4 Advice to Choose a Industrial Flex Hose

Here are essential considerations for selecting the right hose for your needs.

1. Installation Type

The appropriate selection of a flexible hose heavily depends on factors such as the pressure of the system to be connected, operational cycles—whether continuous or subject to sudden pressure surges—and the internal diameter along with the type of fluid it will carry.

2. Operating Pressure

According to established guidelines (EN, UNI ISO, DIN, and SAE), the ideal working pressure ratio for hoses is generally 1:4.

3. Chemical Compatibility

Ensure that the hose material is resistant to external elements it will encounter, including ozone, UV rays, water, oils, and various atmospheric conditions.

4. Avoiding Water Hammer

In systems that experience water hammer (a sudden increase in pressure from a rapid change in flow), it is crucial to select a flexible hose designed to handle increased safety factors. A minimal safety factor may suffice in other scenarios.

5. Temperature Regulations

Each hose indicates the maximum temperature for the fluid it can carry; although short spikes above this limit can be tolerated, prolonged exposure at this temperature can shorten hose life.

6. Volume Expansion

Refer to national and international standards for guidance.

7. Environmental Temperature

Excessive heat or extreme cold can damage the exterior and reinforcement of the hose, ultimately impairing its longevity.

8. Gaseous Fluids

In environments containing gases under high pressure, the right hose selection is vital. It's advisable to apply a higher safety coefficient in such cases.
