Flexible metal hose

Metal hoses are mainly used in the following scenarios:

• Conveying media: such as water, oil, gas, chemicals, etc.
• Connecting equipment: used to absorb vibrations, displacements, or thermal expansion in pipe systems.
• Protecting cables: as a protective sleeve for electrical cables.
• Special environments: suitable for high temperature, high pressure, and corrosive environments.

The corrugated inner tube is the core component of a metal hose, and its main functions include:

• Providing flexibility: allowing the hose to bend and stretch to adapt to complex installation environments.
• Withstanding pressure: the corrugated structure helps distribute pressure, enhancing the hose's pressure resistance.
• Reducing stress: absorbing stress caused by vibrations, displacement, and thermal expansion or contraction within the pipe system.

The sheath is the outer protective layer of a metal hose, typically made from braided stainless steel wire. Its main functions include:

• Enhancing strength: increasing the hose's tensile strength and pressure resistance.
• Protecting the corrugated inner tube: preventing external mechanical damage or corrosion.
• Extending service life: protecting the hose from harsh environments to make it more durable.

When selecting a metal hose, consider the following factors:

• Type of media: Choose the appropriate material based on the conveyed medium (water, oil, chemicals).
• Working pressure: Ensure the hose's pressure rating meets system requirements.
• Temperature range: Select hoses that can withstand high or low temperatures based on your application.
• Installation environment: Consider whether corrosion resistance, abrasion resistance, or explosion protection is needed. Size and length: Choose the appropriate diameter and length according to the piping system's needs.

The lifespan of a metal hose depends on various factors, including:

• Material quality: High-quality stainless steel materials tend to last longer.
• Operating environment: High temperature, high pressure, or corrosive environments can shorten the lifespan.
• Usage frequency: Frequent bending or vibration may lead to fatigue damage.
• Maintenance: Regular inspection and maintenance can extend the hose's lifespan.
  Generally, a high-quality metal hose can last 5-10 years or even longer under normal usage conditions.

Yes, regular maintenance ensures the performance and safety of a metal hose. It is recommended to:

• Inspect the appearance: Check for cracks, wear, or corrosion.
• Test the sealing: Ensure there are no leaks at the connections.
• Clean the interior: Prevent blockages or corrosion caused by residual media.
• Replace damaged parts: If the sheath is damaged or the corrugated tube is deformed, replace it promptly.

Yes, metal hoses can be customized, including:

• Size: Diameter and length can be tailored to specific needs.
• Material: Options include stainless steel, copper, titanium alloy, etc.
• Connection type: Flanges, threads, quick couplings, etc.
• Special requirements: Such as high temperature resistance, corrosion resistance, explosion-proof, etc.

When selecting a metal hose, consider the following factors:

• Working pressure: Ensure the hose's pressure rating meets system requirements.
• Temperature range: Select hoses that can withstand high or low temperatures based on your application.
• Installation environment: Consider whether corrosion resistance, abrasion resistance, or explosion protection is needed. Size and length: Choose the appropriate diameter and length according to the piping system's needs.

Metal hoses have the following advantages over rubber hoses:

• High-temperature resistance: Can withstand higher working temperatures.
• Corrosion resistance: Suitable for chemicals or corrosive media.
• Stronger pressure resistance: Able to withstand higher pressures.
• Longer lifespan: More durable in harsh environments.
• Environmentally friendly: Recyclable, reducing environmental pollution.

Metal hoses are more expensive primarily due to:

• Material costs: Stainless steel or other metal materials are more expensive.
• Manufacturing process: The production of corrugated tubes and braids is complex, requiring advanced technology.
• Performance advantages: Higher temperature, corrosion, and pressure resistance compared to regular hoses.
• Longevity: Although the initial investment is higher, they have lower long-term usage costs.

You can assess the quality of a metal hose based on the following aspects:

• Material: High-quality stainless steel should have a smooth surface and no impurities.
• Craftsmanship: The corrugated tube and sheath should be evenly braided, with no burrs or breakage.
• Weight: A heavier hose typically indicates better material quality and no shortcuts in production.
• Flexibility: High-quality hoses are flexible and won't easily deform or break when bent.
• Certifications: Check if the hose has relevant quality certifications (such as ISO, CE, etc.).
