Flexible hoses are designed to transfer fluids like water, oils, chemicals, steam, and air. Thanks to their flexibility, these units are commonly used in many industries. Here are a few important factors to consider when choosing flexible hoses for particular applications. 

1. Operating temperature

In general, the temperature has a significant impact on the physical property of any material. That’s why it is essential to take operating temperature and pressure into consideration. The type of flexible hose and its components like attachments or fittings can determine the temperature limits.

2. Connection pipe size

The size of a flexible hose for a specific application is often decided by the measurements of the existing matting and piping fittings. Nevertheless, other considerations like velocity, flow rate, and pressure drop also impact your selection of a proper hose size.

3. Pressure rating

The pressure rating of each flexible hose is determined by the actual conditions like bending stresses, temperatures, pulsating or shocking conditions. On average, every flexible hose manufacturer India offers the text pressure at 150 percent of the maximum operating pressure, which is often at 25 percent of the nominal one.

4. Media versus the corrosion of the flexible hose materials

An important factor to take into consideration when choosing a flexible hose is to choose a material that can be resistant to the media which will be transferred through the unit. This should be done in every application. Keep in mind about the corrosive impacts of the outside conditions, as well as the fluids covered inside. Both of these things are important. Also, you should remember that a flexible hose, which has a thin-walled material, would not come with the same aggregated usage length as tubes or pipes with heavy-walled materials, although both have the same materials.

5. Available space versus necessary length to absorb motion

The kind of vibration, offset motion, motion, as well as necessary length to absorb them, are all the important things to take-into-account in determining the right flexible hose for an application. To choose exact measurements for these conditions, it is advisable to refer to the offset chart provided by the manufacturer before you make the final purchase decision.

6. Type and amount of motion

The flexible hose is designed for a variety of applications in mind. These include:

– Excessive vibrations and motions; 
– Misaligned pipes or tubes;
– Necessary flexibility for manual handling tasks 

To choose the right type of flexible hose for those applications, it is essential to carefully consider the inherent versatility and flexibility of their materials in relation to the expected usage, installation, and assembly.

7. Fittings to connect with the existing connections

End fittings might come with a female or male thread. In addition to standard unions such as flanges or flared tube models, customized connectors and special designs are also available on the market. The method of attachment like mechanical, silver brazing, soldering, or welding, is primarily determined by the proper kind of alloy and hose. In general, it is best to contact the manufacturer if you want to have any customized fittings.
