Double Loose Flange 90° Duckfoot Bend


Understanding the Double Loose Flange 90° Duckfoot Bend


The Double Loose Flange 90° Duckfoot Bend is a precision-engineered piping fitting designed to redirect fluid flow at a 90-degree angle. Its unique duckfoot shape optimizes fluid dynamics, while the double loose flange connection balances stability and installation flexibility. Unlike conventional elbows, this bend minimizes flow resistance and pressure loss, making it ideal for systems where efficiency and reliability are paramount. It serves as a critical component in piping networks that require sharp, smooth turns without compromising performance.


Core Advantages of the Double Loose Flange 90° Duckfoot Bend


Smooth Fluid Flow with Duckfoot Design

The duckfoot shape is engineered to reduce turbulence and eddy currents, allowing fluids to flow seamlessly through the 90-degree turn. This design minimizes pressure drop, energy consumption, and wear on the pipeline, enhancing overall system efficiency.


Exceptional Corrosion Protection

Featuring FBE internal lining and external coating, the Double Loose Flange 90° Duckfoot Bend resists corrosion, rust, and chemical damage. The FBE coating is applied using a fusion process that ensures uniform coverage, even in the bend’s curved areas, providing long-lasting protection in wet, underground, or chemically exposed environments.


Easy Alignment and Stress-Free Installation

The double loose flange design allows for independent movement of each flange, simplifying alignment during installation. This flexibility accommodates minor deviations in pipeline layout, reducing stress on the bend and adjacent pipes. It eliminates the need for forceful adjustments, which can cause damage or leaks.


Typical Uses of the Double Loose Flange 90° Duckfoot Bend


Municipal Water Transmission Lines

In city water supply networks, the bend redirects water flow around obstacles, through tight spaces, or between pipeline sections. Its smooth flow design maintains water pressure, ensuring consistent delivery to homes, businesses, and public facilities.

For sewage treatment plants and stormwater drainage networks, the bend withstands the corrosive nature of waste fluids. Its duckfoot design prevents debris buildup, reducing clogs and maintaining efficient flow in drainage lines.


Agricultural Irrigation Systems

In agricultural irrigation, the bend adapts to field layouts, redirecting water to different crop areas. Its corrosion resistance and durable construction withstand outdoor conditions, including UV exposure and soil moisture, ensuring reliable performance season after season.


Design Specifications of the Double Loose Flange 90° Duckfoot Bend


Compliance with ISO2531/EN545 Standards

The bend is manufactured to meet ISO2531/EN545 standards, ensuring precise 90-degree angles, consistent dimensions, and compatibility with standard piping components. This adherence guarantees interchangeability and reliability across global projects.


FBE Coating for All-Around Durability

The internal and external FBE coating provides a tough, abrasion-resistant barrier against corrosion and environmental damage. The coating bonds permanently to the bend’s surface, resisting chipping, peeling, and degradation over time.


Structural Integrity for High-Pressure Applications

Engineered to handle standard pressure ratings, the bend’s robust construction and double loose flange design distribute pressure evenly, preventing deformation or failure under operational stress. The duckfoot shape reinforces the bend’s structural strength, ensuring stability in high-flow systems.


FAQ


Does the duckfoot design affect flow rate compared to standard elbows?

No—instead, the duckfoot shape improves flow rate by reducing turbulence and pressure loss. Unlike sharp-edged elbows, it allows fluids to move smoothly through the turn, maintaining consistent flow without compromising system efficiency.


Can this bend be used in high-temperature piping systems?

Yes, the FBE coating and base material are designed to withstand moderate temperature fluctuations, making it suitable for most industrial and municipal applications. It maintains its structural integrity and corrosion resistance in typical operating temperature ranges.


How to ensure a proper seal when installing the double loose flanges?

To achieve a secure seal, clean the flange surfaces thoroughly before installation, align the bolts evenly, and torque them to the recommended specifications. The double loose flange design allows for minor adjustments to ensure full contact between the flange faces, minimizing leakage risk.
