鋼管公稱直徑與內(nèi)、外徑的關系對照表

13131313鋼管公稱直徑與內(nèi)、外徑的關系對照.總則.0.1本標準規(guī)定了石油化工企業(yè)用DN10-DN2000的碳鋼素鋼、合金鋼、奧氏體不銹鋼無縫鋼管及焊接鋼管的尺寸系列。0.2本標準適用于石油化工企業(yè)中的一般鋼制管道。本標準不適用于儀表用管道。.0.3本標準代替《鋼管的公稱直徑、外徑和壁厚》(BA3-4-1-92)。.引用標準GB8163輸送液體用無縫鋼管GB9948石油裂化用無縫鋼管GB6479化肥設備用高壓無縫鋼管GB5130高壓鍋爐用無縫鋼管GB/T14976流體輸送用不銹鋼無縫鋼管GB/T3091低壓流體輸送用鍍鋅焊接鋼管GB/T3092低壓流體輸送用焊接鋼管GB/T14980低壓流體輸送用大直徑電焊鋼管SY/T5037普通流體輸送管道用螺旋埋弧焊鋼管SH3405石油化工企業(yè)鋼管尺寸系列GB3274普通碳素結(jié)構(gòu)鋼和低合金結(jié)構(gòu)鋼熱軋厚鋼板技術條件GB912普通碳素結(jié)構(gòu)鋼和低合金結(jié)構(gòu)鋼薄鋼板技術條件GB6654壓力容器用碳素鋼和低合金鋼厚鋼板GB3531低溫壓力容器用低合金厚鋼板技術條件GB5681壓力容器用熱軋鋼帶GB711優(yōu)質(zhì)碳結(jié)構(gòu)鋼熱軋厚鋼板和寬鋼帶GB713鍋爐用碳素鋼和低合金鋼板GB3280不銹鋼冷軋鋼板GB/T4237不銹鋼熱軋鋼板GB4238耐熱鋼板執(zhí)行本標準時，尚應符合上述相關標準的要求。.一般規(guī)定3.0.1中國石油化工總公司標準SH3045-96《石油化工企業(yè)鋼管尺寸系列》已頒布代替SHJ405-89并開始實施.。考慮國內(nèi)目前鋼管及管道法蘭組件生產(chǎn)和供應的實際情況。全部執(zhí)行該標準尚有一定困難。本標準基本按照SH3405-96的規(guī)定，但作了若干修改，主要有；a)公稱直徑DN350～DN1000鋼管的外徑仍按我院現(xiàn)行規(guī)定編制，以便于與機械部法蘭(JB/T81-94～JB/T86-94)配套連接。b)考慮到在老廠改造設計中仍有可能選用小外徑鋼管，本標準補充列入了外徑鋼管系列，但不推薦選用。c)本標準列出了中國石化總公司標準《石油化工企業(yè)鋼管尺寸系列》(SH3405-96)，當選用該系列時，DN≥350須選用與SH相配套的的法蘭、管件、緊固件和墊片系列。DN≤300可選用SH標準，也可選用其他相配套的標準。d) 表4.0.1～表4.0.4中DN≤300的鋼管尺寸，亦可與國外某些標準(例如ANSI標準)配套使用。但如果管子為國外訂貨，則其外徑和壁厚應符合國外有關標準。3.0.2有縫鋼管DN6～DN150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。DN150～500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碳素鋼、合金鋼焊接鋼管的尺寸和理論質(zhì)量見表4.0.4。4.0.5小外徑系列碳素鋼、合金鋼、奧氏體不銹鋼無縫鋼管的尺寸和理論質(zhì)量見表4.0.5。4.0.6有縫鋼管的尺寸和理論質(zhì)量見表4.0.6.1表4.0.6.2表4.0.6.3。4.0.7中國石化總公司標準SH3046的鋼管尺寸系列見附錄A。4.0.8鋼管的每米理論質(zhì)量可按下式計算：M=0.02466t (D-t) (4.0.8)式中：M……鋼管質(zhì)量，kg/mt……鋼管壁厚，mmD……鋼管外徑，mm對于奧氏體不銹鋼鋼管，按上式計算后再乘以1.015。精確計算時，各種奧氏體鋼的密度見GB/T14976-94中的表5。
