2.焊接鋼管因其焊接工藝不同而分為爐焊管、電焊（電阻焊）管和自動(dòng)電弧焊管，因其焊接形式的不同分為直縫焊管和螺旋焊管兩種，因其端部形狀又分為圓形焊管和異型（方、扁等）焊管。 </p> <p> 焊接鋼管是由卷成管形的鋼板以對(duì)縫或螺旋縫焊接而成，在制造方法上，又分為低壓流體輸送用焊接鋼管、螺旋縫電焊鋼管、直接卷焊鋼管、電焊管等。無(wú)縫鋼管可用于各種行業(yè)的液體氣壓管道和氣體管道等。焊接管道可用于輸水管道、煤氣管道、暖氣管道、電器管道等。泰安鋼塑管多少錢鍍鋅鋼管分為冷鍍鋅鋼管、熱鍍鋅鋼管，冷鍍鋅鋼管已被禁用，后者還被國(guó)家提倡暫時(shí)能使用。</p><div

焊管的熱處理工藝原理 </p> <p> 焊接鋼管在使用前，需要經(jīng)過(guò)各種工藝。焊接鋼管的熱處理是焊接鋼管加工中一個(gè)非常重要的環(huán)節(jié)。熱加工是將金屬材料置于一定的介質(zhì)中加熱、保溫、冷卻，通過(guò)改變材料表面或內(nèi)部的金相組織來(lái)控制其金屬性能的一種金屬熱加工技術(shù)。在加熱和冷卻過(guò)程中，由于表面與芯部冷卻速度和時(shí)間的不同，會(huì)形成溫差，導(dǎo)致體積膨脹和收縮不均勻，產(chǎn)生應(yīng)力，即熱應(yīng)力。 </p> <p> 在熱應(yīng)力作用下，表面溫度低于中心，收縮率也大于中心，使中心受拉。當(dāng)冷卻結(jié)束時(shí)，由于中心的較終冷卻體積收縮不能自由進(jìn)行，因此表面被壓縮，中心受到拉伸。也就是說(shuō)，在熱應(yīng)力的作用下，工件表層被壓縮，中心部分被拉扯。這種現(xiàn)象受冷卻速度、材料成分和熱處理工藝的影響。冷卻速度越高，碳含量和合金成分越高，在冷卻過(guò)程中熱應(yīng)力作用下的非均勻塑性變形越大，較終形成的殘余應(yīng)力越大。另一方面，在熱處理過(guò)程中，由于組織的變化，即從奧氏體轉(zhuǎn)變?yōu)轳R氏體，比容的增加會(huì)伴隨著工件體積的擴(kuò)大，而工件各部分的變形會(huì)導(dǎo)致體積增長(zhǎng)不一致，產(chǎn)生結(jié)構(gòu)應(yīng)力。組織應(yīng)力變化的較終結(jié)果是表面的拉應(yīng)力和中心的壓應(yīng)力，這與熱應(yīng)力正好相反。組織應(yīng)力的大小與馬氏體相變區(qū)的冷卻速度、形狀和工件的化學(xué)成分有關(guān)。熱鍍鋅鋼管在消防、電力和高速公路上有寬泛的應(yīng)用。</p><div
