/> GB3087標準鍋爐管 </p> <p> GB3087鍋爐管是用鋼錠或?qū)嵭墓芘鹘?jīng)穿孔制成毛管，然后經(jīng)熱軋、冷軋或冷撥制成。GB3087鍋爐管在我國鋼管業(yè)中具有重要 </p> <p> GB3087鍋爐管的地位。據(jù)不完全統(tǒng)計，我國現(xiàn)有無縫管生產(chǎn)企業(yè)約240多家，無縫鋼管機組約250多套，年產(chǎn)能力約450多萬噸。從口徑看，<φ76的，占35%，<φ159-650的，占25%。從品種看，一般用途管190萬噸，占54%；石油管76萬噸，占5.7%；液壓支柱、精密管15萬噸，占4.3%；不銹管、軸承管、汽車管共5萬噸，占1.4%。 </p> <p> GB3087鍋爐管的原料是圓管坯，圓管胚要經(jīng)過切割機的切割加工成長度約為1米的坯料，并經(jīng)傳送帶送到熔爐內(nèi)加熱。鋼坯被送入熔爐內(nèi)加熱，溫度大約為1200℃。燃料為氫氣或乙炔。爐內(nèi)溫度控制是關(guān)鍵性的問題.圓管坯出爐后要經(jīng)過壓力穿孔機進行穿空。一般較常見的穿孔機是錐形輥穿孔機，這種穿孔機生產(chǎn)效率高，產(chǎn)品質(zhì)量好，穿孔擴徑量大，可穿多種鋼種。穿孔后，圓管坯就先后被三輥斜軋、連軋或擠壓。擠壓后要脫管定徑。定徑機通過錐形鉆頭高速旋轉(zhuǎn)入鋼胚打孔，形成鋼管。鋼管內(nèi)徑由定徑機鉆頭的外徑長度來確定。鋼管經(jīng)定徑后，進入冷卻塔中，通過噴水冷卻，鋼管經(jīng)冷卻后，就要被矯直。鋼管經(jīng)矯直后由傳送帶送至金屬探傷機（或水壓實驗）進行內(nèi)部探傷。若鋼管內(nèi)部有裂紋，氣泡等問題，將被探測出。鋼管質(zhì)檢后還要通過嚴格的手工挑選。鋼管質(zhì)檢后，用油漆噴上編號、規(guī)格、生產(chǎn)批號等。并由吊車吊入倉庫中。

低中壓鍋爐管GB3087-2008、20G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/T8162-2008）是用于一般結(jié)構(gòu)和機械結(jié)構(gòu)的無縫鋼管。 </p> <p> <br /> 異型無縫鋼管是除了圓管以外的其他截面形狀的無縫鋼管的總稱。按鋼管截面形狀尺寸的不同又可分為等壁厚異型無縫鋼管（代號為D）、不等壁厚異型無縫鋼管（代號為BD）、變直徑異型無縫鋼管（代號為BJ）。異型無縫鋼管廣泛用于各種結(jié)構(gòu)件、工具和機械零部件。和圓管相比，異型管一般都有較大的慣性矩和截面模數(shù)，有較大的抗彎抗扭能力，可以大大減輕結(jié)構(gòu)重量，節(jié)約鋼材.

(2)GB5310-2008《高壓鍋爐用無縫鋼管》規(guī)定。化學成分試驗方法按GB222-84及《鋼鐵及合金化學分析方法》、GB223《鋼鐵及合金化學分析方法》中的有關(guān)部分。 </p> <p> (3)進口鍋爐鋼管的化學成分檢驗按合同規(guī)定的有關(guān)標準進行。 </p> <p> 鍋爐管采用鋼號 </p> <p> (1)優(yōu)質(zhì)碳素結(jié)構(gòu)鋼鋼號有20G、20MnG、25MnG。 </p> <p> <br /> (2)合金結(jié)構(gòu)鋼鋼號15MoG、20MoG、12CrMoG、15CrMoG、12Cr2MoG、12CrMoVG、P11 12Cr3MoVSiTiB等。 </p> <p> (3)有銹耐熱鋼常用1Cr18Ni9、1Cr18Ni11Nb鍋爐管除保證化學成分和機械性能外，要逐根做水壓試驗，要作擴口、壓扁試驗。鋼管以熱處理狀態(tài)交貨。 </p></div><p><img src="http://2024aiimg.qy55.com//cjjhb_soft/142/1314/202402220522387356.jpg"
