style="text-indent:25px">封頭標(biāo)注在圖樣上的厚度。當(dāng)然在使用封頭的時(shí)候，必須要明確其的有效厚度，所謂有效厚度指的是名義厚度減去腐蝕裕量和鋼材厚度負(fù)偏差的厚度。這些不同厚度參數(shù)之間存在著一定的關(guān)系。并且主要是以這些厚度參數(shù)來計(jì)算出封頭產(chǎn)品的投料厚度，也就是毛坯厚度。在電廠施工中，會(huì)使用到很多的大口徑管道，比如補(bǔ)給水管、循環(huán)水管等。根據(jù)機(jī)組容量等級(jí)的不同，管道口徑位于DN1000~5500之間。電力建設(shè)管道施工需要滿足相關(guān)的規(guī)范和要求，此時(shí)在選用大尺寸橢圓封頭產(chǎn)品的時(shí)候就會(huì)面臨著較大的施工困難。封頭的使用時(shí)要遵守一定的規(guī)范的。浙江吸收塔封頭廠家聯(lián)系方式</p><p
