1. 管子   大(da)外徑(jing)(jing)(jing)系列（JIS G3454、JIS G3458、JIS G3459）與ASME大(da)多數(shu)相同；無(wu)縫鋼管公稱直徑(jing)(jing)(jing)：DN6～DN650；用管子表號“Sch”表示壁厚：碳鋼及合(he)金鋼（JIS G3454、JIS G3458):Sch10、Sch20、Sch30、Sch40、Sch60、Sch80、Sch100、Sch120、Sch140、Sch160；不(bu)銹鋼（JIS G 3459）：Sch5s、Sch10s、Sch20s、Sch40s、Sch80s、Sch120s、Sch160s。焊接鋼管公稱直徑(jing)(jing)(jing)：DN350～DN2000。

  2. 管(guan)法(fa)蘭   管(guan)法蘭(lan)JIS B2201、JIS B2220等自成體系(xi)，既不(bu)屬(shu)于“美(mei)式(shi)(shi)法蘭(lan)”，也不(bu)屬(shu)于“歐式(shi)(shi)法蘭(lan)”。公(gong)稱直徑：DN10～DN1000；公(gong)稱壓力(li)等級(ji)：2K、5K、10K、16K、20K、30K、40K、63K，其(qi)對應的許用壓力(li)值（120℃時的）見表(biao)16.8。法蘭(lan)密封面形式(shi)(shi)光滑(hua)面、大(da)凸臺面、小凸臺面、凹凸面、榫槽(cao)面5種。法蘭(lan)形式(shi)(shi)有平焊(han)式(shi)(shi)、承插焊(han)式(shi)(shi)、對焊(han)式(shi)(shi)、螺紋連(lian)接式(shi)(shi)、松套(tao)式(shi)(shi)及(ji)法蘭(lan)蓋6種。JIS標(biao)準體系(xi)與(yu)ASME和(he)DIN等都不(bu)能配套(tao)使用。為了(le)彌補這個缺陷，日本石(shi)油(you)學會編(bian)制了(le)一套(tao)JPI標(biao)準，它基本上等效采用了(le)ASME、API標(biao)準體系(xi)，故能與(yu)ASME互(hu)換(huan)。
