When choosing a flexible hose for your operation, it can be difficult to determine which option is best for your needs. Every flexible hose is designed to meet different specifications or to handle different substances, so it is crucial to choose a product that is suitable for your application. Choosing the wrong hose can drastically increase the risk of various safety hazards and equipment damage while reducing system performance and efficiency. That is why the experts at Flextech Industries have compiled some information to help you determine how to choose the right flexible hose and ensure the highest level of safety and efficiency for your system.

When looking at your options for flexible hoses, it is crucial to consider the following factors before making a final decision:
When choosing a flexible hose, you will need to consider the intended application. For example, hoses that transfer air will differ in many ways when compared to hoses that transfer water or gasoline. Other application-related considerations include the frequency at which the hose will be used and whether it needs to meet certain industrial or government standards. The environmental conditions that the hose will be exposed to will also affect which type of flexible hose is suitable for your needs, so it is crucial to consider each of these elements before making a final purchase.

The common working pressure of your application will have a direct impact on your options for flexible hoses. Whether the application calls for positive (PSI) or negative (Hg) pressure, choosing an inadequate hose can result in bursting or equipment damage. Be sure to understand your working pressure requirements to ensure that you are only looking at hoses that meet these specifications.

The selected hose must meet the diameter and length requirements of the job. Incorrect sizing will often result in clogs if the hose is too small or leaks if it is too large. This can be especially dangerous if the hose is used to transport fuel, hazardous materials, or substances that are extremely hot.
Is it time to replace your flexible hose?
All flexible hoses have a temperature rating that determines their resistance to extreme heat or cold. Failure to match these requirements with your application can result in frozen or melted hoses. Internal and external temperatures directly impact the type of hose that should be selected for the job, so be sure to consider both before selecting a product.

The type of piping used to connect two distant points to transport or transfer fluid is known as a flexible hose. Most flexible piping & metal hoses look similar. However, their dimension, thickness and size may vary according to the requirement of the application.
A flexible metal hose helps absorb vibrations, pipe movements, and noise. They are designed to connect misaligned rigid piping. They also help connect moving parts of machinery or equipment and are practical for hooking up frequently moved or dismantled equipment.
At Aeroflex, we manufacture customised flexible metallic hoses that are durable and corrosion & temperature resistant.
Upgrade Your Systems with Flexible Metal HosesA metal hose, commonly known as a hosepipe, is made from four basic components. Individually, these parts may appear very simple. But, when combined in a flexible metal hose assembly, they become an optimal solution for varied industries and applications.
Corrugated tubing is the main component of a flexible metal hose. It plays a key role in the significant value-added attributes of the assembly, such as flexibility, corrosion resistance, and pressure rating.
All corrugated tubing options vary in corrosion resistance ratings, pressure ratings, and levels of flexibility they can offer, making them the most important features of every flexible hose.

The braid is the second vital hose component that contributes to an assembly’s ability to withstand high pressures. Multiple factors contribute to a braid’s functionality, like the diameter of the wire, the wire number per carrier, the number of carriers on the braiding machine, and the percentage of braid coverage. You can also increase the pressure rating by adding additional layers of braid to the assembly.
The design of the braid can have a significant effect on the pressure rating and the life cycle of the hose. Thus, a braid package consisting of a high-percentage braid coverage (braided directly into the hose) should be used to ensure the braid is well-secured on the hose. This protects the assembly from potential deformation while ensuring a maximum life cycle.
Though braid collars only account for a small portion of the hose assembly, they are important. Inner corrugated hose and the braid are joined together in a seamless unit by braid collars during the cap welding process.
Besides helping join the hose components, the braid collars protect and isolate corrugations near the cap weld from any movement. Once the cap welding process is done, these corrugations turn into a “heat-affected zone”. This ensures the optimal functionality and durability of each hose.
Also, braid collars ensure that any bending stresses are evenly distributed over the right corrugations, thereby preserving the life cycle of the assembly.
The end-fittings are the final components added to an assembly. These fittings are available in numerous options, allowing flexible metal hose assemblies to be customised to suit varied applications. Before you select the fittings, ensure to verify the size, alloy, and pressure requirements of the application.
Flexible meta hose are manufactured in two basic styles, including corrugated stainless steel hose and interlock hose.
A regular hose cannot sustain the longitudinal pressure stress and tends to squirm under internal pressure. Thus, to resist the longitudinal pressure stress and prevent it from squirming, corrugated hoses are often constructed with braid wrappings around the outer surface. A corrugated hose is constructed with a long length bellow, and the braid protects the corrugation from scratch and wear. This type of hose is suitable for handling any type of gases and liquid that are compatible with the material of the hose.

The construction of an interlock hose involves links that are kept tight with the packaging material. Clearances are provided between these links to make them capable enough to accommodate some axial movement that gradually closes as the hose is bent.
When the clearances are completely closed, the hose becomes stiff, restricting any further bending. This sudden stiffness is a warning to the handler, preventing the interlocked hose from being over-bent and causing potential damage.
The automatic warning feature makes this hose ideal for manual handling. Also, the outer surface of the interlocked hose is relatively smooth, making handling easy without any covering.
However, its packaging does not offer a perfect seal. Hence, it is satisfactory for carrying low-pressure air, steam, and water but not apt for conveying gases and liquids such as kerosene and alcohol.
