低中壓鍋爐管GB3087-2008、20G高壓鍋爐管GB5310-2008是用于制造各種結構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)碳素結構鋼熱軋和冷拔（軋）無縫鋼管。結構用無縫鋼管（GB/T8162-2008）是用于一般結構和機械結構的無縫鋼管。 </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構件、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，可以大大減輕結構重量，節(jié)約鋼材. </p> <p> 檢驗及鋼號

試樣在拉伸過程中，在拉斷時所承受的力(Fb)，出以試樣原橫截面積(So)所得的應力(σ)，稱為抗拉強度(σb)，單位為N/mm(MPa)。它表示金屬材料在拉力作用下抵抗破壞的能力。計算公式為: </p> <p> 式中:Fb--試樣拉斷時所承受的力，N(牛頓); So--試樣原始橫截面積，mm。 </p> <p> 屈服點 </p> <p> 具有屈服現(xiàn)象的金屬材料，試樣在拉伸過程中力不增加(保持恒定)仍能繼續(xù)伸長時的應力，稱屈服點。若力發(fā)生下降時，則應區(qū)分上、下屈服點。屈服點的單位為N/mm(MPa)。 </p> <p> 上屈服點(σsu):試樣發(fā)生屈服而力首次下降前的應力; 下屈服點(σsl):當不計初始瞬時效應時，屈服階段中的小應力。 </p> <p> 屈服點的計算公式為: </p> <p> 式中:Fs--試樣拉伸過程中屈服力(恒定)，N(牛頓)So--試樣原始橫截面積，mm。 </p> <p> 斷后伸長率<br /> 在拉伸試驗中，試樣拉斷后其標距所增加的長度與原標距長度的百分比，稱為伸長率。以σ表示，單位為%。計算公式為: </p> <p> 式中:L1--試樣拉斷后的標距長度，mm; L0--試樣原始標距長度，mm。 </p> <p> 斷面收縮率<br /> 在拉伸試驗中，試樣拉斷后其縮徑處橫截面積的縮減量與原始橫截面積的百分比，稱為斷面收縮率。以ψ表示，單位為%。計算公式如下: </p> <p> 式中:S0--試樣原始橫截面積，mm; S1--試樣拉斷后縮徑處的少橫截面積，mm。 </p> <p> 硬度指標 </p> <p> 金屬材料抵抗硬的物體壓陷表面的能力，稱為硬度。根據(jù)試驗方法和適用范圍不同，硬度又可分為布氏硬度、洛氏硬度、維氏硬度、肖氏硬度、顯微硬度和高溫硬度等。對于管材一般常用的有布氏、洛氏、維氏硬度三種。 </p> <p> A、布氏硬度(HB) </p> <p> 用一定直徑的鋼球或硬質(zhì)合金球，以規(guī)定的試驗力(F)壓入式樣表面，經(jīng)規(guī)定保持時間后卸除試驗力，測量試樣表面的壓痕直徑(L)。布氏硬度值是以試驗力除以壓痕球形表面積所得的商。以HBS(鋼球)表示，單位為N/mm(MPa)。 </p></div><p><img

GB3087標準鍋爐管是用鋼錠或?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。 <br /> 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。
