Inquisition into Approach to Retard the Creation and Exfoliation of Oxide-layer inside Hot Pipes

Shen Minguang (Zhejiang Thermal Power Construction Company, Hangzhou, 310016)  
In some power plants because oxidized layers inside the hot pipes is exfoliated from the wall and accumulated inside, the steam flow would be decreased greatly. As a result, the great temperature rise accelerates the metal creeping under high pressure and enlarges the size of pipe, the pipe burst occurs finally. Focusing on the mechanism of creation and development and rules of oxide layers, the approaches are discussed to retard and relax the exfoliation from the wall.
