Device for thermal electric and nuclear power plants

摘要

For the purpose of preventing reductions of wall thickness due to erosion-corrosion in parts (2, 3, 7) of a system made of carbon steel, and which constitute a wet steam system, a feedwater and condensate system, and a drain system of a thermal or nuclear power plant, a coating (17) of metal or ceramic which is chemically stable against a fluid flowing in the systems is formed by spraying on the surface of the devices which are exposed to the fluid.
