style="text-indent:25px">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(gè)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(gè)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(guò)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。封頭的品質(zhì)直接關(guān)系到壓力容器的長(zhǎng)期安全可靠運(yùn)行。根據(jù)幾何形狀的不同，可分為球形、橢圓形、碟形、球冠形、錐殼和平蓋等幾種，其中球形、橢圓形、碟形、球冠型封頭又統(tǒng)稱為凸形封頭。在焊接上分為對(duì)焊封頭，承插焊封頭。用于各種容器設(shè)備，如儲(chǔ)罐、換熱器、塔、反應(yīng)釜、鍋爐和分離設(shè)備等。旋壓法加工封頭的優(yōu)點(diǎn)：設(shè)備、工裝投資較模壓法少。無(wú)錫淺碟形封頭企業(yè)</p><p
