Precision 90-degree redirection engineered to minimize internal turbulence and drastically reduce kinetic pressure drops.
Innovative Double EX socket configuration providing superior joint stability, mechanical restraint, and ground-shift compensation.
Customizable internal linings, including Fusion Bonded Epoxy (FBE), liquid epoxy, and Polyurethane (PU), specifically tailored for diverse fluid media and corrosive environments.
Strict manufacturing compliance with rigorous ISO2531 and EN545 international engineering standards, complete with available sanitary permits and third-party testing reports to guarantee smooth project inspections.
Available in a comprehensive range of exact dimensions from DN60 to DN600, accommodating both standard and highly specialized pipeline architectures.
The Custom-Lining Double EX 90° Bend represents a pinnacle of modern fluid dynamics engineering, carefully cast from heavy-duty ductile iron to serve the most demanding infrastructure projects. When you run your hand along the meticulously applied Fusion Bonded Epoxy interior, you immediately feel the ultra-smooth, glass-like finish. This specific internal topography is purposefully designed to eliminate surface friction and prevent the accumulation of abrasive microscopic sediments. This flawless inner surface translates directly to silent, unobstructed flow, drastically reducing the auditory hum, mechanical vibration, and kinetic stress typically associated with high-pressure fluid redirection. The exterior, dense and solid to the touch, speaks volumes about its structural integrity and its inherent resilience against deep-trench soil pressures, heavy top-loads, and unexpected mechanical impacts.
Beyond its tactile and visual craftsmanship, this fitting is purposefully built to solve critical alignment and separation vulnerabilities in complex pipeline architectures. By transitioning fluid streams at an exact right angle, it effectively mitigates the destructive forces of water hammer and sudden pressure spikes that plague standard fittings. Project managers, site engineers, and procurement specialists will appreciate how this single component fundamentally enhances the lifespan of the entire municipal or industrial network. It acts not merely as a turning point for potable water, aggressive stormwater, heavy wastewater, or volatile industrial chemicals, but as a heavily fortified anchor that protects the system from catastrophic joint failures. Ultimately, integrating this fitting safeguards your operational investments, ensures strict environmental compliance, and drastically reduces the need for unplanned, costly underground excavations and emergency maintenance.

Engineering a reliable, decades-lasting pipeline requires components that go far beyond basic fluid transition. Our 90-degree bend is loaded with strategic, field-tested enhancements designed to optimize both the immediate installation process and long-term operational efficiency. Every single unit is subjected to rigorous factory evaluation to guarantee peak performance under extreme environmental stress.
Heavy-Duty Ductile Iron Core: Provides exceptional tensile strength and ductility, ensuring the fitting easily withstands heavy top-loads, shifting soils, and aggressive internal pressures without micro-fracturing or structural fatigue.
Zero-Leakage Sealing Mechanism & Strict QC: The precision-molded sockets accommodate heavy-duty elastomeric gaskets that create an impenetrable, watertight barrier against fluid escape. Before leaving our facility, every fitting undergoes strict high-pressure hydrostatic testing and precise coating thickness verification to ensure absolute structural integrity.
Acoustic Dampening Properties: The thick, uniform metal walls combined with specialized interior coatings absorb the kinetic noise of rushing fluids, contributing to significantly quieter municipal water systems and reducing vibrational wear on connected infrastructure.
Weather Resilient Exteriors: When installed in exposed, above-ground environments, the specialized external coatings resist severe ultraviolet degradation and harsh atmospheric corrosion, maintaining their protective barrier through decades of environmental exposure.
Rapid-Lock Compatibility: Designed to integrate flawlessly with existing standard pipe profiles, allowing contracting crews to achieve secure, permanent connections in a fraction of the time required by traditional flanged alternatives.
Addressing the most critical and expensive vulnerability in pipeline engineering—joint separation—this fitting incorporates a highly sophisticated double EX socket architecture. Traditional single-socket or T-type joints often struggle and eventually fail under dynamic stress, but this dual-contact design fundamentally changes the structural integrity of the pipeline connection, offering unparalleled security for high-stakes fluid transmission.
Dual-Point Anchorage: By distributing mechanical stress and pulling forces across two distinct contact zones, the fitting effectively neutralizes the risks caused by ground settlement, seismic tremors, or severe temperature fluctuations.
Water Hammer Resistance: The heavily reinforced socket geometry absorbs and safely dissipates the sudden, violent kinetic energy spikes of water hammer effects, preventing catastrophic blowouts during pump start-ups or valve closures.
Elimination of Thrust Blocks: In numerous underground configurations, the superior restraint capability of the double EX socket reduces or entirely removes the need for pouring expensive, time-consuming concrete thrust blocks, accelerating project timelines.
Precision Installation Adaptability: To maximize site efficiency, we provide exact offset dimension tables and installation tolerance data. The Double EX socket design accommodates existing standard pipe networks perfectly, allowing field crews to align and secure connections rapidly without forcing unnatural angles.
Long-Term Maintenance Reduction: By virtually eliminating the risk of pipe decoupling under pressure, facility operators save exponentially on emergency excavation, labor, and pipeline repair costs over the entire lifecycle of the network.
Securing the physical integrity of large-diameter cast iron fittings during international transit is just as critical as the manufacturing process itself. We have developed a comprehensive delivery and technical support framework to ensure your project materials arrive in pristine condition and perform exactly as specified upon installation.
Every heavy-duty fitting is securely anchored within international export-standard, fumigation-free wooden crates and reinforced pallets. This meticulous packaging strategy prevents dangerous metal-to-metal contact, protects the specialized epoxy linings from impact damage, and guarantees that the heavy components remain completely unharmed during extended ocean freight and complex overland transport.
Beyond physical delivery, we stand behind our fluid transmission components with an engineering-grade warranty commitment. Our dedicated technical support team provides expert selection consulting, helping procurement managers and site engineers match the exact lining materials and dimensional tolerances to their specific fluid media. By offering this level of pre-installation guidance and post-delivery assurance, we actively help you reduce long-term maintenance overhead and prevent emergency underground repair costs from the very source.
