Uncover SuperHigh pressure pipeReasons for service life, precautions for using ultra-high pressure pipes, and how to extend the service life of ultra-high pressure pipes.

(1) When installing and disassembling ultra-high pressure pipe joints, do not forcibly disassemble and tighten them. Threads of connecting threads shall be protected. At the same time, apply lubricating oil to the outer surface of the thread during installation, and protect the connecting thread with a protective sleeve after removal.

In addition, there are other factors that have a great impact on the service life of the ultra-high pressure pipe, such as the pressure fluctuation of the ultra-high pressure cleaner during the working process, and the fluid pressure fluctuation in the pipe caused by the instantaneous opening and blockage of the high-pressure spray gun and control valve.

(2) During the specific cleaning operation, try to avoid frequent opening and closing of the hand-held high-pressure spray gun to reduce the impact of pressure pulses on the hose and extend the service life of the hose. Special attention should be paid to the bending around the ultra-high pressure pipe joint. The joint should be coated with anti-rust oil to avoid contact with high temperature, high pressure and strong corrosive medium. When the actual pressure exceeds 1.25 times the specified pressure, the service life of the hose will be reduced by 50%. If you need to bend, ensure that the bending radius is not too small, generally not less than 15 times the outer diameter of the pipe, otherwise it will stretch the steel wire on the outside of the reinforcement layer and compress the steel wire on the inside, thereby reducing the compressive strength of the entire ultra-high pressure pipe and affecting the hose Service life.

1. Pressure matching

When using and selecting ultra-high pressure pipes, the hose with the appropriate pressure level should be correctly selected according to the working pressure of the ultra-high pressure cleaner. This can greatly extend the service life of the ultra-high pressure pipe. For example, the working pressure of the ultra-high pressure cleaner is 1200bar, and the ultra-high pressure pipe with a working pressure of 1800-2000bar should be selected. (6) When the ultra-high pressure pipe is not used for a long time, the internal water should be drained, and the hose should be bent into a roll and laid flat according to the specified size.

2. Path matching

Equipped with superHigh pressure pipeAt the same time, it should be selected according to the requirements of the ultra-high pressure cleaning machine host, because the pressure and flow of the ultra-high pressure cleaning machine have very strict regulations or restrictions, and the change of the pipe diameter will affect the working impact force of the high-pressure water jet front end and the balance of the system.

(1) In order to prevent accidents and injuries when the joint falls off or is damaged, the ultra-high pressure pipe should be equipped with a steel wire braided protective sleeve at the joint to connect the two ends. Therefore, it is recommended that when buying ultra-high pressure pipes, you should choose according to 1.5 times the working pressure.

(2) When the ultra-high pressure cleaner is working, the hose must not be twisted, and try to avoid bending. Experiments show that by replacing the ultra-high pressure pipe with a specified diameter of 5mm, the service life of the ultra-high pressure pipe with a diameter of 4mm is reduced to the original 1/3.

(3) When the ultra-high pressure cleaning machine is working, the ultraHigh pressure pipeIt shall not be crushed by heavy objects, bruised by sharp tools and bent. The outer layer shall be protected against excessive wear; the high-pressure pipe for suspension shall be firmly fixed at a short distance.
