The Single Swivel Combination Structural Pipe Fitting is designed for applications requiring adjustable angles that other fittings cannot achieve. It is created by riveting or bolting two swivel components together and is widely used in guardrail and handrail systems. While not suitable for direct lateral load bearing, it provides versatile connection solutions when paired with other fittings, making it highly valuable for flexible structural pipe frameworks.
The Single Swivel Combination is assembled from two fittings, making it suitable for structures where adjustable angles are required but standard fittings fail. However, it cannot bear lateral loads on its own. If lateral strength is needed, it must be used together with other fittings. Its sleeve cannot be used to connect two pipes directly.
Commonly used in guardrail and handrail systems during installation, allowing the uprights to secure adjustable top rails.
Suitable for adding a mid-rail to the end upright in rail structures.
In DIY frameworks, it can be used to add vertical sockets to specific pipe positions.
Not recommended for already completed systems.
Must be paired with other fittings if used to bear lateral loads.
The sleeve is not intended for connecting two pipes.
The Single Swivel Combination is riveted or bolted together using the 173M Male Single Swivel Socket and 173F Female Single Swivel Socket. The 173F socket is designed to fit the pipe end, while the 173M sleeve is used to cover the pipe, enabling adjustable angle connections.
By combining the male and female swivel sockets, the fitting allows flexible angle adjustment between pipes. When installed, it offers a secure yet adjustable joint, suitable for top rails or angled pipe positioning in structural systems.
Single Swivel Combinations are available in cast iron, stainless steel, and aluminum to suit strength, durability, and application needs.
Available in both malleable iron and ductile iron, cast iron Single Swivel Combinations provide excellent durability and cost-effectiveness. They are widely used in guardrail and handrail systems due to their balance of strength, wear resistance, and affordability in bulk applications.
Stainless steel Single Swivel Combinations provide superior corrosion resistance and durability, making them ideal for harsh or outdoor environments. Their smooth finish offers excellent appearance while maintaining high structural reliability. Suitable for industries requiring hygienic standards, such as food, chemical, or marine applications.
Aluminum Single Swivel Combinations are lightweight yet durable, making them ideal for projects where weight reduction is critical. Their natural corrosion resistance ensures long service life in outdoor or marine conditions. They are often preferred for custom-designed DIY or lightweight structural pipe systems.
Multiple surface treatments provide corrosion resistance, aesthetic appearance, and durability, ensuring the fittings perform well in various application environments.
Hot-dip galvanizing forms a strong zinc coating on the fitting surface, giving it long-term protection against rust and corrosion. It is suitable for outdoor applications or industrial environments where fittings are exposed to moisture or harsh conditions. The coating bonds tightly, ensuring reliable durability and extended service life.
Double-coating galvanizing combines hot-dip galvanizing with an additional electroplated zinc layer. This dual protection offers enhanced resistance to wear and corrosion, extending the fitting's service life in challenging environments. It is an ideal solution for industries requiring both strong performance and cost efficiency.
Powder coating provides a uniform, customizable finish available in various colors. It adds both protection and aesthetic appeal, making it suitable for decorative or branded projects. Customers must confirm their required color and minimum order quantity in advance, ensuring production matches the intended use and design requirements.
l Confirm whether the size of the Single Swivel Combination meets the system requirements.
l Check if the surface treatment can withstand the intended usage environment.
l Ensure compliance with local installation and safety standards.
l If used for lateral load bearing, pair with additional fittings to ensure proper strength.
