1. Ensure the correct selection and matching of flanges and hoses

Choose appropriate flange and hose materials:

Choose appropriate flange and hose materials according to the characteristics of the medium (such as temperature, pressure, and corrosiveness) to ensure that they can adapt to the working environment.

Choose gaskets that match the flange and hose materials to enhance the sealing performance.

Ensure the matching of flanges and hoses:

Ensure that the flange type, sealing surface type and gasket type match each other to avoid leakage caused by mismatch.

2. Strictly control the installation process

Optimize the assembly process:

Strictly follow the standards to assemble the flange to ensure that the connection between the flange and the hose is firm and reliable.

Use professional tools and equipment for installation to avoid damage during installation.

Check the installation quality:

After the installation is completed, check the connection between the flange and the hose to ensure that there is no looseness, misalignment or damage.

Perform a pressure test to verify the sealing performance of the flange and the hose.

3. Strengthen daily maintenance and inspection

Regular inspection:

Regularly inspect flanges and hoses, including checking the tightness of flanges, wear and aging of hoses.

Check whether the gasket is intact and whether it is deformed or damaged.

Timely replacement:

When the flange or hose is found to be worn, aged or damaged, it should be replaced in time.

The replacement cycle of the gasket should be determined according to the actual situation to avoid the failure of the gasket due to long-term use.

4. Deal with special working conditions

Reduce the impact of vibration:

Add shock absorbers at the connection between flanges and hoses to reduce leakage caused by vibration.

Improve the pipeline support structure to ensure the stability of the pipeline.

Deal with medium corrosion:

For corrosive media, choose corrosion-resistant materials or coatings to protect flanges and hoses.

Regularly check the corrosion situation and take timely measures to prevent the corrosion from worsening.

Consider thermal expansion and contraction:

Set a compensation device at the connection between flanges and hoses to deal with the thermal expansion and contraction of the fluid medium.

Regularly check the working condition of the compensation device to ensure its effectiveness.

In summary, preventing flange hose leakage requires multiple aspects, including ensuring the correct selection and matching of flanges and hoses, strictly controlling the installation process, strengthening daily maintenance and inspection, and responding to special working conditions. The implementation of these measures will help improve the reliability and safety of flange hoses.
