høytrykksvannstrøm

Høytrykksvannstrøm, often referred to as hydrojetting or water blasting, is a cleaning and surface preparation method that utilizes extremely high-pressure water to remove contaminants. The water is propelled through specialized lances and nozzles at pressures typically ranging from 10,000 to 40,000 psi, and sometimes even higher. This immense force effectively dislodges and removes a wide variety of materials.

The applications of høytrykksvannstrøm are diverse. It is commonly employed for cleaning industrial equipment, pipelines, storage tanks, and heat exchangers. Paint, rust, scale, concrete, and other stubborn residues can be efficiently stripped away. In construction and civil engineering, it is used for concrete repair, surface preparation before coatings are applied, and the removal of old grout or sealants. The maritime industry utilizes it for cleaning ship hulls to remove barnacles and fouling.

Compared to dry blasting methods, høytrykksvannstrøm offers several advantages. It is a cleaner process as it generates no dust, making it suitable for indoor environments or areas with sensitive machinery. It also avoids embedding abrasive media into the cleaned surface, which can be a concern with some dry blasting techniques. Furthermore, the water itself can provide a rinsing action, leaving the surface clean. However, the high pressures involved require specialized equipment, trained operators, and careful consideration of safety protocols to prevent injuries. The process also generates wastewater that needs to be managed appropriately.
