Flange threaded DN50 Margo KOŁ.GW050-2-OC PN10-16 EN1092-1, galvanized, certified 3.1

Threaded flange DN50 from Margo, model KOŁ.GW050-2-OC, manufactured to the EN1092-1 standard and rated for PN10–16 applications. The flange features a galvanized finish for increased corrosion resistance and is supplied with a 3.1 material certificate that documents material traceability and batch test results. It is intended for creating secure threaded connections between pipes and components in water, heating and general utility installations that require standardized EN1092-1 flanges and certified materials.

Advantages

The galvanized surface provides durable protection against corrosion in wet and humid environments, extending service life compared with uncoated components. Conformance to EN1092-1 ensures dimensional compatibility with other flanges built to the same standard, facilitating straightforward assembly and replacement. The included 3.1 material certificate gives documented assurance of material composition and mechanical properties, supporting quality control and regulatory compliance in installation projects.

Suitable for

• Joining threaded DN50 pipe connections in potable water systems
• Connections in heating and radiator circuits
• Utility and industrial installations requiring standardized flange connections
• Replacement or retrofitting where EN1092-1 compatibility is needed

Key specifications

• Nominal diameter: DN50
• Design standard: EN1092-1
• Pressure rating: PN10–16
• Connection type: threaded flange
• Surface finish: galvanized
• Supplied with: 3.1 material certificate

How to use

Inspect the flange and mating threads for damage or debris before installation. Ensure the mating threaded pipe or fitting matches the DN50 threaded size and thread type. Apply appropriate thread sealant or tape compatible with the media and system temperature, then hand-start the connection and tighten to the torque recommended for the thread specification and material. Verify flange alignment and bolt circle compatibility with mating EN1092-1 components, and perform leak testing after assembly according to site procedures.

Usage recommendations

Store the galvanized flange in a dry, ventilated area to avoid prolonged exposure to aggressive chemicals or environments that could compromise the coating. Use appropriate thread sealants rated for the system media, and follow local codes for pressure testing and installation. Retain the 3.1 material certificate with project documentation for traceability and inspection.
