摘　　要：对所取锅炉炉管材料进行了宏观检察、化学成分、壁厚与管径测量、光学金相组织、X射线、常温力学性能、断口扫描电镜、能谱元素等试验分析 ,结果表明锅炉炉管材料的局部腐蚀主要是氧化 -氯化腐蚀。强度校核表明 ,该段炉管目前的壁厚能够满足压力P =17 2MPa ;温度T =35 4℃的使用条件。A boiler pipe was analysed by means of macro-morphology, chemical composition, measurement of wall thickness and diameter, optical microscope, X-rays, mechanical properties, scanning electron microscope(SEM) and EDS in this paper.The results showd that the corrosion of the boiler pipe materials was a partial oxidation and chlorination corrosion. Strength proof showed that the wall thickness of boiler pipe can be used in the following designing condition, P=17.2 MPa and T=354 ℃.
