Double EX Socket 90 deg Bend


Understanding the Product


The Double EX Socket 90 Deg Bend is a specialized piping fitting designed to redirect fluid flow at a precise 90-degree angle in industrial, commercial, and municipal piping systems. Unlike conventional bend fittings, its double EX socket design offers enhanced stability and deflection capabilities, making it a preferred choice for applications where joint integrity and flexibility are critical. This fitting acts as a seamless transition between straight pipe sections, ensuring smooth flow while minimizing pressure loss and turbulence. Crafted to work with a range of piping materials, it stands out for its ability to prevent joint separation—even in high-pressure or dynamic environments.


Core Advantages


Enhanced Joint Stability

The double EX socket configuration creates dual points of contact between the fitting and pipes, eliminating the risk of joint separation common in single-socket bends. This design ensures the fitting remains securely connected, even under fluctuating pressure or mechanical stress, reducing maintenance and replacement costs.


Superior Deflection Capability

Compared to T-type joints and standard bends, this 90 deg bend offers greater deflection, allowing for minor adjustments during installation to accommodate alignment variations. This flexibility simplifies on-site fitting, reduces the need for custom modifications, and ensures a perfect fit even in complex piping layouts.


Versatile Lining & Coating Options

Beyond the standard Fusion Bonded Epoxy (FBE) coating, the fitting offers customizable internal linings and external coatings—including epoxy paint and PU—tailored to specific application needs. These options enhance corrosion resistance, chemical compatibility, and durability, making the fitting suitable for diverse fluid types and environmental conditions.


Typical Uses


Water Plant & Reservoir Piping

Water treatment plants and reservoirs rely on this 90 deg bend to redirect water flow between treatment stages, storage tanks, and distribution lines. Its leak-proof design and corrosion resistance prevent contamination and ensure the delivery of clean water to end-users.


Storm Water & Sewage Systems

In stormwater drainage networks, the fitting efficiently redirects runoff around structures, roads, and landscapes, preventing flooding and waterlogging. It is also ideal for sewage collection systems, where its joint stability and chemical resistance ensure reliable transport of wastewater to treatment facilities.


Fire Fighting & Industrial Piping

Fire fighting systems demand fittings that can withstand high pressure and deliver unobstructed flow—this double EX socket bend meets those requirements, ensuring water reaches fire suppression equipment quickly and efficiently. In industrial settings, it is used to redirect fluid lines in manufacturing plants, chemical processing facilities, and irrigation systems.


Design Specifications


Structural Design

The 90-degree angle is precision-engineered to ensure optimal flow dynamics, minimizing turbulence and pressure drop. The double EX sockets are molded to exact dimensions, ensuring a tight, secure fit with compatible pipes. The fitting’s robust construction includes reinforced walls at the bend point, enhancing strength and resistance to impact and wear.


Material & Coating Options

Constructed from high-quality materials selected for their durability and compatibility with diverse fluids, the fitting offers multiple lining and coating choices. The FBE coating provides exceptional corrosion resistance, while epoxy paint and PU options cater to specialized needs—such as chemical resistance or UV protection.


Compliance & Performance

Adhering to international standards including ISO2531 and EN545, the Double EX Socket 90 Deg Bend undergoes rigorous testing to ensure pressure resistance, leak tightness, and structural integrity. It is designed to operate reliably in a wide range of temperatures and pressure conditions, making it suitable for both indoor and outdoor applications.


FAQ


Q: What makes this bend different from standard 90-degree fittings?

A: The double EX socket design is the key difference—unlike standard single-socket bends, it offers dual connection points for enhanced stability and deflection. This prevents joint separation and allows for minor alignment adjustments, making it more reliable in dynamic or high-pressure systems.


Q: Can I use this fitting with high-temperature fluids?

A: The fitting’s temperature tolerance depends on the selected lining and coating. Standard configurations are suitable for moderate temperatures, while specialized coatings can be chosen for high-temperature applications. Always check the product specifications or consult with a professional to ensure compatibility with your fluid temperature range.


Q: How do I select the right lining/coating for my application?

A: Consider the type of fluid being transported (e.g., potable water, wastewater, chemicals) and environmental conditions (e.g., outdoor exposure, corrosive atmospheres). For potable water, FBE or epoxy paint is ideal; for chemical fluids, PU or specialized epoxy linings offer enhanced resistance. Consult with a piping expert if you’re unsure.
