When To Use Metal Hose – 8 Important Factors to Consider


At times, the usage of the metal hose is pretty hard to determine and thereby the query “when to use metal hose” is among the frequently asked by many US homeowners today. As such, there’s a growing fleet of hose in the market be of metal, rubber, composite, PTFE and fabric. According to a general rule, a metal hose comes into use when other (non-metallic) construction fails at work miserably.

In simple words, a metal hose is viewed as a last resort. Most importantly, the decision about the right hose to buy is always influenced by the application for which the particular hose is created.

For now, study these eight factors that give you the correct inclination of using metal hose:

1.Temperature Extremes

Some extreme conditions in which either the temperature of the media passing through the hose or the surrounding atmospheric temperature is measured as very cold or hot, the metal may be the only option left that can survive with these sort of temperatures.

2. Chemical Compatibility

Unlike other hose types, the highly-efficient metal hose is excellent for handling a variety of chemicals. Additionally, if the hose has possibilities to expose to aggressive chemicals (no matter internally or externally), the metal hose should be deeply considered.

Know that the stainless steel can exhibit strong resistance to many common chemicals and special alloys are put into effect for better corrosion resistance. Please emphasize on our piece of advice that special care is mandatory to make sure that all assembly components in cooperation are resistant to chemical attack, both suspected from the media conveyed and the physical environment.

3. Permeation Concerns

A non-metal hose is believed to be the one having gases that travel through the hose wall and later, into the atmosphere. While a metal hose does not allow permeation and is rather preferred by the experts.

4. Potential for Catastrophic Failure

Don’t consider a metal hose as an irreplaceable metal line element. It can also fail, and when it does, the paramount damage it leads to is small holes and cracks. Other hose types, if fail, can cause more substantial cracks and ultimately fall apart. That’s why in non-metallic hoses, barbed fittings are mounted onto the hose ends with the mutual assistance of clamps or crimped collars. Furthermore, if a sudden failure of the hose is predicted, a metal hose works by minimizing the chances of failure by leaking product at a slower rate.

5. Abrasion and Over bending Concerns

In order to avoid abrasion and over bending, a metal hose is made a protective cover over wires or even other hoses. So far, the stripwound hose can be extremely abrasion resistant, creating an ideal atmosphere to prevent both external damage and abrasive media arrival. Here, bending a corrugated hose is another successful way to fatigue the metal hose of an assembly.

6. Fire Safety

It is worth noting that other hose types will melt straightaway when exposed to fire, but the metal hose is a guaranteed product for its integrity which is up to 1200º F. Almost all, flexible corrugated hoses are all-metal (unless a fitting maintains a non-metallic seal), which even makes them called naturally fire-resistant. However, the low permeation and fire resistance define corrugated hoses the relatively preferred choice for barge loading and unloading applications.

7. Achieving Full Vacuum

As compared to other standard hose types which collapse in no time, a metal hose, under full vacuum is well-reputed in the market to maintain its shape for a prolonged period. On top of that, the corrugations in a metal hose provide it with an incredible hoop strength, which in exchange, hand over it the ability to handle a full vacuum.

8. Flexibility in Fitting Configuration

As the name suggests, any weld-able fitting is held into a corrugated metal hose assembly, and with any configuration, whereas other hose types need special shanks and collars. This can emerge as a loud benefit over different hose types that may require multiple threaded connections to connect several hoses at the same time.
