The continuous updating of technology has led to the development of products in the process of continuous updates and upgrades. At present, the inspection requirements for rubber hoses have also been improved compared to before.


Inspection indicators for ultra-high pressure rubber hoses


According to the safety regulations for high-pressure water jet cleaning operations, high-pressure hoses should meet the following indicators:


1) The blasting pressure should reach more than 2.5 times the working pressure.


2) The test pressure should reach 1.5 times the working pressure and be maintained 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 with a working pressure of 1000-2800bar is 15 times/min, and above 2800bar, it is 110 times/min.


Due to the widespread application of high-pressure cleaning machines in various industries, and the relatively worst working conditions of high-pressure hoses, we must pay attention to quality when purchasing high-pressure hoses to avoid unnecessary safety accidents.
