摘要：通过对铸石管材与常用煤气管材Q２３５和球墨铸铁材质的耐酸、碱、盐腐蚀试验，得出铸石管材耐蚀性远远高于常用金属管材的结论，认为在耐蚀性方面，铸石管材可以代替金属管作为煤气的输送管道。

Abstract：The paper analyzed the corrosion resistance of cast stone pipeline and the commonly-used Q２３５ and ball graphite cast iron in acid or alkali or salt liquor． The test results show that the corrosion resistance of cast stone pipeline is remarkably higher than that of commonly-used metal．Therefore，cast stone pipeline may replace metal tubes as the coal gas transportation corrosion-resistance pipes．
Key words：cast stone pipe； metal coal gas pipeline； corrosion resistance |
