(1) Pressure: The intensity of destroying and removing dirt, representing the striking strength and capability. The harder the dirt, the higher the pressure required. The dirt on the inner walls of oil field production pipes and water wells typically requires 700bar to 1400bar. Through our tests, operating at a high pressure of 1400bar and a running pressure of 1350bar can meet the destructive force requirements for cleaning and paraffin removal in almost all scaling pipes.

(2) Flow Rate: Factors include scrubbing capability and impact frequency. The higher the flow rate, the greater the cleaning efficiency. Through our experiments and practices, under a pressure of 1350bar, a flow rate of 44L/min ensures simultaneous operation of 8 nozzles, increasing the rotating cleaning surface. Time: The longer the time, the higher the cleaning frequency, and the better the cleaning efficiency. Requirement: 2 minutes per piece, equivalent to 4 seconds per pipe for up and down, 60 seconds forward and 20-40 seconds backward for other 10-meter long pipes, approximately 0.18 meters per second, 8-nozzle ultra-high-pressure jet rotation cleaning, with a requirement for speed greater than or equal to 420rpm, adjustable.

(3) Temperature: Temperature can melt and disperse the structure of grease-like dirt, making it loose and fluid, which is easy to remove. Generally, a 1350bar water jet produces about 30~40°C of jet friction heat. There is no problem with simultaneous cold cleaning, descaling, and wax removal. However, under environmental temperatures of 0~15°C, it is very difficult to perform cold cleaning, descaling, and wax removal. In an environment of -50~0°C, using cold water is even more impossible. Typically, when working below 15°C, the water temperature needs to be heated to maintain between 15~20°C, but the wax removal temperature must be above 30°C.

(4) Jetting Method: The cleaning capability and efficiency are maximized by the comprehensive factors of jet distance, jet angle, and nozzle quantity. This proposal utilizes jingcheng (Jingcheng) diamond nozzles, with 8 water jets at a diagonal angle of 45 degrees forward.
