1、容器封頭的各個部分的尺度比例要合適，一般淺拉伸件比較好加工，如果遇到有凸緣和深度較大的容器封頭時，我們是需要較多的拉伸次數(shù)的，這也增加了生產(chǎn)成本，2、在容器封頭限制中，其形狀應(yīng)盡量簡單，并且對稱；主要是因?yàn)?，軸對此的拉伸件，在圓周方向上是有均勻變形的，江蘇碟形封頭制造廠，并且簡單容器封頭也是好加工的；3、在拉伸容器封頭中，其圓角半徑也要適宜，拉伸件的底與壁，江蘇碟形封頭制造廠、凸緣與壁等都要滿足一定的要求，江蘇碟形封頭制造廠，并且恰當(dāng)?shù)脑龃髨A角半徑，還能夠有利于成形；4、要確保容器封頭的厚度均勻，其上面孔的位置也要合理。封頭用于閥門兩端壓差大的工作場景。江蘇碟形封頭制造廠</p><div

style="text-indent:25px">不銹鋼封頭是石油化工、原子能到食品制藥諸多行業(yè)壓力容器設(shè)備中不可缺少的重要部件。封頭是壓力容器上的端蓋，是壓力容器的一個主要承壓部件。所起的作用是密封作用。一是做成了罐形壓力容器的上下底，二是管道到頭了，不準(zhǔn)備再向前延伸了，那就用一個封頭在把管子用焊接的形式密封住。和封頭的作用差不多的的產(chǎn)品有盲板和管帽，不過那兩種產(chǎn)品是可以拆卸的。而封頭焊好了之后是不可以再拆卸的。與之配套的管件有壓力容器、管道、法蘭盤、彎頭、三通、四通等產(chǎn)品。不銹鋼封頭的品質(zhì)直接關(guān)系到壓力容器的長期安全可靠運(yùn)行。我國現(xiàn)有的封頭標(biāo)準(zhǔn)，是按結(jié)構(gòu)型式（橢圓形、碟形、錐形）、成形方式（沖壓、旋壓）的不同，而分別制訂的，這不僅造成不同標(biāo)準(zhǔn)封頭質(zhì)量要求不完全一致的不合理現(xiàn)象，同時也給標(biāo)準(zhǔn)封頭的選用、標(biāo)準(zhǔn)的修訂帶來某些困難。橢圓形的封頭經(jīng)線曲率變化平滑連續(xù)，故應(yīng)力分布比較均勻。</p><div
