Introduction to Double Flanged Bend
The Double Flanged Bend is a key component in ductile iron piping systems, designed to redirect the flow of water and neutral liquids in a controlled manner. This fitting, with its double flanged design, ensures a secure connection between pipes, reducing the risk of leaks and enhancing system stability. Commonly used in water distribution, wastewater management, and various industrial applications, the Double Flanged Bend is built to meet the high-performance standards outlined in EN 545 and ISO 2531, ensuring reliable operation in a wide range of settings.
Material and Durability of Double Flanged Bend
Manufactured from high-quality ductile iron or gray cast iron, the Double Flanged Bend is known for its exceptional durability and corrosion resistance. Ductile iron fittings are favored for their toughness and flexibility, thanks to their spheroidal graphite iron structure. This unique material composition enhances the fitting’s yield strength, allowing it to perform effectively under pressure in both low and high-stress environments.
The Double Flanged Bend is also available in nodular cast iron, another type of cast iron that offers superior mechanical properties, particularly in applications where strength and flexibility are crucial. The fitting is typically coated with fusion bonded epoxy to protect it from corrosion, ensuring long-lasting performance even in aggressive environments.
Standards and Pressure Ratings
The Double Flanged Bend complies with EN 545 and ISO 2531 standards, guaranteeing high-quality manufacturing and reliability in water and industrial systems. It is available in pressure ratings of PN10, PN16, and PN25, making it suitable for a wide range of pressures. These pressure ratings provide versatility, allowing the fitting to be used in both low and high-pressure applications without compromising its integrity.
