style="text-indent:25px">封頭普遍應(yīng)用于制藥，化工，原子能，航天，機(jī)械它等方面。日常生活中經(jīng)常碰到，比如太陽能上兩側(cè)就是用的封頭，又比如，油罐的兩側(cè)也是使用的封頭等，可見不銹鋼封頭在我們生活，工作中是無處不在的。因此，維護(hù)好封頭才是硬道理。封頭的材質(zhì)分為碳鋼，合金，不銹鋼，首先為您介紹下不銹鋼封頭的維護(hù)，不銹鋼屬亞穩(wěn)定奧氏體不銹鋼，在450-850oC溫度范圍內(nèi)加熱時(shí)，鋼材中的碳和鉻結(jié)合析出碳化鉻。因?yàn)樘蓟t四周的含鉻量極度減少，形成貧鉻區(qū)，容易發(fā)生腐蝕。特別是焊接加工的焊道兩側(cè)區(qū)域和熱成形不銹鋼封頭容易發(fā)生這種現(xiàn)象。</p><p style="text-indent:25px">如何防止球形封頭變形？球形封頭中，根據(jù)壓機(jī)立柱間距和壓模尺寸及鋼板尺寸，選定頂圓需拼焊的板寬和拼焊塊數(shù)。盡可能采用壓鼓。直徑7.5m球形封頂圓取直徑6.2m，3塊板拼焊后壓鼓，然后車環(huán)縫坡口；直徑6.5m球形封頭頂圓取直徑5.36m，2塊板拼焊后壓鼓，然后車環(huán)縫坡口。直徑12m球形封頭頂圓取直徑lOm，直徑較大，由5塊板拼接，先分別壓形，然后切割研配向心、徑向縱縫坡口。為了防止自由變形，先制2個(gè)圓胎，檢測(cè)研配都可在此胎上進(jìn)行。球形封頭是以球殼的球冠部分所形成的封頭，有半球形封頭和無折邊球性封頭兩類。它在同樣容積下表面積較小，相同承壓條件下需要的厚度較薄，從節(jié)省材料和強(qiáng)度上看，是較合理的。另外，球形封頭具有鍛打精良，表面光滑，耐酸耐堿耐高溫，外形美觀，質(zhì)感性能強(qiáng)等特點(diǎn)。此類封頭為一塊深度比較淺的球面體(球冠)。其結(jié)構(gòu)見圖。它結(jié)構(gòu)簡單，深度淺，易加_百一制造，成本低。但它與筒體連接處存在著明顯的形狀突變，導(dǎo)致產(chǎn)生比較高的局部應(yīng)力，故受力狀況極差，所以這類封頭一般只能用于直徑比較小，壓力較低的容器。關(guān)于低溫壓力容器用橢圓封頭及需進(jìn)行疲勞剖析規(guī)劃的橢圓封頭，不得選用硬印作為資料的承認(rèn)符號(hào)和焊工標(biāo)志。</p><div

style="text-indent:25px">不銹鋼封頭的特點(diǎn)是不銹蝕、耐磨損、不結(jié)垢、減小振蕩和噪聲、防凍裂(超越-20℃的低溫下不銹鋼封頭發(fā)生凍裂，高溫的工作環(huán)境只需超越70℃發(fā)生分解，運(yùn)用溫度在-20℃到70℃)、防結(jié)露，熱丟失少、裝置簡單、運(yùn)用壽數(shù)長。由于在施工中選用融接技能，因此不銹鋼封頭也俗稱管帽，其無毒、質(zhì)輕、耐壓、耐腐蝕，正在成為一種耐腐蝕的管件。一般來說，這種原料不光適用于冷水封頭，也適用于熱水封頭，甚至純潔飲用水封頭。普遍運(yùn)用于施工中的不銹鋼封頭銜接方式是將鋼管或配管零件之接合端部份以砂紙磨掉外表層,如外表尚有油脂,應(yīng)用氯乙烯或**拭凈；將兩頭刺進(jìn)電焊套,兩頭必需插達(dá)電焊套之中心點(diǎn),刺進(jìn)時(shí)兩頭點(diǎn)不得有水.然后刺進(jìn)焊接控制器之二次線,開始焊接，進(jìn)程中不得移動(dòng)或碰觸及中途堵截電源或使二次線接合點(diǎn)松脫，焊接完結(jié)一小時(shí)后接合點(diǎn)徹底冷卻才能夠加壓於管內(nèi)及由外扳動(dòng)鋼管,以確保接合點(diǎn)不變形。封頭冷卻速度越快，含碳量和合金成分越高，不均勻塑性變形和殘余應(yīng)力越大。常州Q345R封頭廠制造</p><p
