style="text-indent:25px">在使用封頭的時(shí)候，在焊接完成之后就無法拆卸了。其的品質(zhì)將會直接影響到壓力容器的長期安全可靠運(yùn)行。通常情況下，與該產(chǎn)品相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。那么你知道在GB150-1998標(biāo)準(zhǔn)中，對其厚度的定義是怎樣的嗎？首先是關(guān)于封頭產(chǎn)品的計(jì)算厚度，這一參數(shù)其實(shí)指的是按照各章公式計(jì)算得到的厚度。需要時(shí)，尚應(yīng)計(jì)入其他載荷所需厚度。其次是設(shè)計(jì)厚度，指的是計(jì)算厚度與腐蝕裕量之和。而關(guān)于其的名義厚度指的是設(shè)計(jì)厚度加上鋼材厚度負(fù)偏差后向上圓整至鋼材標(biāo)準(zhǔn)規(guī)格的厚度。</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(jì)一些橢圓形或者是蝶形產(chǎn)品的時(shí)候，為什么要設(shè)計(jì)直邊呢？這是因?yàn)槠淝娴撞颗c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。封頭能夠增大調(diào)節(jié)閥的輸出效率，減少滯后的情況發(fā)生。</p><div
