What are the precautions for the use of dredging hose

Due to the complex varieties, diverse structures and different service conditions of dredged hoses, the service life of dredged hoses depends not only on the quality, but also on the correct use and maintenance. Therefore, even if the product has extremely high quality, if it can not be used and maintained correctly, it will seriously affect its service quality and service life, cause undue serious accidents and cause losses to property. The following points shall be noted:

1. The dredging hose and dredging hose assembly can only be used to transport the designed materials, otherwise it will reduce the service life or failure.

2. The length of dredged rubber hose shall be used correctly. The length of dredged rubber hose changes (- 4% - + 2%) under high pressure and the length changes caused by mechanical movement.

3. The dredging hose and dredging hose assembly shall not be used under the pressure (including impact pressure) exceeding the design working pressure.

4. The temperature of the medium conveyed by the dredging hose and the dredging hose assembly shall not exceed - 40 ℃ - + 120 ℃ under normal conditions, otherwise the service life will be reduced.

5. The dredging hose and the dredging hose assembly shall not be used under the small bending radius of the dredging hose, so as to avoid bending or bending near the pipe joint, otherwise it will hinder the hydraulic transmission and conveying of materials or damage the dredging hose assembly.

6. The dredged hose and dredged hose assembly shall not be used under torsion.

7. The dredged hose and dredged hose assembly shall be handled carefully, and shall not be dragged on sharp and rough surfaces, bent and flattened.

8, the dredging hose and dredging hose assembly should be kept clean, and the interior should be rinsed clean (especially acid conveying pipes, spray pipes and mortar pipes).

9. The dredged hose and dredged hose assembly that exceed the service life or storage period shall be tested and identified before they can be used again.
