Ductile Cast Iron DI 90 Degree Double Flanged Duckfoot Bend DN100 PN16
The ductile iron right-angle 90-degree double-flange duckfoot elbow is a common pipe fitting. The following describes it from three perspectives:
Material Characteristics
Ductile iron: This material is made from ordinary cast iron through a process of spheroidizing and inoculating to produce spheroidal graphite. Compared to ordinary cast iron, ductile iron offers higher strength, toughness, and ductility, greater resistance to shock and vibration, and the ability to withstand high pressure, making it suitable for a variety of complex engineering environments.
Structural Features
Right-angle 90-degree: This elbow features a standard 90-degree bend, used to change the flow direction of fluids (such as water and gas) in a pipe, allowing for flexible piping system layout according to design requirements.
Double-flange: The elbow features flanges at both ends, which are bolted to other flanged pipes, valves, or equipment. This connection method is easy to install and remove, and offers excellent sealing properties, effectively preventing fluid leakage.
Duck foot : This typically refers to an elbow with a support structure similar to a duck's foot. The support typically has bolt holes and can be fixed to the foundation using anchor bolts, providing stable support for the elbow. This effectively disperses the forces generated by the fluid pressure within the pipeline and the weight of the elbow, enhancing the stability of the piping system and reducing the impact of vibration, stress, and other factors on the pipe connection.
Applications
Water Supply and Drainage Engineering: In urban water supply and drainage systems, it is used at pipe bends to ensure smooth water flow while also withstanding a certain level of water pressure.
Industrial Piping Systems: Industrial pipelines in industries such as petroleum, chemical, and power transmission convey a variety of high-temperature, high-pressure, and corrosive media. Ductile iron right-angle, 90-degree, double-flange duckfoot elbows, with their excellent performance, ensure safe and stable operation of the piping system.
Fire Protection Systems: As a connector for fire protection pipes, it meets the requirements for rapid and stable firefighting water delivery, ensuring the proper functioning of the fire suppression system in the event of a fire.
