The Variable Elbow Structural Pipe Fitting provides flexible angled connections between pipes, making it suitable for staircases, guardrails, and modular structures. Its adjustable range ensures versatility in both commercial and residential projects. With high-quality materials, advanced surface treatments, and precision design, it guarantees strength, durability, and long service life. This fitting is an essential component for creating safe, reliable, and adaptable pipe systems in various environments.
The Variable Elbow Structural Pipe Fitting is designed to connect two pipes at adjustable angles between 125° and 178°. It is widely used in staircases with slopes ranging from 45° to 88°, providing strong connections between the bottom uprights and handrails. It can also be applied in guardrail systems to connect two rails at angles of 45° to 78°, as well as in various DIY modular structures requiring angled pipe connections.
The core structure of the fitting includes an enlarged inner chamber that allows the two pipe ends to be adjusted to the desired angle. Once adjusted, the pipes are secured firmly in place by two hexagon socket bolts, ensuring stability and safety in use.
This fitting is designed for durability, offering flexibility for architects, builders, and DIY enthusiasts who need reliable angled joints. It is available in different materials and surface treatments, making it suitable for both indoor and outdoor environments. With its strong mechanical properties, simple installation, and adjustable design, the Variable Elbow is one of the most practical fittings for creating versatile, safe, and long-lasting structures.
Variable Elbow Structural Pipe Fittings are manufactured in cast iron, stainless steel, and aluminum to meet different project requirements.
Cast iron Variable Elbows are available in malleable iron and ductile iron. Malleable iron offers good machinability and strength for general construction, while ductile iron provides higher toughness and impact resistance. Both materials are cost-effective, durable, and reliable for heavy-duty applications. With galvanizing or powder coating, cast iron elbows are widely used in industrial and architectural pipe systems.
Stainless steel Variable Elbows provide superior corrosion resistance, making them ideal for outdoor, marine, or high-humidity environments. They combine strength with excellent aesthetics, offering a polished and professional appearance. These fittings are suitable for long-term projects where minimal maintenance is required. Stainless steel options are often chosen for premium guardrail systems, public installations, and environments where hygiene and durability are critical.
Aluminum Variable Elbows are lightweight yet strong, offering excellent corrosion resistance and easy handling during installation. Their light weight reduces transportation costs while still providing reliable performance. Aluminum fittings are widely used in lightweight structures, temporary guardrails, and DIY projects. They can also be anodized or powder coated for additional surface protection, ensuring long-lasting service in various applications.
Different surface treatments enhance durability and adapt fittings for various environments, ensuring longer service life and improved appearance.
Hot-dip galvanizing provides a durable zinc coating that protects the fitting against rust and corrosion. It is widely used for outdoor projects such as stair rails, guardrails, and industrial structures exposed to rain or moisture. The coating forms a metallurgical bond with the base metal, ensuring long-lasting protection. Hot-dip galvanized Variable Elbows are ideal for projects that require extended durability in harsh weather conditions while maintaining cost-effectiveness and reliability.
Double-coating galvanizing combines hot-dip galvanizing with an additional electro-galvanizing process, resulting in superior corrosion protection. This dual layer creates a more uniform and denser coating, enhancing wear resistance and durability. It is recommended for high-demand projects where fittings face continuous exposure to corrosive environments. Double-coated elbows are suitable for marine facilities, chemical plants, and industrial pipelines where extended service life and minimal maintenance are required.
Powder coating offers both protective and decorative benefits. The process applies a durable powder layer to the fitting, available in customized colors. This finish enhances corrosion resistance and provides a visually appealing surface. Powder-coated Variable Elbows are commonly used in architectural and commercial projects where aesthetics are important. They also perform well in indoor and outdoor environments, offering strong resistance to scratches, impacts, and weathering while allowing brand customization.
Confirm whether the size of the Variable Elbow meets the dimensional requirements of the pipe system.
Ensure the surface treatment is suitable for the environmental conditions where the fitting will be used.
