An Overview of Chemical High Pressure Water-jetting Technology
Water-jetting technology is an established technique used to clean and remove resistant coatings, corrosion and scale from surfaces. In the past, these operations were carried out by manual methods, or low-pressure “jet wash” systems. In the 1980s, advances in technology allowed for the development of advanced, high-pressure chemical water-jetting equipment.
In conventional high-pressure water-jetting, pure water is used to remove coatings and materials from the surface of a hard substrate, such as a ship’s hull or metal structure. In chemical high-pressure water-jetting, a chemical solution is added to the pure water as it is pumped under high pressure through the nozzle. This combination produces a powerful cutting and cleaning action capable of removing hard-to-remove materials and coatings. The combination of chemicals with the high-pressure water jet substantially reduces the amount of time needed to complete a cleaning or material removal task compared to conventional high-pressure water systems.
The main advantage of chemical high-pressure watejetting is its effectiveness in removing hard-to-remove substances, such as rust, oil, grease, corrosion, scale and debris. In addition, chemical water-jetting can be used to quickly remove coatings from surfaces without damaging the substrate. This allows for the rapid and effective preparation of new surfaces for painting or other finishing processes. Additionally, chemical water-jetting does not create airborne particles or residual waste materials, reducing the potential for air pollution and making it more environmentally friendly than other coating removal techniques.
Chemical water-jetting systems consist of a pump, nozzle, hose, and chemical solution. The pump contains a system of filters to ensure that the water and chemical solution is clean and free of foreign objects. A variety of nozzles are available to suit the particular needs of the application, including one-piece and multi-piece nozzles. The hose is designed to allow the high pressure water and chemical solution to travel safely through the system to the nozzle. The chemical solution is typically a concentrated solution of detergents, solvents and other cleaning agents, depending on the particular application.
Chemical high-pressure water-jetting technology is used in a variety of industries, including offshore oil and gas, shipbuilding and repair, industrial cleaning, and production operations. The technique is particularly well suited for applications such as cleaning horizontal surfaces, vertical surfaces and around pipe fittings. It allows for the safe and effective removal of unwanted coatings and materials without damaging the substrate.
In conclusion, chemical high-pressure water-jetting technology is a cost-effective and environmentally friendly solution for a wide range of cleaning and coating removal applications. By combining the action of high-pressure water with a specialized chemical solution, it is capable of quickly and effectively removing hard-to-remove material from a variety of surfaces. This makes it an excellent choice for a variety of industries and operations.
