Corrosion or corrosion protection is a complex of structural and construction measures intended to prevent corrosion. Polyurea coating protects against corrosion. The physical aging process destroys any product from the very first moment. The manifestations of corrosion are so numerous and varied that the war against it is still relevant today.
All structural materials are corroded: metals, polymer materials, silicates and all that is made of them: buildings and structures, ships and offshore structures, bridges and tunnels , underground and underwater pipes, oil and gas storage, urban underground utilities, energy equipment, agricultural buildings. During operation, the surfaces of these structures are inevitably exposed to moisture, pollution, ultraviolet radiation or aggressive environments. Sun, air and water are the main catalysts for continuous corrosion.
Nearly a third of the world’s produced metal is destroyed by corrosion and a tenth of it is lost forever. About 70% of accidents and equipment damage happen because of this. An element of surprise always occurs when these hazards occur, due to the reduction in the device wall thickness and in particular the change of the material’s mechanical properties due to corrosion which is difficult to control and execute. the strongest in uncontested places. Virtually all types of corrosion are detected only at the time of emergency structure destruction, formation through trauma of the walls of the equipment and pipes. Direct and indirect economic losses due to monetary corrosion are equivalent to 2-4% of the developed countries’ gross national product. The practical development and use of effective anti-corrosion measures and structural protection not only allows for reduced metal loss and structural load-bearing capacity, but also reduces the material consumption of buildings. , increase their load and reduce fuel and energy consumption during operation, increasing the life of the facility. All of this generally helps to reduce costs and increase the profitability of the project.
Polyurea are very corrosion resistant thanks to their high chemical and wear resistance … Polyurea are successfully used to protect main pipes, metal structures, vehicle tanks, tanks, pump stations and equipment.
