根據(jù)含碳量的高低，此類鋼又可分為： </p> <p> 低碳鋼--含碳量一般小于0.25%，如10、20鋼等； </p> <p> 中碳鋼--含碳量一般在0.25～0.60%之間，如35、45鋼等； </p> <p> 高碳鋼--含碳量一般大于0.60%。此類鋼一般不用于制造鋼管。 </p> <p> 實際上，他們之間的含碳量并沒有明顯的界限。 </p> <p> 此類鋼產(chǎn)量較大，用途較廣，一般多軋（鍛）制成圓、方、扁等型材、板材和無縫鋼管。主要用于制造一般結(jié)構(gòu)及機械結(jié)構(gòu)零、部件以及建筑結(jié)構(gòu)件和輸送流體用管道。根據(jù)使用要求，有時需熱處理（正火或調(diào)質(zhì)）后使用。20高壓鍋爐用無縫鋼管（GB5310-2008）是用于制造高壓及其以上壓力的水管鍋爐受熱面用的優(yōu)質(zhì)碳素鋼、合金鋼和不銹耐熱鋼無縫鋼管。 </p> <p> 高壓鍋爐管是鍋爐管的一種，屬于無縫鋼管類別。制造方法與無縫管相同，但對制造鋼管所用的鋼種有嚴格的要求。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?zé)煔夂退魵獾淖饔孟?，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(dǎo)氣管、主蒸汽管等。 </p> <p> 低中壓鍋爐管GB3087-2008、高壓鍋爐管GB5310-2008是用于制造各種結(jié)構(gòu)低高壓鍋爐過熱蒸汽管、沸水管及機車鍋爐用過熱蒸汽管、大煙管、小煙管和拱磚管用的優(yōu)質(zhì)碳素結(jié)構(gòu)鋼熱軋和冷拔（軋）無縫鋼管。結(jié)構(gòu)用無縫鋼管（GB/T8162-1999）是用于一般結(jié)構(gòu)和機械結(jié)構(gòu)的無縫鋼管。

title="鍋爐管-誠信為本"><br></p><div id="8qa0cg0" class="khcont"><p> 對成品鋼管顯微組織、晶粒度、脫碳層也有一定要求。 </p> <p> 高壓鍋爐管規(guī)格及外觀質(zhì)量：GB5310-95《高壓鍋爐用無縫鋼管》熱軋管的外徑22～530mm，壁厚20～70mm不等。冷拔(冷軋)管外徑10～108mm，壁厚2.0～13.0mm不等。 </p> <p> 15CrMoG高壓鍋爐管純化氫的原理是，在300—500℃下，把待純化的氫通入15CrMoG合金鋼管的一側(cè)時，氫被吸附在15CrMoG合金管壁上，由于鈀的4d電子層缺少兩個電子，它能與氫生成不穩(wěn)定的化學(xué)鍵（鈀與氫的這種反應(yīng)是可逆的），在鈀的作用下，氫被電離為質(zhì)子其半徑為1.5×1015m，而鈀的晶格常數(shù)為3.88×10－10m（20℃時），故可通過15CrMoG合金鋼管，在鈀的作用下質(zhì)子又與電子結(jié)合并重新形成氫分子，從15CrMoG合金管的另一側(cè)逸出。在15CrMoG合金管表面，未被離解的氣體是不能透過的，故可利用15CrMoG合金管獲得高純氫。 </p> <p> 表示方法 </p> <p> ① 鋼號開頭的兩位數(shù)字表示鋼的碳含量，以平均碳含量的萬分之幾表示，如40Cr。 </p> <p> ②鋼中主要合金元素，除個別微合金元素外，一般以百分之幾表示。當(dāng)平均合金含量<1.5%時，鋼號中一般只標出元素符號，而不標明含量，但在特殊情況下易致混淆者，在元素符號后亦可標以數(shù)字"1"，例如鋼號"12CrMoV"和"12Cr1MoV"，前者鉻含量為0.4-0.6%，后者為0.9-1.2%，其余成分全部相同。當(dāng)合金元素平均含量≥1.5%、≥2.5%、≥3.5%……時，在元素符號后面應(yīng)標明含量，可相應(yīng)表示為2、3、4……等。例如18Cr2Ni4WA。 </p> <p> ③鋼中的釩V、鈦Ti、鋁AL、硼B(yǎng)、稀土RE等合金元素，均屬微合金元素，雖然含量很低，仍應(yīng)在鋼號中標出。例如20MnVB鋼中。釩為0.07-0.12%，硼為0.001-0.005%。 </p> <p> ④高級優(yōu)質(zhì)鋼應(yīng)在鋼號后加"A"，以區(qū)別于一般優(yōu)質(zhì)鋼。 </p> <p> ⑤專門用途的合金結(jié)構(gòu)鋼，鋼號冠以（或后綴）代表該鋼種用途的符號。例如鉚螺專用的30CrMnSi鋼，鋼號表示為ML30CrMnSi。 </p> <p> 合金管與無縫管兩者既有關(guān)系又有區(qū)別，不能混為一談。 </p> <p> 合金管是鋼管按照生產(chǎn)用料（也就是材質(zhì)）來定義的，顧名思義就是合金做的管子；而無縫管是鋼管按照生產(chǎn)工藝（有縫無縫）來定義的，區(qū)別于無縫管的就是有縫管，包括直縫焊管和螺旋管。 </p></div><p><img src="http://2024aiimg.qy55.com//cjjhb_soft/142/1314/202402220522256055.jpg"
