This ISO2531 Ductile Iron 45/90 Degree Elbow Bend with Double Flange is engineered for superior performance in demanding water supply applications. Its core feature is the high-grade ductile iron construction, which provides exceptional tensile strength, impact resistance, and durability, far surpassing cast iron. The product strictly adheres to the ISO 2531 international standard, guaranteeing reliable pressure ratings and dimensional accuracy for seamless compatibility with existing pipeline systems.
The fitting is designed for maximum service life and safety. It typically features a robust internal cement-mortar or epoxy lining, which effectively prevents corrosion and scaling, ensuring water quality remains pure and flow efficiency is maintained. Externally, a protective coating, such as zinc or epoxy, offers superior defense against aggressive soil conditions. The integral double flanges are precision-machined to a perfect surface finish, ensuring a tight, leak-free seal when paired with standard gaskets and bolts. This design allows for quick, straightforward installation and dismantling, significantly reducing labor time and costs. The 45 and 90-degree bend options provide essential versatility for navigating complex pipeline layouts and directional changes in municipal, industrial, and commercial water networks.
The ISO2531 Ductile Iron 45/90 Degree Elbow Bend is a critical component designed for diverse pipeline systems requiring a change in direction. Its primary application is in municipal potable water supply and distribution networks, where its robust construction ensures long-term integrity under constant pressure and buried service conditions. The double flanges facilitate fast and secure bolted connections, making it ideal for installation in water treatment plants, pumping stations, and for connecting to valves and other fixtures within the system.
Beyond main water lines, this fitting is extensively used for industrial process water conveyance, firefighting pipelines, and sewage transport applications. The ductile iron material offers excellent resistance to ground movement and external loads, making it a reliable choice for unstable soil conditions. The availability of both 45 and 90-degree angles provides essential layout flexibility for navigating around obstacles and conforming to complex project specifications in urban infrastructure, commercial building projects, and large-scale industrial facilities, ensuring a efficient and leak-proof pipeline network.
Crafted for durability and performance, our ISO2531 Ductile Iron 45/90 Degree Elbow Bend is a precision-engineered pipe fitting designed to alter the direction of flow in pressurized pipeline systems. Manufactured from high-grade ductile iron, this fitting offers superior strength, exceptional impact resistance, and remarkable flexibility compared to traditional cast iron, effectively accommodating ground movements and pressure surges. It strictly conforms to the international ISO 2531 standard, ensuring reliable dimensional accuracy, pressure ratings, and compatibility with other ISO-specified components.
The fitting is engineered for longevity and optimal flow. Its interior is typically lined with a smooth, protective cement-mortar or epoxy coating that prevents corrosion, minimizes scaling, and maintains water quality and hydraulic efficiency over decades of service. The exterior is protected by a robust zinc or epoxy layer to withstand aggressive soil conditions. The integral double flanges are precision-machined to a flawless finish, guaranteeing a perfect, leak-free seal with standard gaskets and bolts. This flange design allows for rapid installation, maintenance, and system modifications, significantly reducing labor time and lifetime costs.
This versatile elbow is an indispensable component in a wide range of applications. It is ideally suited for municipal potable water distribution networks, sewage and wastewater force mains, and industrial process water systems. Available in both 45 and 90-degree configurations, it provides the essential flexibility needed to navigate complex underground layouts, circumvent obstacles, and connect seamlessly to valves, pumps, and other pipeline fixtures, making it a fundamental building block for reliable and efficient fluid transport infrastructure.
