g="#src_7,#tran_7" id="src_7" style="margin: 0px; padding: 0px; border: 0px; outline: 0px; color: rgb(67, 67, 67);">但可以看出A系列的大外徑僅限于DN200以下，在DN300以上其直徑反而小于公制管。
g="#src_8,#tran_8" id="src_8" style="margin: 0px; padding: 0px; border: 0px; outline: 0px; color: rgb(67, 67, 67);"> 很多情況下兩者差別是很大的：如DN100時(shí)差了6.3mm，大直徑時(shí)差別達(dá)20mm以上
