冶金工程介紹高壓鍋爐管是鍋爐管的一種，屬于無(wú)縫鋼管類別。制造方法與無(wú)縫管高壓鍋爐管相同，但對(duì)制造鋼管所用的鋼種有嚴(yán)格的要求。高壓鍋爐管使用時(shí)經(jīng)常處于高溫和高壓條件。高壓鍋爐管主要用來(lái)制造高壓和超高壓鍋爐的過(guò)熱器管、再熱器管、導(dǎo)氣管、主蒸汽管等。鍋爐管由于長(zhǎng)期在高溫和高壓條件下工作，材料將發(fā)生蠕變，塑性和韌性下降，原始組織改變，產(chǎn)生腐蝕等。作為鍋爐用的鋼管應(yīng)具備：（1）足夠的持久強(qiáng)度；（2）足夠的塑性變形能力； （3） 最小的時(shí)效傾向和熱脆性；（4）高的抗氧化、耐煤灰、耐天然氣高溫下腐蝕、蒸汽和應(yīng)力腐蝕性能；（5）良好的組織穩(wěn)定性以及良好的工藝性能。高壓鍋爐管的鋼種有碳鋼以及珠光體、鐵素體和奧氏體型不銹耐熱鋼。為了提高火力發(fā)電機(jī)組的熱效率、降低燃耗，世界各國(guó)均以發(fā)展大容量、高參數(shù)（高溫、高壓）火電機(jī)組（1000MW以上）為主。蒸汽壓力提高到31.5～34.3MPa，過(guò)熱蒸汽溫度達(dá)595～650℃，向超高壓臨界壓力發(fā)展，這樣對(duì)高壓鍋爐管提出了更高的要求。為此開(kāi)發(fā)了新的鋼種，以滿足高參數(shù)電站鍋爐的需用。
