  • The hazard of oxygen corrosion in steam boilers

    2019-3-15 · Nowadays, steam boilers are widely used in various fields. However, the use of steam boilers for a long time will cause oxygen corrosion. Although the current anti-corrosion technology and control of boiler pollution have improved, the oxygen corrosion problem of steam boilers has been improved to some extent. However, oxygen corrosion has not yet been fundamentally solved.
