4、考慮國內(nèi)目前鋼管及管道法蘭組件生產(chǎn)和供應(yīng)的實際情況。全部執(zhí)行該標(biāo)準(zhǔn)尚有一定困難。本標(biāo)準(zhǔn)基本按照SH3405-96的規(guī)定，但作了若干修改，主要有； a） 公稱直徑DN350DN1000鋼管的外徑仍按我院現(xiàn)行規(guī)定編制，以便于與機(jī)械部法蘭（JB/T81-94JB/T86-94）配套連接。 b）考慮到在老廠改造設(shè)計中仍有可能選用小外徑鋼管，本標(biāo)準(zhǔn)補(bǔ)充列入了外徑鋼管系列，但不推薦選用。 c） 本標(biāo)準(zhǔn)列出了中國石化總公司標(biāo)準(zhǔn)石油化工企業(yè)鋼管尺寸系列（SH3405-96），當(dāng)選用該系列時，DN350須選用與SH相配套的的法蘭、管件、緊固件和墊片系列。DN300可選用SH標(biāo)準(zhǔn)，也可選用其他相配套的標(biāo)準(zhǔn)。 d）

5、 表4.0.1表4.0.4中DN300的鋼管尺寸，亦可與國外某些標(biāo)準(zhǔn)（例如ANSI標(biāo)準(zhǔn)）配套使用。但如果管子為國外訂貨，則其外徑和壁厚應(yīng)符合國外有關(guān)標(biāo)準(zhǔn)。3.0.2 有縫鋼管DN6DN150按低壓流體輸送用鍍鋅焊接鋼管（GB/T3091-93)和低壓流體輸送用焊接鋼管（GB/T3092-93）選用。DN150500按低壓流體輸送用大直徑電焊鋼管（GB/T14980-94）選用。4. 鋼管尺寸系列4.0.1 奧氏體不銹鋼無縫鋼管尺寸和理論質(zhì)量見表4.0.1。4.0.2 碳素鋼、合金鋼無縫鋼管的尺寸和理論質(zhì)量見表4.0.2。4.0.3 奧氏體不銹鋼焊接鋼管的尺寸和理論質(zhì)量見表4.0.3。4.0.4
