Tips for choosing the right hose

Below are some features to consider when choosing a hose.

1. Type of installation

The choice of a flexible hose is always related to the pressure of the circuit to be connected, the work cycles, continuous or with water hammer, the inner diameter of the hose and the type of fluid.

2. Working pressure

According to EN, UNI ISO, DIN and SAE standards, the recommended working pressure ratio is 1:4.

3. Chemical resistance

The hose must be compatible with the external factors to which it will be exposed, such as ozone, sunlight, water, oils, and other atmospheric agents.

4. Water hammer

In installations where water hammer occurs (sudden pressure increases caused by a rapid change in the flow rate of the pipe), it is necessary to choose a flexible hose that can increase the safety factor. Otherwise, a minimum safety factor is sufficient.

5. Operating temperature

The temperature indicated on each hose is the maximum for the fluid passing through it, although they can tolerate higher temperatures for short periods of time.

It should be noted that constant work under maximum temperature reduces the durability of the hose.

6. Volumetric expansion

According to national and international standards.

7. External temperature

Excessive heat or cold near the hose could damage the outer coating and reinforcement, reducing its durability.

8. Gaseous fluids

In gaseous environments under high pressure, selecting the correct hose is crucial. Therefore, increasing the safety factor is advisable.
