I Sandblasting hose Selection of

Proper selection of hoses can ensure the safety and rationality of the whole system. The following points should be noted:

1. Select according to the system pressure Sandblasting hose High pressure and many layers of steel wire. Each hose has a working pressure. Therefore, according to the actual system pressure, the working pressure of the selected hose is greater than the actual working pressure.

2. Select the inner diameter of the hose according to the flow. If the pipe diameter is too small, it will increase the flow rate of the medium in the hose, make the system heat up, reduce efficiency, generate excessive pressure drop, and affect the performance of the entire system. If the diameter of the hose is too large, the cost will increase. Therefore, when the inner diameter of the hose is fixed with a pipe clamp or the hose passes through a spacer such as a steel plate, the outer diameter of the hose should also be noted.

3. When selecting the high-pressure hose, pay attention to the bending radius of the high-pressure hose. When calculating the bending radius, the pressure length of the front joint shall be subtracted. If the bending radius of the installed hose is too small, the bearing capacity of the hose will be reduced and its service life will be affected.

4. Select the connector type reasonably according to the hydraulic configuration, such as SAE flange connector, internal thread connector or external thread connector, 90, 45 and other connector angles, and the overall hose assembly angle.

II Sandblasting hose deposit.

1. The storage place of upper and lower hoses shall be kept clean and ventilated, with relative humidity and storage place temperature. The hoses shall be protected from direct sunlight and water.

2. If Sandblasting hose It must be leveled temporarily in the open air, Sandblasting hose It must be placed flat and flat, and the bottom shall be padded and the top shall be covered, and no heavy objects shall be piled up; At the same time, Sandblasting hose Do not contact with heat sources.

3. Storage Sandblasting hose They shall be placed separately according to different varieties and specifications, and shall not be mixed and stacked, and management cards shall be hung.

4. When storing the hose, both ends of the hose must be sealed firmly to prevent sundries from entering the hose.

5. Hoses shall be stored in a loose state as far as possible. Generally speaking, hoses with small inner diameters can be rolled up for storage.

6. In order to prevent the pipeline from being compressed and deformed during storage, the stacking should not be too high, and the pipeline should be stacked frequently during storage, at least once a quarter.

7. Storage Sandblasting hose Do not touch acids, alkalis, oils, organic solvents or other corrosive liquids and gases, and stay 1 m away from the heat source.

8. During storage, it is strictly prohibited to stack heavy objects on the pipe body to prevent external extrusion and damage.

nine Sandblasting hose During storage, it should be used for a long time to avoid the impact of too long storage Sandblasting hose Quality.
