Flexible Metal Hoses for Industrial Applications

Flexible metal hoses are essential in many industries for their strength, flexibility, and resistance to harsh conditions. Manufactured from high-quality metal alloys like stainless steel, bronze, and Inconel, these hoses deliver durability and superior performance in challenging environments. Their corrosion resistance and ability to withstand high temperatures make them a top choice for various industrial uses.

Flexible metal hoses and metal hose pipes are used to transport fluids, absorb vibrations, and reduce noise and pipe movements. These hoses are perfect for applications involving misaligned rigid piping or where frequent movement or dismantling of equipment is necessary. At QualityFlex, we specialize in manufacturing flexible metal hose pipes that can endure the toughest conditions, offering corrosion and temperature-resistant solutions for various industries, including industrial machinery and piping systems.

Types of Flexible Metal Hose

Flexible metal hoses come in two primary types: corrugated metal hoses and interlock hoses, each with unique advantages for different applications.

Corrugated Metal Hoses Corrugated metal hoses are designed to handle internal pressure stresses. They feature a corrugated structure wrapped with a protective braid, preventing squirming and enhancing durability. This type of metal braided hose pipe is ideal for transporting various gas and liquids compatible with the hose material. The braided layer ensures long-lasting performance in demanding environments, protecting the hose from wear and tear. 

Interlock Hoses Interlock hoses consist of linked sections with built-in clearances to allow for limited axial movement. As the hose bends, these clearances close, and when fully closed, the hose stiffens, signaling the handler to avoid over-bending. This design makes interlock hoses ideal for manual handling. They are suitable for carrying low-pressure air, steam, and water but are not recommended for volatile liquids or gas, as the packaging does not offer a perfect seal.

Both types of metallic flexible hose pipes ensure reliability, flexibility, and safety, depending on your specific application.

What Are Metal Hoses?

Metal hoses are essential connecting components composed of a flexible pipe, a net sleeve, and joints. These hoses offer excellent elasticity and minimal stiffness, making them ideal for absorbing movement and handling pressure fluctuations. The net sleeve, typically made of stainless steel wire, enhances the hose’s pressure capacity and protects the internal bellows.

Available in various joint styles, flexible metal hoses can be customized to suit specific project needs. Widely used in industries like aerospace, petroleum, chemical processing, mining, electronics, and shipbuilding, they offer length, temperature, and angle compensation in dynamic systems.

Choosing the Right Flexible Metal Hose Pipe for Your Application

Flexible metal hose assemblies are ideal for replacing rigid metal tubes where more flexibility is needed. Depending on your needs, you can select from various metal hydraulic pipes and hose types:

Standard Hoses (e.g., Parker 9A Hose): Suitable for general applications.

Ultra Flexible Hoses (e.g., Parker 9M Hose): Ideal for applications requiring a reduced minimum bend radius.

High-Pressure Hoses (e.g., Parker 9H Hose): Designed for high-pressure applications up to 5800 psi.

Made from stainless steel, these flexible metal hoses offer excellent resistance to chemicals and extreme temperatures. The corrugated core allows for flexibility, while the braided outer layer reinforces the hose to withstand high pressure.

Applications of Flexible Metal Hoses Across Industries

Flexible metal hoses are used in various industries due to their durability and flexibility. Here are some key applications:

Chemical Processing: Used to transfer corrosive chemicals and acids, thanks to their corrosion resistance.

Food and Beverage: Perfect for transferring food products and liquids due to their hygienic design and ease of cleaning.

HVAC Systems: Utilized to transfer air and gas in heating, ventilation, and air conditioning systems, withstanding high temperatures and pressure.

Marine Industry: Ideal for transferring liquids and gas in marine environments, offering high resistance to corrosion, pressure, and temperature.

Oil and Gas: Used for transferring oil, gas, and other fluids in drilling and production operations, withstanding extreme temperatures and pressure.

Conclusion

Flexible metal hoses are crucial in many industries, offering flexibility, durability, and resistance to corrosion, high temperatures, and pressure. Whether it’s chemical processing, food and beverage, HVAC, marine, or oil and gas applications, these metal braided hose pipes provide reliable solutions for critical industrial needs.
