style="text-indent:25px">影響封頭較小厚度的因素有哪些？1、剛度的影響：封頭在承受壓力的同時(shí)本身應(yīng)具備一定的剛度，以免發(fā)生變形破壞。因此，GB150規(guī)定，對(duì)碳素鋼、低合金鋼制容器不包括腐蝕裕量的較小厚度應(yīng)不小于3mm；對(duì)高合金鋼制容器不包括腐蝕裕量的較小厚度不小于2mm。2、壓力載荷的影響：封頭是承受一定壓力的受壓元件，首先必須滿(mǎn)足的條件是壓力載荷，無(wú)論承受內(nèi)壓或者外壓載荷的封頭都可通過(guò)GB150第3章有關(guān)計(jì)算公式得到封頭計(jì)算厚度，其中，計(jì)算厚度+腐蝕裕量=設(shè)計(jì)厚度，這個(gè)設(shè)計(jì)厚度是單從壓力載荷方面得到的封頭需要的較小厚度。3、內(nèi)壓失穩(wěn)的影響：內(nèi)壓作用下，標(biāo)準(zhǔn)橢圓封頭的應(yīng)力分布如圖1。由應(yīng)力分布圖可以看出，在封頭底邊處產(chǎn)生周向壓縮應(yīng)力，此處封頭容易發(fā)生周向失穩(wěn)。為防止橢圓封頭在內(nèi)壓作用下失穩(wěn)，GB150規(guī)定，對(duì)于Di/2hi≤2的橢圓形封頭的有效厚度應(yīng)不小于封頭內(nèi)直徑的0.15%，對(duì)于Di/2hi＞2的橢圓形封頭的有效厚度應(yīng)不小于封頭內(nèi)直徑的0.30%。上述雖然限制的是有效厚度，但其實(shí)也間接限制了封頭成形的較小厚度。江蘇雙氧水設(shè)備封頭生產(chǎn)廠家球形封頭的受力比橢圓形封頭和碟形封頭好。</p><div
