style="text-indent:25px">封頭是石油化工、原子能到食品制藥諸多行業(yè)壓力容器設(shè)備中不可缺少的重要部件。封頭是壓力容器上的端蓋，是壓力容器的一個(gè)主要承壓部件。所起的作用是密封作用。一是做成了罐形壓力容器的上下底，二是管道到頭了，不準(zhǔn)備再向前延伸了，那就用一個(gè)封頭在把管子用焊接的形式密封住。和封頭的作用差不多的的產(chǎn)品有盲板和管帽，不過那兩種產(chǎn)品是可以拆卸的。而封頭焊好了之后是不可以再拆卸的。與之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。封頭的品質(zhì)直接關(guān)系到壓力容器的長(zhǎng)期安全可靠運(yùn)行。根據(jù)幾何形狀的不同，可分為球形、橢圓形、碟形、球冠形、錐殼和平蓋等幾種，其中球形、橢圓形、碟形、球冠型封頭又統(tǒng)稱為凸形封頭。在焊接上分為對(duì)焊封頭，承插焊封頭。用于各種容器設(shè)備，如儲(chǔ)罐、換熱器、塔、反應(yīng)釜、鍋爐和分離設(shè)備等。鋁合金封頭加工封頭拋光通常會(huì)用專門的拋光機(jī)，這些拋光機(jī)的自動(dòng)化設(shè)計(jì)非常高。</p><div

style="text-indent:25px">封頭廠家分析造成球形封頭強(qiáng)度不夠的原因。球形封頭在我們的生活中比較常見，并且無論從工作的強(qiáng)度還是節(jié)省材料上來講，都是一種非常不錯(cuò)的選擇。而且球形封頭的設(shè)計(jì)合理，并采用無角焊縫的鏈接，受力更均勻，使用壽命更長(zhǎng)。經(jīng)過大量的研究發(fā)現(xiàn)，球形封頭無論是采用哪種形式，通常情況下它都是容器中較為薄弱的一個(gè)部位。并且球形封頭的強(qiáng)度一般還只有筒體強(qiáng)度的70%~80%左右。而造成球形封頭強(qiáng)度不夠的原因有比較多，如下面幾種：1.球形封頭與筒身連接處存在不連續(xù)應(yīng)力；2.纏繞張力不穩(wěn)定；3.纖維軌跡偏離理論位置；4.球形封頭曲面不準(zhǔn)確。封頭廠家除了要采取工藝措施改善球形封頭纖維的均勻分布狀態(tài)、降低纖維堆積高度、合理選擇纏繞線型、逐步擴(kuò)大纏繞包絡(luò)圈、環(huán)向加固容器的肩部等途徑提高封頭強(qiáng)度外，還必須對(duì)封頭補(bǔ)強(qiáng)，以使壓力容器整體同步失效。目前采用較多的一種補(bǔ)強(qiáng)方法是增加螺旋纏繞纖維用量。這種方法簡(jiǎn)便易行，不必對(duì)纏繞線型和封頭曲面進(jìn)行修正。引入螺旋纏繞纖維強(qiáng)度利用系數(shù)k，則實(shí)際螺旋纏繞纖維厚度應(yīng)當(dāng)增大。橢圓形的封頭的深度比半球形的封頭淺的多，較易制造。</p><div
