style="text-indent:25px">在高壓容器中，球形封頭與其他方式的封頭對比承受力是較好的，在同樣直徑和工作壓力下所需厚度少，節(jié)約原材料，因此在工作壓力較高的器皿中經(jīng)常應(yīng)用。與此同時(shí)，在所有形式的封頭與簡體連接中，球形厚度與筒體厚度相差較大，它們之間的連接結(jié)構(gòu)不*影響設(shè)備的制造而且也是容器能否正常運(yùn)行的重要因素之一，在GB150-1998中也將筒體與球形的對接環(huán)形焊縫定義為A類焊接接頭。在工程中，當(dāng)壁厚較小時(shí)，可采用封頭名義厚度與簡體名義厚度相同的方法，半球殼與圓筒的連接為切線連接，沒有橫推力，當(dāng)采用與筒體等厚的半球封頭時(shí)，邊界效應(yīng)的影響甚小此時(shí)可*按薄膜應(yīng)力進(jìn)行設(shè)計(jì)，而不必考慮邊緣應(yīng)力的影響。旋壓法加工封頭的優(yōu)點(diǎn)：設(shè)備、工裝投資較模壓法少。</p><div

style="text-indent:25px">旋壓法加工封頭的優(yōu)點(diǎn)：可生產(chǎn)模壓法難以生產(chǎn)的薄壁大直徑封頭，加工不銹鋼封頭有比較大的經(jīng)濟(jì)價(jià)值。南通Q235B封頭企業(yè)</p><p 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)線曲率變化平滑連續(xù)，故應(yīng)力分布比較均勻，對于標(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合；橢圓形封頭經(jīng)線曲率變化平滑連續(xù)，易于沖壓成型，是目前應(yīng)用較多的封頭。南通Q235B封頭企業(yè)</p><p
