铸铁管 用铸铁浇铸成型的管子。铸铁管用于给水、排水和煤气输送管线，它包括铸铁直管和管件。按铸造方法不同，分为连续铸铁管和离心铸铁管，其中离心铸铁管又分为砂型和金属型两种。按材质不同分为灰口铸铁管和球墨铸铁管。 连续灰口铸铁管的公称口径为75～1200毫米，直管长度有4米、5米及6米;按壁厚不同分LA、A和B三级。砂型离心灰口铸铁管的公称口径为200～1000毫米,有效长度有5米及6米；按壁厚不同分P、G两级。 球墨铸铁管与灰口铸铁管相比，强度大、韧性好、管壁薄、金属用量少、能承受较高的压力，是铸铁管材的发展方向。 管与管之间的连接，采用承插式或法兰盘式接口形式；按功能又可分为柔性接口和刚性接口两种。柔性接口用橡胶圈密封，允许有一定限度的转角和位移，因而具有良好的抗震性和密封性，比刚性接口安装简便快速，劳动强度小。
