Cause Analysis and Countermeasures for External Corrosions of Overhead Gas Lines in Baotou Steel

In the paper,a variety of reasons for the corrosions of overhead gas lines are analyzed and the specific solutions are proposed combined with the situations for external corrosions of overhead gas lines in Baotou Steel.Moreover,the solutions suitable for the zones with adverse external environment are summarized by comparing a lot of anticorrosive materials,combining with a variety of influencing factors and the effects of anticorrosive projects on external anticorrosive constructions for overhead gas lines in iron-melting and coking zones.
