The Double Male Swivel Structural Pipe Fitting is a versatile connector widely used in guardrails, handrails, and structural systems. Designed to work with single swivel female components, it provides flexible joint solutions that enhance structural adaptability. With durable materials, multiple surface treatment options, and precise design, this fitting ensures reliability in various environments, offering strong performance and easy installation for construction, industrial, and commercial projects.
The Double Male Swivel Structural Pipe Fitting is a specially designed component intended to be used together with the 173F Single Swivel Combination Female Part. When connected by riveting or bolting, the two components form a new fitting, known as the 167 Double Swivel Combination. This combination allows for flexible angular connections between pipes, making it particularly suitable for non-standard railing angles or unique construction designs.
Beyond its primary use with female swivel fittings, the Double Male Swivel has also developed into other practical applications. It can serve as a connecting point between uprights and various accessories, such as chains, mesh panels, or other linking materials. This adaptability makes it valuable in industries requiring both safety and flexibility, such as warehouses, construction sites, and public facilities.
Structurally, the fitting features two ears on both sides of its socket, each equipped with a hole to allow secure attachment to female swivel fittings or other structures. Additionally, the socket includes an internal hex bolt designed to fix the Double Male Swivel securely to the pipe. This robust structure ensures stable performance, strong load-bearing capability, and long service life.
HULK Metal provides multiple material options for Double Male Swivel Structural Pipe Fittings to meet strength, durability, and customization needs.
Cast iron Double Male Swivels are available in malleable iron and ductile iron. Malleable iron offers excellent machinability and cost-effectiveness, while ductile iron provides higher tensile strength and impact resistance. Both materials deliver reliable durability, making them suitable for structural applications. These options ensure strong performance in construction projects, handrails, and other heavy-duty installations.
Stainless steel Double Male Swivels offer superior corrosion resistance and durability, making them ideal for outdoor, marine, and highly humid environments. They maintain structural integrity under harsh conditions and provide an attractive appearance with minimal maintenance. Although requiring higher investment, stainless steel fittings are an excellent choice for projects demanding long service life, strength, and enhanced aesthetics.
Aluminum Double Male Swivels are lightweight yet strong, offering a balance between performance and ease of installation. They are resistant to corrosion, cost-effective, and suitable for less demanding applications where weight reduction is a priority. Ideal for temporary or portable structures, aluminum fittings enable quick assembly and disassembly while maintaining adequate structural reliability in everyday use.
Different surface treatment methods enhance performance, corrosion resistance, and aesthetic value to suit diverse environmental and functional requirements.
Hot-dip galvanizing creates a thick and durable zinc coating, providing excellent protection against rust and corrosion. It is especially effective in outdoor or humid environments where exposure to moisture is common. The process ensures uniform coverage, long-lasting performance, and minimal maintenance. This surface treatment is widely used in construction projects, guardrails, and industrial facilities where structural integrity and reliability are critical in demanding working conditions.
Double-coating galvanizing is an advanced method built upon hot-dip galvanizing by adding an electro-galvanized layer for extra protection. This process ensures a denser, smoother, and more aesthetically appealing surface. It significantly enhances corrosion resistance and provides longer service life, even in environments with higher exposure to chemicals or saltwater. This treatment is ideal for industries requiring high-performance and visually refined structural fittings that must endure tough environmental challenges.
Powder coating provides both protective and decorative benefits, offering a wide range of colors and finishes. The coating is applied electrostatically and cured for a uniform, durable, and attractive surface. This treatment resists chipping, scratching, and fading while also improving corrosion resistance. Powder coating is suitable for projects that require custom colors and enhanced visual appeal, making it popular in architectural and commercial applications where aesthetics are important.
l Confirm the size specifications of the Double Male Swivel to ensure it meets system and structural requirements.
l Select the surface treatment that matches the operating environment to guarantee long-term durability.
l Ensure the fitting complies with local installation standards and safety regulations.
