Description
Flexible Stainless Steel Hose: Robust, Reliable, and Versatile
Flexible Stainless Steel Hose, a pinnacle of engineering designed for a variety of industrial applications.
The hose product is primarily composed of a corrugated tube, a mesh cover, and end fittings or flanges. The inner tube features a thin-walled stainless steel corrugated pipe with either a spiral or annular waveform, ensuring durability and flexibility.
Construction
- Corrugated Tubes: Available in spiral and annular waveforms.
- Spiral Corrugated Tubes: Provide flexibility and are typically made from seamless or welded tubing.
- Annular Corrugated Tubes: Known for excellent elasticity and low stiffness, they’re often used in shorter pipes or equipment.
- Mesh Cover: Made from stainless steel wire or strip, it enhances the hose’s pressure resistance and protects the corrugations, tailored to specific parameters for enhanced durability.
- Fittings and Flanges: Available in various styles to suit different engineering needs of your piping systems.
Material Excellence
Crafted from austenitic stainless steel, our Flexible Stainless Steel Hose guarantees exceptional temperature resistance and corrosion resistance. This material choice ensures that the hose can operate effectively in a wide temperature range from -196°C to 600°C.
Functionality
- Reduces Installation Stress: Minimizes the stress on piping during installation.
- Compensates for Pipe Movement: Accommodates movement in the piping system.
- Absorbs Vibrations: Ideal for systems that experience vibrations.
Broad Range of Industrial Applications:
Our Flexible Stainless Steel Hose is versatile, suitable for systems requiring high flexibility, vibration isolation, and robustness.
Metal flexible hoses are extensively used in aviation, aerospace, petroleum, chemical, metallurgy, power generation, paper, textile, construction, medicine, food, tobacco, and transportation.
They also find applications in railways, HVAC systems, machinery, automation control, power distribution, communication systems, ships, buildings, and outdoor exposed wiring protection.
It is ideal for conveying steam, gas, air, heavy oil, petroleum, and various chemical pharmaceuticals.
- Versatility: Compatible with a wide range of mediums, ensuring operational excellence in diverse environments.
- Flexibility: Essential for conveying systems requiring high flexibility.
- Vibration Isolation: Optimal for areas with vibration, suitable for steam, gas, air, heavy oil, petroleum, and chemicals.
- Pressure Range: Generally operates within PN0.6 – 32.0Mpa, up to 42.0Mpa.
- Temperature Range: Functions effectively from -196℃ to 600℃.
- Material Selection: Based on the medium’s corrosivity to ensure corrosion resistance.
Features and Advantages of Our Metal Flexible Hose
Corrosion Resistance
- Chromium Content: The corrosion resistance of our metal flexible hose primarily depends on its chromium content. When the chromium level reaches 10.5%, there’s a significant increase in atmospheric corrosion resistance. Higher chromium content continues to improve corrosion resistance, though the increment is less pronounced.
- Alloying with Chromium: Alloying steel with chromium alters the surface oxide, forming a protective layer similar to pure chromium metal.
- Protective Oxide Layer: This thin, adherent chromium-rich oxide layer shields the surface, preventing further oxidation.
- Self-Repairing Feature: The natural luster of stainless steel is visible through this layer. If damaged, the exposed steel surface interacts with the atmosphere to self-repair, reforming the “passive film” and maintaining protection.
Design Specifications:
- Recommended Expansion Per Corrugation:
- Full-Height Type: ±24mm
- Half-Height Type: ±12mm
- Dust Shields:
- For ducts with minimal dust, dust shields may not be necessary. However, for dustier flue applications, using dust shields is recommended.
- Corrugation Considerations:
- To reduce the number of corrugations, consider a 50% cold drawing process.
- Standard Application Sizes:
- Standard Half-Height Metal Hose: Ideal for sections with an area smaller than 4.6 square meters and dimensions where one side is less than 1.5m but more than 0.6mm.
- Standard Full-Height Metal Hose: Suitable for all types of smoke and air ducts.
