style="text-indent:25px">球形封頭的性能與特點(diǎn)分析：1、從受力情況看：球形封頭的兩向應(yīng)力相等，而且在相同的P和D條件下，球形封頭上的應(yīng)力*為筒體上的周向應(yīng)力的一半；橢圓形封頭經(jīng)線(xiàn)曲率變化平滑連續(xù)，故應(yīng)力分布比較均勻，對(duì)于標(biāo)準(zhǔn)橢圓形封頭ab2，在相同的P和D條件下，封頭較大的薄膜應(yīng)力數(shù)值上與圓筒中的周向應(yīng)力相等。故橢圓形封頭的受力狀況*次于半球形封頭，而比其它封頭好；2、從制造難易程度看：橢圓形封頭的深度比半球形封頭淺的多，較易制造；3、從制造所使用的材料多少來(lái)看：從理論上講，在一些條件均相同之下，標(biāo)準(zhǔn)橢圓形封頭壁厚大約比半球形封頭厚一倍，而與圓筒的壁厚相近。故球形封頭比橢圓形封頭更節(jié)約材料。4、從結(jié)構(gòu)上看：球形封頭為半個(gè)球殼。5、球形封頭因具有受力均勻、應(yīng)力較小的等優(yōu)點(diǎn)被普遍用于壓力較高、直徑較大的高壓容器和特殊需要的場(chǎng)合；橢圓形封頭經(jīng)線(xiàn)曲率變化平滑連續(xù)，易于沖壓成型，是目前應(yīng)用較多的封頭。</p><p style="text-indent:25px">我們大多數(shù)使用不銹鋼封頭，都是要求能夠比較長(zhǎng)時(shí)間的將建筑物的外貌能夠長(zhǎng)期進(jìn)行保持。不銹鋼封頭在進(jìn)行選擇不銹鋼的一個(gè)類(lèi)型的時(shí)候，一般大部分都是進(jìn)行思考所要求的一個(gè)審美標(biāo)準(zhǔn)，還有所在環(huán)境下的一個(gè)大氣的腐蝕性，以及需要使用的一個(gè)清理制度。如果我們是在一個(gè)比較干燥的室內(nèi)環(huán)境下面使用的話(huà)，那么使用430不銹鋼就可以了。但是如果是在鄉(xiāng)村以及城市的戶(hù)外，想要能夠保持其的一個(gè)外觀，那么就需要我們進(jìn)行經(jīng)常的清洗。要是在污染比較嚴(yán)重的工業(yè)區(qū)以及沿海地區(qū)的話(huà)，那么表面就會(huì)比較的在哪個(gè)，有的甚至是會(huì)出現(xiàn)生銹的情況。我們要是想要在戶(hù)外的環(huán)境下有一個(gè)好的審美效果，較好是選用含鎳不銹鋼。所以一般304不銹鋼制作的封頭，都會(huì)運(yùn)用于屋頂、側(cè)墻等一些其它的建筑用途，如果是侵蝕性比較嚴(yán)重的工業(yè)或者是海洋大氣里面，我們較好使用的為316不銹鋼。半球封頭是由一塊園形坯料，經(jīng)圧制而成其為半球形。</p><div
