The inspection of high pressure hose is the main process to determine whether it has practical market value

The clauses in the inspection objectives of the ultra-high pressure hoses are formulated in relevant parts
According to the rule requirements of the "High Pressure Water Jet Cleaning Safety Standard", the high pressure hose should reach the following target requests:
1) The explosion pressure should reach more than 2.5 times the working pressure.
2) The experimental pressure should reach 1.5 times the working pressure, and adhere to this pressure for more than 2 minutes without damage.
3) Pulse pressure should be in the range from zero to working pressure, 50,000 pressure pulses without damage; The pulse frequency is 15 times /min when the working pressure is 1000-2800bar, and 110 times /min when the working pressure is above 2800bar.
Because high-pressure cleaning machines are now widely used in all walks of life, and the working conditions of high-pressure hoses are relatively the worst, it is necessary for us to pay attention to quality when purchasing high-pressure hoses, and then prevent unnecessary safety accidents.
In the process of using the ultra-high pressure cleaning machine, there are many factors that affect the service life of the ultra-high pressure hose. In addition to the technical level of the hose in the manufacturing process, the quality function of the inner layer and the joint, the accurate selection and application of the ultra-high pressure hose and many other factors have a great impact on the service life of the ultra-high pressure hose.
