, stainless steel, and alloy steel to meet diverse industrial requirements.

11. Cost-Effective Solution:

• Reduces overall costs by utilizing lower-grade materials for the flange while maintaining system integrity with a high-quality stub end.
