1. The high-pressure oil pipe and oil pipe assembly can only be used within its bearing range, and should not be used under pressure exceeding the designated working pressure.
2. The high-pressure oil pipe and the oil pipe assembly should be transported carefully, and should not be dragged on sharp or rough ground, nor should the high-pressure oil pipe be bent or crushed.
3. The temperature of the medium transmitted by the high-pressure oil pipe and the oil pipe assembly should not exceed minus 40 degrees Celsius to 120 degrees Celsius, otherwise its life will be shortened.
4. The high-pressure oil pipe and oil pipe assembly should not be used under the condition of the small bending radius of the high-pressure oil pipe. Try to avoid bending or bending near the pipe joint. Otherwise it will prevent hydraulic transmission and transport materials or damage the high-pressure oil pipe assembly.
5. The high-pressure oil pipe and the oil pipe assembly should be kept clean, and the interior should be cleaned to prevent foreign matter from entering and damaging the equipment.
