style="font-family:宋體;font-size:12pt;mso-bidi-font-family:宋體;mso-font-kerning:0pt;">及有關(guān)封頭規(guī)范的厚度界說不甚合理，首要體現(xiàn)在容器和封頭成形后的厚度要求上，黑龍江封頭，黑龍江封頭，對凸形封頭和熱卷筒的成形厚度要求不得小于名義厚度減鋼板負(fù)誤差（<span>δn-C1</span>），由此或許導(dǎo)致規(guī)劃和制作兩次在規(guī)劃厚度的基礎(chǔ)上添加厚度以確保成形厚度。為此，曾經(jīng)提出了**小成形厚度的概念：<span>"</span>熱卷圓筒或凸形封頭加工成形后需確保的厚度，其值不小于規(guī)劃厚度<span>"</span>。也就是說規(guī)劃者應(yīng)在圖紙上標(biāo)示名義厚度和**小成形厚度（即規(guī)劃厚度<span>δd</span>），這樣使得制作單位可根據(jù)制作工藝和原規(guī)劃的規(guī)劃圓整量決定是否再加制作減薄量。這種厚度的界說和標(biāo)示是截止<span>2013</span>年世界壓力容器界的流行辦法，有其合理性，但在我國現(xiàn)行規(guī)范中有以下兩個問題需解決。</span>
