Refractory coated iron-based pipe |
摘要 |
A thermally stable refractory coating for iron-based piping and a method of forming the same is provided. The refractory coating comprises from about 30 to about 35 weight percent sodium silicate; from about 31 to about 36 weight percent course silica, about 80 to about 200 mesh; from about 12 to about 16 weight percent fine silica, about 325 to about 400 mesh; from about 1 to about 6 weight percent hydrated aluminum silicate clay; from about 1 to 4 weight percent graphite; from about 0.8 to about 0.9 weight percent sodium aluminate; and, from about 3 to about 5 weight percent magnetite M.S-200. The invention also concerns a method of forming the above-described coating on iron-based piping.
