style="text-indent:25px">封頭等到冷卻結(jié)束之后，心部的冷卻體積也不能進(jìn)行自由的收縮，會讓材料和熱處理工藝受到影響。如果冷度速度快，那么相對的碳含量和合金量也越高，在進(jìn)行冷卻的時候存在不均勻塑形的幾率越高，會形成殘余應(yīng)力的可能性也越大。其實(shí)封頭的變大都表現(xiàn)在表層的受應(yīng)拉力、心部受壓應(yīng)力，這都和熱應(yīng)力是相反的，所以說應(yīng)力的大小和冷卻速度、形狀、材料的化學(xué)成分有關(guān)。封頭是安裝在一定體積的容器上的時候，要求其盡可能的起到密封的效果。封頭用于對調(diào)節(jié)質(zhì)量要求高的重要調(diào)節(jié)系統(tǒng)。</p><div

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。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。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。在焊接上分為對焊封頭，承插焊封頭。用于各種容器設(shè)備，如儲罐、換熱器、塔、反應(yīng)釜、鍋爐和分離設(shè)備等。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。蘇州封頭制作廠</p><p
