style="text-indent:25px">越大型號的封頭使用過程中會相對的問題較多，我們來看看封頭的使用要注意一些什么?1、封頭的形狀：根據(jù)設(shè)備的需求與合理，選擇合適的封頭種類：如橢圓形、蝶形、錐形、球形等；2、封頭的尺寸：是指的內(nèi)徑還是外徑。如377、426是以外徑為準；350、400、450是以內(nèi)徑為準；3、封頭的高度：一般封頭的高度我們都是按照國家標準來生產(chǎn)，但是也有客戶的產(chǎn)品設(shè)計不一樣，需要的封頭高度不同，所以有特殊要求定貨雙方要協(xié)商一致；4、封頭的材質(zhì)：一般使用較多的是304不銹鋼和碳鋼兩種，但是也有特殊用途的，如耐高溫必須用310S材質(zhì)、耐酸性一定要使用316L材質(zhì)等；5、封頭的周長：封頭是用模具沖壓成形，鋼板在沖壓過種中會有一些應(yīng)力存在，而且沖壓拉伸過程中會有相對變形，那么封頭的直徑要如何判斷準確與否，就看周長多少，是否標準；6、封頭與筒體焊接：封頭與筒體對焊的時候，一定是先將封頭與筒體用幾個點平均固定，再均勻的進行焊接處理。</p><p style="text-indent:25px">封頭的種類比較多，包括凸形封頭、錐殼、變徑段、平蓋及緊縮口的設(shè)計，凸形封頭包括：半球形封頭、橢圓形封頭、碟形封頭和球冠形封頭。從受力角度看凸形封頭中從半球形封頭逐漸不好，但從制造難度上看，逐漸好制造。封頭因不同的型號制造方式也不同。如小封頭，在制造時整體成型，而大、中型封頭需要先拼接后成型。這種制造方法用的多，標準中的要求主要針對它而言。對于大型封頭，由于運輸和打開等因素，需要將其先分成多個部分，然后組裝并焊接在一起。球形封頭適用與是氣體、液體和蒸汽等容器中。</p><div

style="text-indent:25px">在封頭種類里面，有這樣一類封頭，它的任意尺寸都可以定做，無論是否有模具，都能生產(chǎn)出來，這種封頭，就是我們常說的無直邊封頭，也叫球冠形封頭，還有一種叫法是太陽盤封頭。無直邊封頭：其形狀就是一個圓弧底，沒有直邊，像一個鍋底一樣。這種封頭結(jié)構(gòu)非常簡單，因為任意尺寸都可以定做，局限性小，所以在比較多非標設(shè)備中也常常受到客戶青睞。但是在定做這種封頭時，高度以及弧度非常重要，因為沒有標準的模具，所以在成型之后，會有較大的誤差。正所謂，有利就有弊，雖然任何尺寸都可以做，但是當無直邊封頭焊接時，因為沒有直邊，所以操作起來沒有其它形狀的封頭方便，因此，在對焊之時一定要非常注意操作，較好是選擇讓技術(shù)熟練的焊接工人進行處理。封頭的衛(wèi)生性能是否符合國家標準規(guī)定。蘇州水處理設(shè)備封頭廠家聯(lián)系方式</p><p
