Self-floating hose is a piping system used for drainage, sewage or irrigation, which is widely used in various fields. In order to ensure the safety of self-floating hoses, regular testing and maintenance are necessary. Here are some ways to check the safety of self-floating hoses:

1. Visual inspection: Visual inspection is the easiest way to detect the safety of self-floating hoses. Check the surface of the hoses for cracks, deformation, wear, etc., and whether there is any leakage at the pipe connection.

2. Stethoscope inspection: Use a stethoscope to hear the sound of water flow in the self-floating hose and whether there is any abnormal sound. If there is an abnormal sound, it may mean that the hose is damaged or leaking.

3. Instrument inspection: Various instruments can be used to inspect the safety of self-floating hoses, such as sonar, ultrasonic, radar, etc. These instruments can detect defects and leaks inside the hose, as well as the shape and size of the hose.

4. Maintenance records: regular records

maintenance status, including maintenance time, content, results, etc. These records can help to detect the safety of self-floating hose and discover potential problems in time.

5. Simulation experiment: The simulation experiment can simulate the situation of the self-floating hose in actual use and test the safety of the pipeline. For example, simulate parameters such as water flow, pressure, and temperature in the pipeline, as well as external pressure and impact on the pipeline.

In short, these methods can help to discover potential problems in time, and take corresponding measures for maintenance and repair, so as to ensure the safety of self-floating hoses.
