油氣工程設(shè)計中鋼管外徑和壁厚的選用.doc

油氣工程設(shè)計中鋼管外徑和壁厚的選用地面工藝設(shè)計所 薛道才一、油氣工程設(shè)計執(zhí)行規(guī)范目前，國內(nèi)的油氣工程設(shè)計按其內(nèi)容不同分別執(zhí)行下列規(guī)范：1、輸氣管道工程設(shè)計規(guī)范 GB502512、輸油管道工程設(shè)計規(guī)范 GB50253；3、油氣集輸設(shè)計規(guī)范 GB50350；4、城鎮(zhèn)燃?xì)庠O(shè)計規(guī)范 GB50028；5、石油庫設(shè)計規(guī)范 GB50074；6、石油儲備庫設(shè)計規(guī)范 GB50737；7、汽車加油加氣站設(shè)計與施工規(guī)范GB50156。二、鋼管規(guī)格和材料性能執(zhí)行規(guī)范對于不同的油氣工程設(shè)計，其工藝管道凡選用國產(chǎn)鋼管的，其規(guī)格與材料性能應(yīng)分別符合下述現(xiàn)行國家標(biāo)準(zhǔn)（詳見附表1）：1、石油天然氣工業(yè)管線輸送系統(tǒng)用鋼管 GB/T9711；2、輸送流體用無縫鋼管 GB/T8163；3、高壓鍋爐用無縫鋼管 GB5310；4、化肥設(shè)備用高壓無縫鋼管 GB6479；5、低壓流體輸送用焊接鋼管 GB/T3091。三、鋼管尺寸、外形、重量及允許偏差執(zhí)行規(guī)范每一個鋼管標(biāo)準(zhǔn)中分別規(guī)定了選擇鋼管尺寸、外形、重量的不同標(biāo)準(zhǔn)，共計有下列標(biāo)準(zhǔn)（詳見附表1）：1、平端鋼管(焊接、無縫)尺寸和單位長度重量表 ISO 42002、焊接和無縫軋制鋼管 ASME B36.10M3、無縫鋼管尺寸、外形、重量及允許偏差 GB/T173954、焊接鋼管尺寸及單位長度重量 GB/T21835四、碳鋼鋼管外徑和壁厚的標(biāo)準(zhǔn)化數(shù)值匯總現(xiàn)將上述4個鋼管尺寸、外形標(biāo)準(zhǔn)的外徑和壁厚標(biāo)準(zhǔn)化數(shù)值匯總在一起（詳見表2），供設(shè)計人員參考選用。五、石油天然氣工業(yè)管線輸送系統(tǒng)用鋼管GB/T9711中給定鋼管外徑和壁厚標(biāo)準(zhǔn)選用的討論石油天然氣工業(yè)管線輸送系統(tǒng)用鋼管GB/T9711-2011于2012年6月1日開始執(zhí)行，但標(biāo)準(zhǔn)規(guī)范中取消了鋼管外徑、壁厚和重量的數(shù)據(jù)，鋼管規(guī)定外徑和規(guī)定壁厚的選用要求執(zhí)行ISO 4200和ASME B36.10M標(biāo)準(zhǔn)，根據(jù)附表2中數(shù)據(jù)可以看出：1、平端鋼管(焊接、無縫)尺寸和單位長度重量表ISO 4200的鋼管外徑系列和壁厚系列基本類同于無縫鋼管尺寸、外形、重量及允許偏差GB/T17395和焊接鋼管尺寸及單位長度重量GB/T21835。2、ISO 4200、GB/T17395和GB/T21835的壁厚晉級比較圓整和有規(guī)律性，如DN200管徑的壁厚：ISO 4200： 5.0、5.4、5.6、6.3、7.1、8.0、8.8、10.0、11.0；GB/T17395：6.0、6.5、7.0、7.5、8.0、8.5、9.0、9.5、10.0；GB/T21835：6.3、7.1、8.0、8.8、10.0、11.0、12.5、14.2。此三個標(biāo)準(zhǔn)的壁厚系列屬于常規(guī)管材系列，無論用量多少市面上都比較容易采購，所以適合于油氣站場工程和油氣田集輸工程設(shè)計中選用；3、焊接和無縫軋制鋼管ASME B36.10M鋼管外徑系列齊全，在DN500DN2000范圍內(nèi)增加了DN550、DN650、DN750、DN850、DN1050、DN1150、DN1300、DN1700、DN1900規(guī)格。而且壁厚晉級比較理論計算化，如8.74、9.53、10.31、11.13、11.91、12.70，且壁厚尺寸保留了小數(shù)點(diǎn)后兩位，更適合于大口徑、長距離的輸送管道工程中大批量管材選用。六、結(jié)束語1、低壓流體的管道壁厚系列可執(zhí)行焊接鋼管尺寸及單位長度重量GB/T21835；2、DN400的站場或油氣集輸中高壓管道壁厚系列可執(zhí)行無縫鋼管尺寸、外形、重量及允許偏差GB/T17395；3、DN400的站場或油氣集輸中高壓管道壁厚系列可執(zhí)行平端鋼管(焊接、無縫)尺寸和單位長度重量表ISO 4200；4、油氣長輸管道壁厚系列可執(zhí)行焊接和無縫軋制鋼管ASME B36.10M。附表1
