There are many different types of hose available on the market, including metal, rubber, composite, PTFE, etc. Typically metal hose is used when no other (non-metallic) construction will work. The decision of which hose type to buy depends on the application for which the hose is being used. Some of the factors listed below should alert you to consider using metal hose.
1. Temperature Extremes: If either the temperature of the media going through the hose or the surrounding atmospheric temperature is very hot or cold, metal may be the only material that can withstand the extreme temperatures.
2. Abrasion: To prevent abrasion, a metal hose braid can be used as a protective cover over wires or other hoses. Metal braiding can be abrasion resistant, making it ideal for use as protection to corrugated hose from either abrasive media or external damage. It can also be applied to the outside of corrugated hose to prevent it from over bending or kinking.
3. Flexibility: Not only are metal hoses generally more flexible than industrial hoses, but they can also have a wide variety of end configurations. Any weld-able fitting can be incorporated into a metal hose assembly in any configuration, while other hose types require special shanks and collars. This can be a benefit over other hose types that would require multiple threaded connections to connect several hoses together. Every threaded connection is a potential leakage point, so this is something to consider.
As always, follow the “STAMPED” acronym set forth by NAHAD to determine the best hose for the application.
