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。封頭其實是壓力容器上的端蓋，是壓力容器的一個主要承壓部件，也具有良好的密封作用。</p><p style="text-indent:25px">球形封頭類產(chǎn)品的主要特點(diǎn)是徑向應(yīng)力和環(huán)向應(yīng)力相等，而且球殼應(yīng)力只有筒體環(huán)向應(yīng)力的二分之一，應(yīng)力水平底，變形小。這樣就意味著在同樣壓力下這種產(chǎn)品的厚度要比殼體的厚度小一半。所以針對于一些中低壓力的容器，不建議選擇這種形狀的封頭產(chǎn)品。那么在設(shè)計一些橢圓形或者是蝶形產(chǎn)品的時候，為什么要設(shè)計直邊呢？這是因為其曲面底部與直邊段圓筒體相連接處會產(chǎn)生邊緣應(yīng)力。在這一交界面上，由于內(nèi)壓，圓筒徑向向外側(cè)膨脹，而封頭曲面底部徑向向內(nèi)收縮，從而產(chǎn)生一對剪力和一對彎矩。封頭施工、安裝要點(diǎn)：安裝位置、高度、進(jìn)出口方向有必要契合規(guī)劃要求。</p><div
