高压锅炉管是锅炉管的一种，属于无缝钢管类别。制造方法与无缝管相同，但对制造钢管所用的钢种有严格的要求。高压锅炉管使用时经常处于高温和高压条件，管子在高温烟气和水蒸气的作用下，会发生氧化和腐蚀。要求钢管具有高的持久强度，高的抗氧化腐蚀性能，并有良好的组织稳定性。高压锅炉管主要用来制造高压和超高压锅炉的过热器管、再热器管、导气管、主蒸汽管等。中文名 高压锅炉管 外文名 High pressure

冶金工程介绍高压锅炉管是锅炉管的一种，属于无缝钢管类别。制造方法与无缝管高压锅炉管相同，但对制造钢管所用的钢种有严格的要求。高压锅炉管使用时经常处于高温和高压条件。高压锅炉管主要用来制造高压和超高压锅炉的过热器管、再热器管、导气管、主蒸汽管等。锅炉管由于长期在高温和高压条件下工作，材料将发生蠕变，塑性和韧性下降，原始组织改变，产生腐蚀等。作为锅炉用的钢管应具备：（1）足够的持久强度；（2）足够的塑性变形能力； （3） 最小的时效倾向和热脆性；（4）高的抗氧化、耐煤灰、耐天然气高温下腐蚀、蒸汽和应力腐蚀性能；（5）良好的组织稳定性以及良好的工艺性能。高压锅炉管的钢种有碳钢以及珠光体、铁素体和奥氏体型不锈耐热钢。为了提高火力发电机组的热效率、降低燃耗，世界各国均以发展大容量、高参数（高温、高压）火电机组（1000MW以上）为主。蒸汽压力提高到31.5～34.3MPa，过热蒸汽温度达595～650℃，向超高压临界压力发展，这样对高压锅炉管提出了更高的要求。为此开发了新的钢种，以满足高参数电站锅炉的需用。
