1. Characteristics and Cleaning Difficulties of Pipe Fouling in Petroleum Industry
Industrial pipelines in the petroleum industry transport crude oil, refined oil, and chemical media for a long time. The inner walls are prone to accumulating oil stains, wax, scale, and sediment. These deposits have strong adhesion, complex composition, and are difficult to strip, which is a major problem in industry operation and maintenance. The main cleaning difficulties are reflected in: diverse pipeline diameters (DN300–DN800), some laid in the field, requiring high mobility of equipment; uneven fouling thickness, some up to 5–15cm, which is difficult to clean thoroughly with ordinary cleaning methods; diverse materials (carbon steel, stainless steel, etc.), requiring avoidance of tube wall damage during cleaning to prevent leaks and safety accidents, and high requirements for long-term cleaning effect.

2. Selection Guide for Pipeline Cleaning Equipment in Petroleum Industry
The selection should focus on the three cores of "adaptability, long-term effect, and safety", focusing on three points: first, priority is given to small mobile equipment, which is convenient for cleaning pipelines in the field and different positions; second, pressure and flow rate matching, covering 500bar–2800bar pressure and 20–110L/min flow rate, ensuring sufficient jet penetration to strip thick scale; third, safety compliance, with pressure overload protection function, operating noise below 85 decibels to ensure the safety of operators. In addition, the equipment must have a water-saving function to reduce water consumption and operation and maintenance costs, adapting to environmental protection requirements.
3. Long-Term Cleaning Advantages and Industry Applications
With high-speed water flow as power, high-pressure water jet can go deep into the pipeline, completely strip fouling without damaging the tube wall. After cleaning, the inner wall of the pipeline is smooth, reducing medium adhesion, achieving long-term cleaning, and reducing maintenance frequency. It has strong versatility, can adapt to petroleum pipelines of different diameters and materials, is easy to operate and can be quickly deployed, adapting to field operations and emergency maintenance needs, shortening shutdown maintenance time, ensuring the stable operation of the petroleum transportation process, and becoming the core equipment for long-term cleaning of pipelines in the petroleum industry.
