class="khcont">無縫化鋼管依據(jù)成型方式不同分為無縫鋼管、焊接鋼管和熱擴管等幾類。無縫鋼管執(zhí)行標(biāo)準為《低中壓輸送流體用無縫鋼管》(GB/T8163-1999)，是指利用柱狀鋼坯加熱，模具穿孔方式生產(chǎn)的熱軋鋼管和利用冷拔機組將原管拉伸方式生產(chǎn)的冷拔鋼管。該類鋼管特點為管徑大、直度好、壁厚大、產(chǎn)量低、耗能大、成本高、長度10米左右且非定尺，另外一個重要特征是所有鋼管均有偏壁現(xiàn)象，即壁厚不均勻,偏差較大。焊接鋼管目前根據(jù)焊縫形式不同分為直縫焊接鋼管、螺旋焊接鋼管兩種，直縫焊接鋼管就焊接工藝不同又分為直縫電阻焊鋼管（ERW）和直縫埋弧焊鋼管（LSAW），執(zhí)行標(biāo)準為《低壓流體輸送用焊接鋼管》(GB/T3091-2001)，焊接鋼管均是利用軋輥等模具將帶鋼延圓形漸開線逐步卷為圓形，再通過埋弧、電阻等不同焊接方式焊接成型生產(chǎn)的鋼管。該成型方式的特點是產(chǎn)品產(chǎn)量高、成本低、耗能小、長度可以達16米且可以定尺、直徑及壁厚可良好控制，缺點主要是目前國內(nèi)鋼管生產(chǎn)設(shè)備技術(shù)落后，導(dǎo)致焊縫部分強度不足，壁厚一般國內(nèi)無法做厚。</div><p><img

要么就會現(xiàn)，泄露問題。要么就是現(xiàn)了，管道爆裂情況。后來經(jīng)過朋友介紹，李先生知道了，一種新鋼管種類，這就是無縫鋼管。這種管道采了，熱軋冷拔制作工藝。這讓鋼管面對，環(huán)境能力分強。了無縫鋼管之后，這些問題都不存在了。<br /> 這使得我們，平時所看到鋼管，多數(shù)都處于生銹狀態(tài)?？墒窃诮鼛啄曛?，這種情況越來越少見了，那就是因為，無縫鋼管替了普通鋼管。之所以運輸行業(yè)，會選擇無縫鋼管，這有著很多方面因。首先個因，那就是無縫鋼管，對于自身規(guī)格，有著分嚴格要求。</div><p><img

class="khcont4">以ψ表示，單位為%。計算公式如下：式中：S0--試樣原始橫截面積，mm2；S1--試樣拉斷后縮徑處的少橫截面積，mm2。硬度指標(biāo)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。A、布氏硬度（HB）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/mm2(MPa)。其計算公式為：式中：F--壓入金屬試樣表面的試驗力，N；D--試驗用鋼球直徑，mm；d--壓痕平均直徑，mm。測定布氏硬度較準確可靠，但一般HBS只適用于450N/mm2（MPa）以下的金屬材料，對于較硬的鋼或較薄的板材不適用。在鋼管標(biāo)準中，布氏硬度用途廣，往往以壓痕直徑d來表示該材料的硬度，既直觀，又方便。

class="khcont">無縫管業(yè)內(nèi)對焊管的認知，不盡相同。相對來說，東南沿海及長江中下游的無縫管企業(yè)較早接受，例如寶鋼前幾年就開始策劃上高頻直縫焊管ERW610mm機組、5m寬厚軋機和UOE大口徑直縫埋弧焊管生產(chǎn)線；武鋼集團擬開發(fā)2250mm寬帶熱連軋機及ERW610mm機組；大冶無縫鋼管廠在研討發(fā)展方向時決定避開焊管的優(yōu)勢，不上大口徑無縫管生產(chǎn)線，生產(chǎn)發(fā)揮無縫管厚壁優(yōu)勢的產(chǎn)品；天津無縫鋼管有限公司也在研究發(fā)展焊管產(chǎn)品、熱帶生產(chǎn)線的可行性。在無縫管企業(yè)內(nèi)部，營銷部門比技術(shù)部門對焊管產(chǎn)品的認知要早；在技術(shù)部門內(nèi)，一般技術(shù)人員與資深技術(shù)專家的感受也不盡相同。在行業(yè)外，石油系統(tǒng)比冶金系統(tǒng)認知焊管要早。技術(shù)本身在發(fā)展，但有的快、有的慢。板、帶、棒、線材發(fā)展連鑄連軋技術(shù)快，而無縫管材就慢，因而成本居高不下。國外焊管品種隨著焊接技術(shù)的進步快速發(fā)展，從水煤氣管發(fā)展到套管、鍋爐管。我國在1987-1992年間，大慶、勝利和塔里木油田僅從日本新日鐵就購買了規(guī)格為￠137–337mm，的油井用焊管16萬噸。
