鋼材力學(xué)性能是保證鋼材較終使用性能（機(jī)械性能）的重要指標(biāo)，它取決于鋼的化學(xué)成分和熱處理制度。在鋼管標(biāo)準(zhǔn)中，根據(jù)不同的使用要求，規(guī)定了拉伸性能（抗拉強(qiáng)度、屈服強(qiáng)度或屈服點(diǎn)、伸長(zhǎng)率）以及硬度、韌性指標(biāo)，還有用戶(hù)要求的高、低溫性能等。 </p>

</p> <p> （1）將要對(duì)接的兩根鋼管放在同一平面的同一軸線(xiàn)上。 </p> <p> （2）保持兩管端部間隙在2-3mm之間。為保證焊接間隙距離，可在兩管間隙之間加墊。 </p> <p> （3）保證對(duì)接鋼管的坡口角度。 </p> <p> （4）鋼管焊接后30分鐘內(nèi)不得受外力移動(dòng)，否則對(duì)接焊縫會(huì)開(kāi)裂，影響鋼管的使用效果。 </p> <p> （5）對(duì)接焊縫如需進(jìn)行無(wú)損檢測(cè)（X射線(xiàn)底片或超聲波探傷），在條件允許的情況下，應(yīng)在焊接完成后24小時(shí)內(nèi)進(jìn)行。 </p> <p> 2、法蘭連接 </p>

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。鍍鋅鋼管鍍鋅可增加鋼管的抗腐蝕能力，延長(zhǎng)使用壽命。曹縣鋼塑管大概多少錢(qián)</p><p
