20G高壓鍋爐管是，但對制造鋼管所用的鋼種有嚴格的要求。20G高壓鍋爐管使用時經(jīng)常處于高溫和高壓條件，管子在高溫煙氣和水蒸氣的作用下，會發(fā)生氧化和腐蝕。要求鋼管具有高的持久強度，高的抗氧化腐蝕性能，并有良好的組織穩(wěn)定性。高壓鍋爐管主要用來制造高壓和超高壓鍋爐的過熱器管、再熱器管、導氣管、主蒸汽管等。 </p> <p> 20G高壓鍋爐管采用的鍋爐受壓元件用鋼,一般在39公斤以下的鍋爐應用，為了在較高壓力下使用，往往都把受熱面管設計的很厚。為了減少熱阻和節(jié)省鋼材，保證較高或高壓鍋爐用鋼的性，同時也為了降低用鋼量，普遍采用的是16MnG。同時也有添加稀土、鎂等金屬和非金屬材料的特殊鋼材。這樣會提高鍋爐用鋼的性能，減少鋼材的耗量，同時也降低了熱阻。 </p></div><p><img

title="值得信賴的鍋爐管"><br></p><div id="64w4uwe" class="khcont"><p> 鍋爐管的用途分類 </p> <p> 用于低中壓鍋爐（工作壓力一般不大于5.88Mpa，工作溫度在450℃以下）的受熱面管子；用于高壓鍋爐（工作壓力一般在9.8Mpa以上，工作溫度在450℃～650℃之間）的受熱面管子、省煤器、過熱器、再熱器、石化工業(yè)用管等。 </p> <p> 按照組成材料分類可分為20G高壓鍋爐管、12Cr1MoVG高壓鍋爐管、鋼研102高壓鍋爐管、15CrMoG高壓鍋爐管、5310高壓鍋爐管、3087低中壓鍋爐管、40Cr高壓鍋爐管、1Cr5Mo高壓鍋爐管、42CrMo高壓鍋爐管。 </p> <p> <br /> 制造及用途 </p> <p> （1）生產(chǎn)制造方法： </p> <p> ①一般鍋爐管使用溫度在450℃以下，國產(chǎn)管主要用10號、20號碳結(jié)鋼熱軋管或冷拔管制造。 </p> <p> ②高壓鍋爐管使用時經(jīng)常處于高溫和高壓條件管子在高溫煙氣和水蒸氣的作用下，會發(fā)生氧化和腐蝕。要求鋼管具有高的持久強度，高的抗氧化腐蝕性能，并有良好的組織穩(wěn)定性。 </p> <p> （2）用途： </p> <p> ①一般鍋爐管主要用來制造水冷壁管、沸水管、過熱蒸汽管、機車鍋爐用的過熱蒸汽管，大、小煙管及拱磚管等。 </p> <p> ②高壓鍋爐管主要用來制造高壓和超高壓鍋爐的過熱器管、再熱器管、導氣管、主蒸汽管等。 </p> <p> 高壓鍋爐管的生產(chǎn)工藝隨鋼種的不同各有差異。以珠光體型鉻鉬釩鋼為例，鍋爐管的生產(chǎn)工藝特點是：（1）管坯應剝皮，剝皮量通常為5mm；（2）由于鋼質(zhì)較硬，管坯多用氧氣切割或鋸切；（3）由于鉻鉬釩鋼的導熱性比碳鋼低，加熱速度宜稍慢，加熱溫度為1120～1180℃，穿孔溫度為1100～1160℃；（4）這類鋼在1000～1100℃區(qū)間有良好的塑性和低的變形抗力，因而穿孔性能較好，變形參數(shù)可照中碳鋼或合金鋼（例如30CrMnSiA）選?。唬?）軋后鋼管要正火和回火，正火溫度為950～980℃，回火溫度為730～750℃，保溫時間為2～3h；（6）鋼管尺寸公差較嚴，以保證對口焊接；管子長度盡可能長，以利于減少焊口數(shù)量。
