style="text-indent:25px">封頭屬壓力容器中鍋爐部件的一種。通常是在壓力容器的兩端使用的。再有就是在管道的末端做封堵之用的一種焊接管件產(chǎn)品。有比較多種的形式。接下來(lái)我為您介紹一下山東封頭的標(biāo)準(zhǔn)。我國(guó)現(xiàn)有的封頭標(biāo)準(zhǔn)，是按結(jié)構(gòu)型式(橢圓形、碟形、錐形)、成形方式(沖壓、旋壓)的不同，而分別制訂的，這不*造成不同標(biāo)準(zhǔn)封頭質(zhì)量要求不完全一致的不合理現(xiàn)象，同時(shí)也給標(biāo)準(zhǔn)封頭的選用、標(biāo)準(zhǔn)的修訂帶來(lái)某些困難。1、以往的封頭標(biāo)。準(zhǔn)都是*與GB150《鋼制壓力容器》配套的，即只考慮了按規(guī)則設(shè)計(jì)的封頭的制造、檢驗(yàn)與驗(yàn)收要求，而我國(guó)早在1995年就完成GB150與JB4732了壓力容器基礎(chǔ)標(biāo)準(zhǔn)的雙軌制(與《鋼制壓力容器分析設(shè)計(jì)標(biāo)準(zhǔn)》)，缺少與分析設(shè)計(jì)相配套的封頭標(biāo)準(zhǔn)，不能不說(shuō)是我國(guó)壓力容器標(biāo)準(zhǔn)化工作的一大缺憾；2、GB150屬?gòu)?qiáng)制性標(biāo)準(zhǔn)，而根據(jù)GB150編制并與之配套的封頭標(biāo)準(zhǔn)卻是指導(dǎo)(推薦)性的，這顯然是不合理的，也難以保證封頭這一重要受壓元件的質(zhì)量。</p><p style="text-indent:25px">壓力容器用封頭有哪些？一般來(lái)說(shuō)壓力容器用封頭主要是按照封頭的形狀來(lái)進(jìn)行區(qū)分的，比較常見(jiàn)的有球形封頭、圓形封頭、橢圓形封頭、蝶形封頭。這些封頭根據(jù)需求不同，會(huì)進(jìn)行不同的選擇。這主要是因?yàn)閹缀涡螤詈统叽绲母淖?，就?huì)影響內(nèi)壓殼受壓力的變化，如果說(shuō)應(yīng)力不能在可控范圍內(nèi)的話(huà)，就會(huì)影響容器的整體承載能力，甚至有的部位就會(huì)成為設(shè)備的破壞源，所以多關(guān)注封頭的要求還是比較重要的。除了形狀之外，由于封頭要時(shí)時(shí)刻刻受到壓力，所以做工上的要求也比較高，尤其是在壓力容器封頭上的接管，它的結(jié)構(gòu)也是非常復(fù)雜的，開(kāi)孔的大小、位置以及受力的情況經(jīng)常會(huì)超出常規(guī)的設(shè)計(jì)范圍，所以要引入具體的分析設(shè)計(jì)，這樣才能保證平安的使用。球形封頭和筒體采用同樣薄厚還有益于降低鑄造缺陷、提升電焊焊接品質(zhì)，也相對(duì)減少器皿制造成本。</p><div

style="text-indent:25px">橢圓封頭劃傷主要是在搬運(yùn)過(guò)程中，操作不當(dāng)引起的。例如：吊鉤劃痕，叉車(chē)劃痕。解決方法：先在吊鉤和叉車(chē)與封頭接觸面墊保護(hù)膜，出現(xiàn)劃傷后，進(jìn)行打磨，嚴(yán)重的進(jìn)行補(bǔ)焊，劃傷面積超過(guò)百分之二十五要整體處理。如何增加橢圓封頭減薄率？成型封頭的厚度均勻可以避免應(yīng)力集中，增加封頭的使用周期，根據(jù)制造工藝確定加工裕量，以確保凸形封頭和熱卷筒節(jié)成形后的厚度不小于該部件的名義厚度減去鋼板負(fù)偏差。橢圓封頭大多數(shù)的橘皮現(xiàn)象出于板材本身有分層現(xiàn)象，然而肉眼是觀(guān)察不出來(lái)的，只能是在沖壓，壓鼓工序中，橘皮現(xiàn)象才能被發(fā)現(xiàn)。封頭屬壓力容器中鍋爐部件的一種，容器的一個(gè)部件，是以焊接方式連接筒體。無(wú)錫球型封頭廠(chǎng)制造</p><p
