衢江區(qū)前身為衢縣，始建于東漢初平三年（192年），已有1800多年歷史。2001年12月26日，經國務院批準撤銷衢縣，設立衢州市衢江區(qū)。蘊育了唐代高僧大徹禪師、北宋“鐵面御史”趙抃、南宋抗金名將徐徽言、狀元毛自知、明代“中華神針”楊繼洲等一批文化名人。境內有蔥口新石器洞穴遺址、廟山尖西周土墩墓群、初唐古寺明果寺、兩弓塘宋代青瓷遺址、金仙巖南宋摩崖石刻等歷史遺存；有天脊龍門風景區(qū)、藥王山景區(qū)、樓山后景區(qū)等景區(qū)。

class="khcont">20#和45#鋼的c、Si、Mn、P、S含量不同，45要高于20#鋼，你可以買本鋼材只是手冊看一下。20#鋼淬透性、淬硬性低、塑性、韌性、焊接性好，熱軋或正火后韌性更好，可制作不太重要的中、小型滲碳、碳氮共滲件、鍛壓件，如杠桿軸、變速箱變速叉、齒輪，重型機械拉桿、鉤環(huán)等。45#鋼是常用中碳調質鋼，綜合力學性能良好，淬透性低，水淬時易生裂紋。小型件宜采用調質處理，大型件宜采用正火處理，主要用于制造強度高的運動件，如透平機葉輪、壓縮機活塞。軸、齒輪、齒條、蝸桿等。它們通常適用無縫鋼管的材質，無縫鋼管又分為GB816GB8163這兩個常用的，但45#鋼只有GB8162才有，45#是機械加工的一種常用鋼管材質。普通冷拔無縫鋼管與精軋無縫鋼管的區(qū)別在于普通無縫鋼管主要特點是無焊接縫，可承受較大的壓力。產品可以是很粗糙的鑄態(tài)或冷撥件，適合用于機械加工，流體管道。精密鋼管是近幾年出現(xiàn)的產品，主要是內孔、外壁尺寸有嚴格的公差及粗糙度，外表光亮，但的一個缺點是不可以握彎，解決方法后退火但是退火后就不會發(fā)光了但是壁厚公差還可以保證。

class="khcont">直縫電阻焊鋼管與流體輸送用無縫鋼管相比具有相當?shù)募夹g優(yōu)勢，例如焊管壁厚較薄，尺寸精度較高，等等。檢查合格的鋼管耐力已達到2800psi(13MPa)，而管線管水壓試驗小合格壓力為1870psi(19MPa)，所試驗鋼管耐壓小合格壓力為930psi(4MPa)，這種用普通Q235材質制成的焊管已達到美國石油學會API51關于高材質X52級鋼種的小限壓力規(guī)定。關于直縫電阻焊鋼管與流體輸送用無縫鋼管的經濟性對比，由于生產成本低，直縫電阻焊鋼管的銷售價格比流體輸送用無縫鋼管低，實際采購情況表明，直縫電阻焊鋼管比流體輸送無縫鋼管每噸要低于1000元左右，并且隨著口徑的增大，差價可高達2000多元。這也是目前上大量發(fā)展大、中口徑直縫電阻焊管線輸送管、石油套管、油管的重要原因。無縫化鋼管無縫化鋼管結束語在《資本論》的序言中說:“工業(yè)較發(fā)達的向不發(fā)達所顯示的，只是后來者未來的景象”。西方工業(yè)發(fā)達鋼管生產結構成功轉型及其形成的由無縫管數(shù)量逐漸減少、焊管數(shù)量逐漸上升的替代路徑，這一景象在中國90年代已經初顯端倪，也開始印證了的預言。因此，我國焊管發(fā)展方向應當是:管型上重點發(fā)展直縫焊管，這個基本點不能動搖;在技術上強力推行無縫化技術;重點焊管企業(yè)向中、高層技術領域發(fā)展;螺旋焊管應當著力于進行技術改造，提高產品的檔次和質量，擴大自身的市場份額。

class="khcont5">焊接鋼管在一定領域內可以完全替代無縫鋼管。焊管的厚度公差高于無縫鋼管厚度公差，材料節(jié)省率高，成本低。這就是石業(yè)引進焊管產品的一個主要原因。中國的無縫管、軋管產品都受到西方先進焊管產品的挑戰(zhàn)，只有跳出單純數(shù)量擴張的圈子，狠抓技術進步，降低成本，產品向次發(fā)展才有前途。焊管發(fā)展方向的兩次重大研討會的觀點和影響國內有兩次涉及焊管發(fā)展方向的重大學術討論會：一次是1998年“大中直徑長輸管線用埋弧型直縫焊接鋼管研討會”，一次是2000年“天然氣管道輸送技術及制管技術高級研討會”。前一次研討會主張“發(fā)展直縫雙面埋弧焊管取代螺旋管”，后一次研討會提出“繼續(xù)堅持油氣輸送干線鋼管以國產螺旋焊管為主的技術路線”。這兩次研討會的結論截然相反，對制管業(yè)有不同影響。焊管發(fā)展方向問題的再認識但從前面敘述的焊管取代無縫管的論述來講，也只能夠是直縫焊管挑大梁而不是螺旋焊管，這就是西方為什么要大力發(fā)展直縫焊管的原因所在，也是咱們公司之所以選擇直縫焊管的原因所在?！拔鳉鈻|輸”工程的實踐已經從一個側面說明螺旋焊管可以用于輸送天然氣(一類地區(qū))；但螺旋焊管的生產工藝要適應成批、穩(wěn)定地生產大口徑（l000mm以上)、高鋼級(X70級以上)、厚厚(14mm以上)是頗為艱難的。</div><p></p><p><br/></p><div
