style="text-indent:25px">球形封頭類產(chǎn)品的主要特點是徑向應(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。</p><p

style="text-indent:25px">在使用狀態(tài)下的壓力容器產(chǎn)生的主要應(yīng)力有：容器內(nèi)的壓力產(chǎn)生的應(yīng)力；焊接殘余應(yīng)力；由于不銹鋼封頭成形加工產(chǎn)生的殘余應(yīng)力。三個應(yīng)力的疊加，使不銹鋼封頭與筒體連接的環(huán)焊縫部分存在的拉伸應(yīng)力大。所以不銹鋼封頭與筒體連接的環(huán)焊縫兩側(cè)易產(chǎn)生應(yīng)力腐蝕。而表面的劃痕，焊渣，飛濺，表面清洗不，采用含氯離子的保溫材料等因表面防護(hù)不當(dāng)會引起表面點腐蝕并誘發(fā)應(yīng)力腐蝕。封頭是壓力容器的重要受力部件，對于承接容器部件有比較重要的作用，封頭無論在選材還是制造技術(shù)是比較嚴(yán)格的，只有達(dá)到的要求才能運(yùn)用到工作的實踐中。1、封頭使用條件比較苛刻。封頭不但承受著大小不同的壓力載荷(在一般情況下還是脈動載荷)和其他載荷，而且有的還是在高溫或深冷的條件下運(yùn)行，工作介質(zhì)又往往具有腐蝕性，工況環(huán)境比較惡劣。2、封頭容易超負(fù)荷。容器內(nèi)的壓力常常會因操作失誤或發(fā)生異常反應(yīng)而迅速升高，而且往往在尚未發(fā)現(xiàn)的情況下，容器即已破裂。破裂后容器的可能力就會降低，從而影響工作的進(jìn)程，耽誤工作的進(jìn)度。因此制造的封頭，提高封頭的承載力。上海油罐封頭企業(yè)</p><p
