Braided Metallic Hose: Production, Features, Benefits, and Applications


Braided metallic hoses are versatile and essential components used in various industries for their protective qualities and durability. This article explores the production process, features, benefits, and applications of braided metallic hoses. We will delve into the advantages and potential drawbacks of this type of hose, along with examples of its uses in different industries.

Production of Braided Metallic Hose

Braided metallic hoses are typically manufactured using a combination of advanced manufacturing techniques and high-quality materials. The production process involves the following steps:

Material Selection: The inner tubing of the hose is often made of flexible materials such as rubber, PTFE (polytetrafluoroethylene), or thermoplastic, which offer chemical resistance and flexibility. The outer braiding is commonly constructed from stainless steel or other metal alloys for enhanced strength and protection.

Braiding: The outer metal braiding is created by interweaving individual metal strands or wires in a helical pattern around the inner tubing. This braiding provides structural support, prevents kinking, and protects the hose from external abrasion, impact, and environmental factors.

The interweaving machine used in creating the outer metal braiding of braided metallic hoses works by feeding individual metal strands or wires through a series of guides and tensioning devices. These strands are then interlaced or woven together in a helical pattern around the inner tubing. The interweaving machine typically utilizes rotating spindles or bobbins to control the movement and positioning of the metal strands, ensuring a consistent and uniform braiding. The machine's controls and mechanisms allow for precise adjustment of tension, speed, and direction to achieve the desired braiding pattern and density. The result is a tightly woven, protective metal sleeve that enhances the hose's strength and resistance to abrasion.

Typical Assembly and Connections

The braided metallic hose is assembled by securely attaching the end fittings, which can be customized to suit specific applications. These fittings are typically made of metal and are designed to provide a leak-free connection to other components or systems.

Specific fittings or connectors used with braided metallic hoses can vary depending on the application, industry, and specific requirements of the system. Different fittings may be chosen based on factors such as pressure rating, compatibility with the fluid or gas being transferred, and environmental conditions. Typical fittings or connectors used for braided metallic hoses include:

Flanges: Flanges are widely used fittings for braided metallic hoses. They consist of a flat, circular plate with evenly spaced bolt holes around the perimeter. Flanges are attached to the end of the hose and provide a secure connection to another component or system by bolting them together.

Threaded Connectors: Threaded connectors, such as male and female threaded fittings, are commonly used to connect braided metallic hoses to other threaded components. These connectors feature external or internal threads that enable a tight and reliable connection.

Camlock Couplings: Camlock couplings, also known as cam and groove fittings, are popular for quick and easy connections. They consist of male and female couplers with matching cam arms that lock together for a secure connection. Camlock couplings are widely used in industries such as petroleum, chemical, and agriculture.

Quick Disconnect Couplings: Quick disconnect couplings, also called quick-release couplings or quick connects, provide a convenient and efficient way to connect and disconnect braided metallic hoses. These fittings feature a mechanism that allows for rapid connection and disconnection without the need for tools.

Compression Fittings: Compression fittings are commonly used in applications where a leak-free connection is essential. These fittings consist of a compression nut, ferrule, and body. As the nut is tightened, it compresses the ferrule against the body, creating a tight seal.

Swivel Joints: Swivel joints are utilized in applications that require flexibility and rotational movement. They allow the braided metallic hose to rotate freely, preventing kinks and strains in the hose assembly.

Features of Braided Metallic Hose

Protection and Durability: The primary feature of braided metallic hoses is their ability to safeguard the inner tubing from abrasion, external impacts, and aggressive environments. The braided metal sleeve acts as a protective cover, ensuring the integrity and longevity of the hose.
