Ductile Iron Loose Flange Fittings, manufactured in strict compliance with EN545 and ISO2531 standards, are engineered for superior performance and reliability. The key features include exceptional Pressure Resistance, confidently withstanding high operating pressures in water supply and sewage systems. The material offers outstanding Corrosion Resistance, significantly extending the service life of pipeline networks. A major advantage is their Easy Installation; as loose flanges, they simplify alignment and bolt-fastening with DI pipes, drastically reducing assembly time and labor costs. Furthermore, the high tensile strength and durability of ductile iron ensure remarkable Impact Strength, safeguarding the pipeline integrity against external stresses and water hammer effects, making them a robust and cost-effective choice for municipal and industrial applications.
These EN545 and ISO2531 compliant loose flange fittings are essential components for Potable Water Networks, ensuring safe and leak-free connections in municipal water distribution systems. They are equally critical for Sewage and Wastewater Pipelines, where their superior corrosion resistance guarantees long-term reliability in aggressive environments. A key application is in Pipeline Rehabilitation, allowing for easy connection to existing valves or fittings and facilitating quick repairs or system extensions without requiring full pipe replacement. Their versatility also makes them ideal for various Industrial Pipelines and Fire Fighting Supply Lines, providing the structural integrity needed for high-pressure services.
Our product is a high-performance Ductile Iron Loose Flange Fitting, meticulously manufactured to comply with the international EN545 and ISO2531 standards. This specific type of fitting is designed for use with Ductile Iron (DI) Pipes, serving as a crucial connection point in pipeline networks. The "loose" design signifies that the flange ring is not fixed to the pipe, offering exceptional installation flexibility. It slides over the plain end of the DI pipe and is secured using a Standardized Gasket and a set of bolts, allowing for easy alignment and disassembly for maintenance or future system modifications.
Crafted from high-grade ductile iron, the fitting inherits the material's superior mechanical properties, combining the strength of cast iron with the flexibility of steel. This results in exceptional Durability and Impact Resistance, capable of withstanding high internal pressures, external loads, and potential water hammer effects. The internal and external surfaces are typically treated with protective linings and coatings, such as cement mortar or epoxy, providing excellent Corrosion Resistance for long-term service in both potable water and aggressive sewage environments.
This loose flange fitting is engineered to ensure a perfectly sealed, robust, and reliable joint. Its design prioritizes not only performance and longevity but also significant savings in installation time and labor costs. It stands as the ideal, specification-compliant choice for constructing, extending, or repairing modern, efficient, and safe pipeline infrastructures for municipal water supply, industrial processing, and wastewater management.
