石油鉆桿接頭是在石油勘探開(kāi)采鉆井時(shí)，用于連接上、下鉆桿的重要部件，由于其長(zhǎng)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(guó)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(shí)驗(yàn)結(jié)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(jié)合較好，**致密，稀釋率低，無(wú)裂紋、夾雜等缺點(diǎn)。同時(shí)擁有較高的硬度（55～68HRC）和耐磨性，具有較大的應(yīng)用價(jià)值。2、鉆桿是石油天然氣行業(yè)進(jìn)行油氣資源勘探，開(kāi)發(fā)過(guò)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(kāi)采鉆井時(shí)，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(gè)部位。因此提高鉆桿接頭的質(zhì)量，是降低***的關(guān)鍵。3、據(jù)了解，目前國(guó)內(nèi)大部分油田的鉆井深度都達(dá)到了幾百米，有的甚至更深，達(dá)到幾千米，而且?guī)r層復(fù)雜堅(jiān)硬，鉆桿在工作過(guò)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?chē)佑|面存在很多硬質(zhì)點(diǎn)，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(shí)。</p><p style="text-indent:25px">由于其優(yōu)異的技術(shù)特性，等離子堆焊技術(shù)在國(guó)內(nèi)外仍得到了大量應(yīng)用。在實(shí)際的工業(yè)生產(chǎn)中，等離子堆焊主要用于表面技術(shù)，以提高工件(閥門(mén)密封面、氣閥密封面、模具刃口、輸煤機(jī)中部槽板、槽幫、無(wú)縫鋼管頂頭、運(yùn)動(dòng)部件摩擦副等)的耐磨性能，以及石化工業(yè)設(shè)備的耐腐蝕性能，同時(shí)延長(zhǎng)使用壽命為主要目標(biāo)。采用各種堆焊材料提高零部件的性能，也是生產(chǎn)和研究的重點(diǎn)。但這些研究工作***于材料的表面改性上。如今高溫合金已應(yīng)用于航空航天、工業(yè)燃汽輪機(jī)及高速機(jī)車(chē)等方面，在長(zhǎng)期使用中就要求具有高的強(qiáng)度、較佳的抗氧化性能、耐蝕性能和良好的低周疲勞抗力，通常合金的成分及**對(duì)其性能有重大的影響，因此通過(guò)等離子堆焊技術(shù)在高溫合金的成形及加工方面的應(yīng)用，獲得均勻細(xì)小的**結(jié)構(gòu)成為改進(jìn)合金綜合性能的重要手段。隨著制造業(yè)的快速發(fā)展，為了滿(mǎn)足各種行業(yè)的需要，尤其是在快速制造領(lǐng)域，等離子沉積制造技術(shù)也得到人們的注意。有誰(shuí)知道上海鉆桿堆焊的產(chǎn)品功能嗎？</p><div

style="text-indent:25px"> 在堆焊過(guò)程中，焊炬除了按上述方法作階梯式的向前移動(dòng)外，還需沿著堆焊面作橫向擺動(dòng)，這樣可以提高堆焊層的均勻性和平整度。每堆焊一層可得到2～3mm厚的堆焊層，每層連續(xù)一次堆焊好。如果需要得到更厚的堆焊層，則須多層堆焊，層間須用砂輪或鋼絲刷進(jìn)行清理和平整，而后再堆焊下一層。根據(jù)需要可以用火焰重新熔化堆焊層（重熔），以減少堆焊層金屬的缺點(diǎn)，提高堆焊層質(zhì)量。（3）堆焊時(shí)，焊絲的熔化端、熔池必須始終處于“三倍乙炔過(guò)剩焰”的保護(hù)之中，使它們與空氣隔絕。不得將焊炬急速地從熔池表面移開(kāi)。堆焊搭接時(shí)，應(yīng)使接頭重疊15～20mm，收尾時(shí)須將焊炬繼續(xù)前移40～50mm，焊炬逐漸抬起，火焰逐漸離開(kāi)熔池，使熔池逐漸縮小。這樣，接頭處的冷卻速度緩慢，不至于產(chǎn)生接頭疏松、縮孔、火口裂紋等缺點(diǎn)?；鹧媸湛谠诃h(huán)縫的內(nèi)側(cè)為好，這樣可以減少堆焊接頭的收縮應(yīng)力。等離子粉末堆焊是以等離子弧作為熱源，應(yīng)用等離子弧產(chǎn)生的高溫將合金粉末與基體表面迅速加熱并一起熔化、混合、擴(kuò)散、凝固，等離子束離開(kāi)后自激冷卻，形成一層高性能的合金層，從而實(shí)現(xiàn)零件表面的強(qiáng)化與硬化的堆焊工藝。上海鉆桿堆焊設(shè)備涉及的內(nèi)容有哪些？重慶等離子堆焊鉆桿堆焊設(shè)備廠(chǎng)家</p><p style="text-indent:25px">鉆桿堆焊設(shè)備包含的內(nèi)容。重慶鉆桿堆焊</p><p> 為了保護(hù)鉆具和套管在鉆井過(guò)程中不至于過(guò)度磨損，采用堆焊方式或(其他方法)將堆焊材料沿鉆桿接頭圓周方向堆焊(或熔敷)寬約30～50mm、厚2～3mm的環(huán)形帶。此環(huán)形帶即稱(chēng)之為鉆桿接頭耐磨帶。目前在工程上使用的耐磨帶堆焊材料主要有鐵基合金粉末、碳化鎢顆粒和耐磨帶焊絲。 </p> <p> <br /> </p> <p> 一、鐵基合金粉末 </p> <p> <br /> </p> <p> 鐵基合金粉末是通過(guò)調(diào)整18-8型或Cr13型不銹鋼的Ni、Cr含量，并添加B、Si元素而成的。鐵基合金粉末的噴涂層硬度、致密性、結(jié)合強(qiáng)度等于鎳基合金粉末涂層大體相當(dāng)，因此在不少場(chǎng)合下可代替鎳基合金粉末，但涂層的韌性低于鎳基合金粉末涂層。鐵基合金粉末涂層具有良好的耐磨性。 </p> <p> <br /> </p> <p> 鉆桿接頭耐磨帶堆焊鐵基合金粉末采用的是等離子弧堆焊方法。等離子弧堆焊是利用轉(zhuǎn)移型等離子弧作為熱源，以鐵基合金粉末作填充金屬的一種堆焊工藝。其焊接溫度較高，容易造成局部組.織變大，且重復(fù)堆焊性變差，在應(yīng)用過(guò)程中，容易出現(xiàn)耐磨帶的開(kāi)裂和剝落。 </p> <p> <br />
