石油鉆桿接頭是在石油勘探開采鉆井時，用于連接上、下鉆桿的重要部件，由于其長期工作在含砂多，且有一定腐蝕性介質(zhì)的井下，所以要求其具有優(yōu)良的耐磨、耐蝕性能。為了改善其耐磨、耐蝕性能，提高其使用壽命，目前國內(nèi)許多企業(yè)采用粉末等離子噴焊的方法在其接頭部位噴焊一層耐磨帶。實驗結果表明，噴焊層主要由：γ-Fe、Cr23C6、(Cr,Fe)7C3以及NiB、萊氏體等化合物相組成。焊層冶金結合較好，**致密，稀釋率低，無裂紋、夾雜等缺點。同時擁有較高的硬度（55～68HRC）和耐磨性，具有較大的應用價值。2、鉆桿是石油天然氣行業(yè)進行油氣資源勘探，開發(fā)過程中不可或缺的工具，是組成鉆柱的主要部件。在石油勘探開采鉆井時，鉆桿接頭用于連接上、下鉆桿，是石油鉆桿的薄弱環(huán)節(jié)，80%以上的鉆桿***出現(xiàn)在這個部位。因此提高鉆桿接頭的質(zhì)量，是降低***的關鍵。3、據(jù)了解，目前國內(nèi)大部分油田的鉆井深度都達到了幾百米，有的甚至更深，達到幾千米，而且?guī)r層復雜堅硬，鉆桿在工作過程中，其外壁尤其是接頭部位要與井壁或套管接觸，所以承受著劇烈的磨損。由于鉆桿接頭周圍接觸面存在很多硬質(zhì)點，所以磨損主要以磨粒磨損為主，特別是下部目的層段使用屏蔽暫堵鉆井液時。</p><p style="text-indent:25px"> 首先，恢復工件尺寸堆焊，由于磨損或加工失誤造成工件尺寸不足，是廠礦企業(yè)經(jīng)常遇到的問題。用堆焊方法修復上述工件是一種很常用的工藝方法，修復后的工件不僅能正常使用，很多情況下還能超過原工件的使用壽命，因為將新工藝新材料用于堆焊修復，可以大幅度提高原有零部件的性能。其次，耐磨損、耐熱、耐腐蝕堆焊。磨損和腐蝕是造成金屬材料失效的主要因素，為了提高金屬工件表面耐磨性和耐蝕性，以滿足高溫等的工作條件要求，延長工件使用壽命，可以在工件表面堆焊一層或幾層耐磨或耐蝕耐熱層。就是將工件的基體與表面堆焊層選用具有不同性能的材料，制造出雙金屬工件。由于只是工件表面層具有合乎要求的耐磨、耐蝕等方面的特殊性能，所以充分發(fā)揮了材料的作用與工作潛力，而且節(jié)約了大量的貴重金屬。上海鉆桿堆焊都應用在什么地方？</p><div

style="text-indent:25px">為什么等離子熔覆（堆焊）不易產(chǎn)生裂紋·氣孔等缺點：主要原因有三。一是等離子做熱源進行熔覆（堆焊）與埋弧焊氣保焊等熱量更加集中，離子弧穩(wěn)定性更好，沒有電極熔耗，輸出熱量均勻，便于控制，這樣使得熔鑄區(qū)熱量分布均勻，材料熔合充分均勻，排氣浮渣都充分，收縮應力分布均勻。二是由于等離子設備控制精度高，對熔鑄區(qū)和過渡區(qū)的控制方便，且均勻度好，應力分配更容易控制合理。三是用氬氣保護不需要各種添加劑，也不存在排氫，氧化等問題，所以等離子熔覆（堆焊）更適合大面積，大厚度，高質(zhì)量的硬面熔鑄（如高錳·高鉻陶瓷材料等）適合于制造耐磨板、閥門、軋輥等。上海鉆桿堆焊的技術難點有哪些。重慶耐磨帶鉆桿堆焊噴焊機</p><p style="text-indent:25px">上海鉆桿堆焊未來的發(fā)展方向是什么？重慶鉆桿堆焊設備廠家</p><p> 采用等離子弧堆焊技術獲得的復合堆焊層質(zhì)量穩(wěn)定可靠.復合材料等離子弧堆焊技術的***進展可使堆焊層達到無氣孔，裂紋及碳化物燒損，熔解等缺點.碳化物顆粒在堆焊層中分布均勻.耐磨材料堆焊層耐磨性高，在磨損嚴重的工況條件下，復合堆焊層的耐磨性表現(xiàn)尤為突出，可較通常的鐵，鈷，鎳基舍金表面保護層提高耐磨使用壽命幾倍甚至十幾倍.具有較高的結合強度.由于堆焊層與被保護工件表面是冶金結合，因此可以滿足很高的強度要求.同熱噴涂獲得的復合耐磨保護層比較，堆焊層結合強度是熱噴涂層結合強度的3—8倍.復合堆焊層能滿足一定的抗沖擊要求.例如，水泥生產(chǎn)設備的石灰石破碎機錘頭，由于在磨損過程中所受的沖擊力較大，一般采用高錳鋼材料，使用壽命較低，在表面堆焊高碳高鉻合金后，易造成堆焊層破碎剝離，若采用復合耐磨堆焊層可避免這種情況發(fā)生，并且耐磨性明顯提高.可實現(xiàn)高教自動化生產(chǎn)，降低工人勞動強度。
