Metal hoses are utilized in a variety of industrial applications that need to transfer fuel, chemicals, or extremely hot fluids. While these products are ideal for a variety of industries, they are often more expensive than conventional rubber hoses, leading many operations to opt for cheaper products. While these products cost less, they can significantly increase the risk of leaks, bursting, and other safety hazards. That is why the team at Flextech Industries has compiled some information on important factors to consider to help you understand when to use metal hoses for your operation.
Learn how to maximize the life of your hose assembly.
If you are trying to determine which type of hose is best for your application, it is important to consider the following factors:
Metal hoses can safely handle more chemicals than hoses constructed from other materials. If the interior or exterior of the hose will be exposed to aggressive chemicals, metal hoses should be considered. Stainless steel hoses are highly resistant to most chemicals, making them a popular choice for various applications. Thorough care should be taken to make sure that all assembly components are resistant to each chemical present, both from the media conveyed and the surrounding environment.
What’s inside a flexible hose?
If the temperature of the media going through the hose or the surrounding atmospheric temperature is extremely cold or hot, metal may be the only material that is suitable for the job. Other materials—like rubber—can freeze or melt, leading to leaks and downtime while repairs are made.
Learn all about high-temperature flexible hoses.
Abrasion and overbending can cause significant damage to hoses, accelerating wear and reducing their usable life. To prevent abrasion and excessive bending, a metal hose can be used as a protective cover over wires or other hoses. Strip wound hoses are exceptionally resistant to abrasions, making them ideal for use as a protective layer. These hoses can also be applied to the outside of a corrugated hose to prevent it from overbending.
Learn how to properly fabricate metal hose assemblies.
Many hose materials will melt when exposed to fire and extreme heat. Metal hoses maintain their integrity up to 650°C. Flexible corrugated hoses are usually all-metal (unless a fitting contains a non-metallic seal), making them naturally fire-resistant. Low permeation and fire resistance make corrugated hoses the preferred choice for barge loading and unloading applications, or any application where the hose may be exposed to an open flame.
