管道和管道之间的间距表.docx

管道和管道之间的间距表1总则1.0.1本标准适用于不保温管道和保护层为镀锌铁皮或铝合金板的保温架空管道。表中数值为架空管道的最小间距。1.0.2本标准根据中国石油化工总公司标准石油化工企业管道设计通则(SHJ12-89)中第三章第二节管道间距的规定。并按院标设备和管道隔热材料及其厚度选用规定(BA2-3-9-94)中的管道保温经济厚度选用表(表-4)所规定的保温材料及其厚度进行计算的管道最小间距。1.0.3执行本标准时，尚应符合现行有关标准规定的要求。104本标准代替管道间距表(BA3-3-6-89)。2管道间距的确定2.0.1本标准依据机械行业标准凸面对焊钢制管法兰(JB/)和凹凸面对焊钢制管法兰(JB/)中系列1法兰外径计算管道间距。202在管架上并排布置的管道不论有无保温，净距均取50mm,法兰外缘与相邻的净距取25mmo2.1
