style="text-indent:25px">與不銹鋼封頭產(chǎn)品比較類似的產(chǎn)品有盲板、管帽、堵頭等。不銹鋼封頭的常見(jiàn)規(guī)格為Ф32毫米到6000毫米；厚度為1毫米到60毫米。該產(chǎn)品還有很多其他的稱呼，比如不銹鋼無(wú)直邊封頭、桶體旋邊、橢圓封頭、碟形封頭、淺形封頭、各種大小頭旋邊、不銹鋼大小頭旋邊、平底、半球形旋邊、球形封頭等。那么，不銹鋼封頭究竟起到了什么樣的作用呢？事實(shí)上，在石油、化工等工業(yè)領(lǐng)域中，封頭是屬于壓力容器設(shè)備中不可缺少的重要部件。封頭其實(shí)是壓力容器上的端蓋，是壓力容器的一個(gè)主要承壓部件，也具有良好的密封作用。封頭的碟板裝置配套法蘭主張采用碟閥**法蘭。安徽316L封頭廠制造</p><p style="text-indent:25px">封頭為了防止對(duì)外泄漏，往往將填料壓得很緊。安徽316L封頭廠制造</p><p style="text-indent:25px">封頭應(yīng)對(duì)環(huán)向應(yīng)力在時(shí)，封頭過(guò)渡區(qū)將開(kāi)始出現(xiàn)壓應(yīng)力，若長(zhǎng)短軸比值繼續(xù)增大，封頭過(guò)渡區(qū)邊緣的壓應(yīng)力值將迅速增大，即封頭越淺，封頭邊緣的壓應(yīng)力值越高，所以將封頭長(zhǎng)短軸比值限制在2.6以內(nèi)較為合理。封頭厚度除應(yīng)滿足強(qiáng)度要求外，對(duì)大直徑薄壁的橢圓封頭，還要提放由于封頭過(guò)渡區(qū)的壓應(yīng)力，產(chǎn)生內(nèi)壓下的彈性失穩(wěn)，為此封頭頭厚度還應(yīng)滿足剛度要求。封頭是指用以封閉容器端部使其內(nèi)外介質(zhì)隔離的元件，又稱端蓋。圓筒形容器的封頭一般都是迥轉(zhuǎn)殼體。安徽316L封頭廠制造</p><p
