  • Caustic Corrosion - an overview | ScienceDirect Topics

    10/2/2011 · According to the pH monitoring data of the process water, especially at site II and III, the QO/DS heat exchanger tubes had been subjected to an over alkaline (pH > 9.5, even reached 11.5) environment for a long time. Consequently, caustic corrosion (called caustic embrittlement more accurately, a specific kind of stress corrosion cracking) was engendered on the carbon steel tubes …

    Proper treatment of boiler feedwater effectively protects against corrosion of feedwater heaters, economizers, and deaerators. The ASME Consensus for Industrial Boilers (see Chapter 13) specifies maximum levels of contaminants for corrosion and deposition control in boiler systems. The consensus is that feedwater oxygen, iron, and copper

  • Boiler explosion - Wikipedia

    A boiler explosion is a catastrophic failure of a boiler. There are two types of boiler explosions. One type is a failure of the pressure parts of the steam and water sides. There can be many different causes, such as failure of the safety valve, corrosion of critical parts of the boiler, or low water level. Corrosion along the edges of lap
