Hose Selection Guide: How to Choose the Right Hose for You

First, the choice of hose

Hose is one of the key components connecting fittings and liquid or gas, widely used in agricultural machinery, engineering machinery, construction machinery, ships, automobiles and other industries. The quality of the hose has a vital role in the normal operation and safety of mechanical equipment. Therefore, you need to know the following issues when you buy hose:

1. Material of hose

There are many kinds of materials for hose, mainly rubber, polyurethane, polyester, PTFE and so on. Different materials of the hose in the applicable industry, service life, operating temperature range and pressure resistance and other aspects of the differences, so you need to choose the hose suitable for their own working environment.

2. Working pressure of hose

The working pressure of a hose is related to the strength of its material, which is usually determined by its inner diameter and wall thickness. When purchasing a hose, you need to do adequate pressure tests to ensure that it has sufficient strength and pressure resistance.

3. Inner diameter of hose

The inner diameter of a hose is directly related to its flow characteristics. When choosing a hose, you need to choose a suitable inner diameter according to the actual needs, according to the required flow and pressure and other parameters.

4. Bending radius of the hose

In operation, the hose needs to pass through some bending position, so the bending radius of the hose is also one of the key factors to be considered in the selection process. The hose with a small bending radius is not suitable for bending use, otherwise cracking may occur and the life will be shortened.

Second, which hose is good to use without bending

For hoses, bending is an essential part of their work. But what hose is good to use without bending? Let's take a look:

1. polyurethane hose

Polyurethane hose is mainly used in air transmission, gas transmission, liquid transmission and other fields. Because of its great elasticity, there will be flanging, delamination, damage and other phenomena in the bending process, so it is not suitable for bending use.

2. PVC hose

Relative to other materials, PVC hose has a small bending radius and better softness, but its mechanical properties are poor, easy to crack, aging and other phenomena, so it is not suitable for bending use.

Third, how to maintain the hose

After selecting a good hose, it is also important to maintain its maintenance to extend the service life of the hose. Here are some maintenance methods:

1. Clean the hose regularly to avoid contamination affecting its performance.

2. Check the surface of the hose for cracks, aging, deformation, etc., and replace it in time if found.

3. Avoid repeated bending or excessive stretching when using the hose to avoid affecting its strength.

In short, when purchasing hose, you should choose the right hose for you according to the actual situation, and you also need to do the corresponding maintenance work to ensure the normal operation and safety of the hose.
