The application of copper slag in water jet cutting is mainly reflected in its characteristics and advantages as an abrasive.

The following are the specific applications of copper slag in water jet cutting technology and its advantages.
1. Overview of Water Jet Cutting Technology
Water jet cutting is an efficient cutting process that uses high-pressure water jets to cut a variety of materials. The process is generally divided into two types: pure water jetting and abrasive water jetting. For the cutting of hard materials, abrasive water jetting is a common method, in which the water stream is mixed with an abrasive (such as copper slag) to enhance the cutting ability.
2. Advantages of copper slag as an abrasive
High density and hardness
Copper slag has a density of about 3.4 g/cm³, with high hardness and strong cutting ability. This allows copper slag to effectively penetrate a variety of materials, including metals and concrete, in water jet cutting, and is particularly suitable for the processing of large structures such as offshore platforms and pipelines.
Quick cleaning and high efficiency
When copper slag is used as an abrasive, its sharp particles can act on the surface of the workpiece with higher impact force, and copper slag can remove rust, corrosion and other impurities faster than traditional abrasives. This fast cleaning ability is particularly important for industrial applications that require high efficiency and large-scale processing.
Environmental protection and recyclability
Copper slag has less impact on the environment during use and can be recycled and reused. Compared with traditional abrasives, copper slag produces less dust during sandblasting and is less harmful to workers’ health and the environment.
3. Specific application scenarios
Marine structure cutting
In marine engineering, copper slag abrasives are widely used in water jet cutting to process structures such as submarine pipelines and platforms. Its high density enables it to effectively cut hard materials, thus meeting the precision and strength requirements of marine engineering.
Oil and gas pipeline cleaning
Copper slag is also used in the oil and gas industry, especially when cleaning oil and gas pipelines. Its strong grinding ability can quickly remove thick layers of dirt and corrosion on the inner wall of the pipeline, ensuring the safe operation of the pipeline.
Metal surface treatment
In the metal processing industry, copper slag abrasives are used to clean metal surfaces and prepare for subsequent coating or treatment. It effectively removes old paint, rust, etc., making the metal surface smooth and flat, and improving the quality of subsequent processes.
4. Summary
The application of copper slag in water jet cutting demonstrates its importance as an efficient, environmentally friendly and economical abrasive. With the development of technology, the scope of use of copper slag will be further expanded to provide better services for various industries. At the same time, the rational use of this industrial by-product will also help to achieve sustainable resource utilization and environmental protection.

The application of copper slag in oil pipe cleaning has significant advantages, which are mainly reflected in the following aspects:
1. Efficient cleaning ability
The characteristics of copper slag as an abrasive enable it to perform well in oil pipe cleaning. Its sharp particles can effectively remove rust, dirt and other impurities on the inner wall of the oil pipe, ensuring that the pipeline maintains good fluidity and safety. Compared with traditional cleaning materials, the high density of copper slag (about 3.4g/cm³) enables it to generate stronger impact force during the cleaning process, thereby accelerating the cleaning speed.
2. Reduce dust generation
During the oil pipe cleaning process, copper slag produces less dust than other abrasives (such as sand). This is because copper slag has a free silica content of less than 0.1%, which not only helps keep the work environment clean, but also helps improve worker visibility and reduce health risks14. This low dust characteristic greatly improves the safety of working in closed or confined spaces.
3. Durability and economy
The hardness of copper slag is between 6 and 7 on the Mohs hardness scale, which means it can be reused many times without losing its grinding effect. This durability makes the use of copper slag for oil pipe cleaning more economical than using other abrasives, because less material consumption is required for the same cleaning effect, thereby reducing overall costs.
4. Environmental characteristics
Copper slag is a by-product of the smelting process, and its use as an abrasive helps to reuse resources and reduce waste emissions. Due to its environmental characteristics, copper slag is considered a sustainable option that helps reduce the need for new raw materials while reducing environmental impact.
5. High-quality surface treatment
After using copper slag for oil pipe cleaning, the inner wall of the pipe will be left with a smooth and clean surface, which is very important for subsequent coating or treatment. Copper slag provides precise and high-quality cleaning, making the oil pipe more reliable in subsequent use.
6. Wide range of applications
In addition to oil pipe cleaning, copper slag can also be used for sandblasting of other metal surfaces, concrete surface cleaning and many other industrial applications. This versatility makes copper slag popular in the industry and an ideal abrasive.
Copper slag can effectively remove many types of dirt in oil pipe cleaning, including the following categories:
1. Rust
Copper slag has strong grinding ability and can quickly remove rust on the inner wall of the oil pipe. This rust is usually caused by the pipe being exposed to a humid environment or not being used for a long time. The sharp particles of copper slag can penetrate the rust layer to ensure that the metal surface is smooth again.
2. Dirt and sediment
During the use of oil pipes, various dirt and sediments will accumulate inside, including grease, dust and other impurities. Using copper slag for sandblasting can effectively remove these dirt and maintain the fluidity and efficiency of the pipe.
3. Old coatings
Many oil pipes are treated with anti-corrosion coatings before use, but over time, these coatings may peel off or fail. Copper slag can effectively remove the old coating and provide a good adhesion foundation for the subsequent new coating, ensuring the effect and durability of the new coating.
4. Corrosives
In addition to rust, oil pipes may also be affected by other types of corrosives, such as chemical corrosion or microbial corrosion. The grinding properties of copper slag enable it to handle these stubborn corrosives and restore the integrity of the pipeline.
5. Welding residues
During the manufacturing and maintenance of oil pipes, welding may produce residues such as welding spatter and slag. Copper slag can effectively remove these welding residues, making the surface of the pipeline flat and smooth, which is helpful for subsequent processing and maintenance.
6. Other impurities
In addition, there may be other types of impurities in the oil pipe, such as dust, sand, etc. If these impurities are not cleaned in time, they will affect the normal operation of the pipeline. Copper slag can quickly remove these impurities during the sandblasting process and improve work efficiency.
Summary
In short, copper slag has a wide range of applications in oil pipe cleaning, and can effectively remove rust, dirt, old coatings, corrosives, welding residues and other impurities. These advantages make copper slag an ideal cleaning material in the oil and gas industry, helping to improve equipment safety and operating efficiency.
