With the continuous updating of technology, the products are also developing in the continuous updating. at present Sandblasting hose The inspection requirements of are also improved.

Ultrahigh pressure Sandblasting hose Inspection index of

According to the requirements of Safety Specification for High Pressure Water Jet Cleaning, the high pressure hose shall meet the following index requirements:

1) The bursting pressure shall be more than 2.5 times of the working pressure.

2) The test pressure shall be 1.5 times of the working pressure, and the pressure shall be kept for more than 2 minutes without damage.

3) Pulse pressure shall be within the range from zero to working pressure, and 50000 pressure pulses shall be free of damage; The pulse frequency is 15 times/min when the working pressure is 1000-2800bar, and 110 times/min when the pressure is above 2800bar.

As the high-pressure cleaning machine has been widely used in all walks of life, and the working condition of high-pressure sand blasting hose is relatively the worst, we must pay attention to the quality when selecting high-pressure hose, so as to avoid unnecessary safety accidents.
