油气工程设计中钢管外径和壁厚的选用

1、油气工程设计中钢管外径和壁厚的选用地面工艺设计所 薛道才一、油气工程设计执行规范目前，国内的油气工程设计按其内容不同分别执行下列规范：1、输气管道工程设计规范GB502512、输油管道工程设计规范GB50253；3、油气集输设计规范GB50350；4、城镇燃气设计规范GB50028；5、石油库设计规范GB50074；6、石油储备库设计规范GB50737； 7、汽车加油加气站设计与施工规范 GB50156。 二、钢管规格和材料性能执行规范对于不同的油气工程设计， 其工艺管道凡选用国产钢管的， 其规格与材料性能应分 别符合下述现行国家标准（详见附表 1）：1、石油天然气工业管线输送系统用钢管GB/

2、T9711 ；2、输送流体用无缝钢管GB/T8163 ；3、高压锅炉用无缝钢管GB5310；4、化肥设备用高压无缝钢管GB6479；5、低压流体输送用焊接钢管GB/T3091 。三、钢管尺寸、外形、重量及允许偏差执行规范每一个钢管标准中分别规定了选择钢管尺寸、外形、重量的不同标准，共计有下列标准（详见附表 1）：1、平端钢管 （焊接、无缝 ）尺寸和单位长度重量表ISO 42002、焊接和无缝轧制钢管ASME B36.10M3、无缝钢管尺寸、外形、重量及允许偏差GB/T173954、焊接钢管尺寸及单位长度重量GB/T21835四、碳钢钢管外径和壁厚的标准化数值汇总现将上述 4 个钢管尺寸、外形标

3、准的外径和壁厚标准化数值汇总在一起 （详见表 2），供设计人员参考选用五、石油天然气工业管线输送系统用钢管 GB/T9711 中给定钢管外径和壁厚标准 选用的讨论石油天然气工业管线输送系统用钢管GB/T9711-2011于2012年6月1日开始执行，但标准规范中取消了钢管外径、壁厚和重量的数据，钢管规定外径和规定壁厚的选用要 求执行ISO 4200和ASME B36.10M标准，根据附表2中数据可以看出：1、平端钢管 （焊接、无缝 ）尺寸和单位长度重量表 ISO 4200的钢管外径系列和壁 厚系列基本类同于无缝钢管尺寸、外形、重量及允许偏差 GB/T17395 和焊接钢管尺寸 及单位长度重量

4、GB/T21835。2、ISO 4200、GB/T17395 和 GB/T21835 的壁厚晋级比较圆整和有规律性， 如 DN200 管径的壁厚：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此三个标准的壁厚系列属于常规管材系列，无论用量多少市面上都比较容易采购， 所以适合于油气站场工程和油气田集输工程设计中选用；3、焊接和无缝轧制钢管ASME B36.10

5、M钢管外径系列齐全，在DN500DN2000范围内增加了 DN550、DN650、DN750、DN850、DN1050、DN1150、DN1300、DN1700、DN1900规格。而且壁厚晋级比较理论计算化，如、12.70 且壁厚尺寸保留了小数点后两位， 更适合于大口径 长距离的输送管道工程中大批量管材选 用。六 结束语1、低压流体的管道壁厚系列可执行焊接钢管尺寸及单位长度重量GB/T21835；无缝钢管尺寸 外形平端钢管 （焊接、无缝）2、 DN400的站场或油气集输中高压管道壁厚系列可执行重量及允许偏差 GB/T17395；3、 DN400的站场或油气集输中高压管道壁厚系列可执行尺寸和单位
