How do I know if I need to use flexible metal?

Knowing when to use flexible metal products can be tricky. Let us help guide you through the decision making process.

There are many different types of hoses and expansion joints available on the market, including metal, rubber, composite, PTFE, and fabric. The decision of which hose type to select depends on the application for which the hose is being used.

Generally, there are eight factors to consider to help you to know when to use flexible metal hose:

1. TEMPERATURE EXTREMES

   .  If either the temperature of the media going through the hose or the surrounding atmospheric temperature is very cold or hot, metal may be the only material that can withstand such temperature extremes.

2. CHEMICAL COMPATIBILITY

   .  Metal hose can handle a wider variety of chemicals than most other hose types. If the hose will be exposed to aggressive chemicals (either internally or externally}, metal hose should be considered. Here is a great resource to check chemical compatibility.

3. PERMEATION CONCERNS

   .  Non-metal hose is susceptible to gas permeation through the hose wall and into the atmosphere. Metal hose, on the other hand, does not allow permeation. If containing the gases inside the hose is important, metal hose may be required.

4. POTENTIAL FOR CATASTROPHIC FAILURE

   .  When a metal hose fails, it usually develops small holes or cracks. Other hose types tend to develop larger cracks or come apart completely. If a sudden hose failure is potentially catastrophic, a metal hose may help minimize the effects of a failure by leaking product at a slower rate.

5. ABRASION AND OVERBENDING CONCERNS

   .  To prevent abrasion and over-bending, a metal hose can be used as a protective cover over wires or even other hoses.

6. FIRE SAFETY

   .  Other hose types will melt when exposed to fire, while metal hose maintains its integrity up to ° F. (See NAHAD derating chart).

7. ACHIEVING FULL VACUUM

   .  Under full vacuum, metal hose maintains its shape while other hose types may collapse.

8. FLEXIBILITY IN FITTING CONFIGURATION

   .  Virtually any type of fitting can be attached to metal hose, while other hose types require special shanks and collars.

What is Inside a Flexible Hose?

Posted: August 31, |Category: Flexible Hoses

Flexible hoses are commonly used in a variety of industries to transport materials such as fuel, chemicals, water, and steam. Though most flexible hoses have a similar appearance, there are many different options in terms of size, thickness, and the dimensions of each component. As leading providers of flexible hoses for all types of industries and materials, the team at Flextech Industries understands the complexities of hose assemblies. That is why we have provided some information outlining what is inside a flexible hose to help owners understand how they work and how to choose the right option.

Learn more about the important components that make up a flexible hose.

Components Inside a Flexible Hose

Most flexible hoses contain the following components:

Corrugated Tubing

The corrugated tubing is the core component of a flexible metal hose. It comprises the bulk of each assembly while playing a part in key value-added attributes such as corrosion resistance, pressure rating, and flexibility. All corrugated tubing options feature different corrosion resistance ratings, pressure ratings, and levels of flexibility. This makes corrugated tubing the most important part of every flexible hose.

Learn about the importance of choosing the right flexible hose.

Braid

The second component of metal hoses is the braid. The braid covers the corrugated tubing, directly influencing pressure rating. There are many factors that affect the durability and flexibility of each braid including the wire diameter, the number of wires per carrier, and the percentage of braid coverage. Choosing the right braid configuration is crucial for protecting the hose from deformation and ensuring a long usable life.

What are the different types of flexible hoses you can choose from?

Braid Collar

Though they only account for a small portion of the hose assembly, braid collars play a vital role. All braid collars are designed to join the inner corrugated hose and the braid together into one seamless unit. Each collar also works to ensure that any bending stress is properly distributed over the right corrugations, optimizing the functionality and durability of each assembly.

End Fittings

The final component added to an assembly is the fittings. These components allow the flexible hose assembly to fit into a certain connector, spigot, or other receptacle. To ensure the best possible fit, all end fittings should be thoroughly examined to verify that the size, alloy, and pressure ratings match the requirements of the application.
