Rules for the inspection of fire hoses

Fire hose is an indispensable equipment in fire fighting, and its quality is directly related to the effect and safety of fire fighting. In order to ensure the quality of fire hose, the following inspection rules:

1. appearance inspection

The appearance of the fire hose shall be straight, without obvious distortion, deformation or damage. The surface of the water belt should be smooth, uniform color, no obvious color difference. In addition, the interface part of the hose should also be checked to ensure that it is tight, not loose, and closely matched with the hose body.

2. length inspection

The length of the fire hose should meet the national standard, and the error should be within the allowable range. During inspection, special measuring tools shall be used to measure the length along the hose axis to ensure that the actual length of the hose is consistent with the marked length.

3. pressure inspection

Pressure inspection is the key link to evaluate the performance of fire hose.

1. On the professional test equipment, gradually increase the pressure and observe the reaction of the water belt.
2. Check the deformation of the water strip under high pressure to ensure that it does not rupture or leak under the specified pressure.
3. Observe the interface performance of the water belt under pressure to ensure that there is no leakage or looseness.

4. material inspection

Fire hose material should have good fire resistance, stretch resistance and wear resistance. During inspection, the quality of the material can be evaluated by observation, touch and necessary physical tests.

Functional inspection of 5.

Test the water flow of the water belt to ensure that the water belt is filled with water and the water flow is smooth and unobstructed. At the same time, check the torsion resistance of the water belt to ensure that it does not
