水管气管管道常用标准尺寸对照：1英寸=2.54厘米把1英的1分管到7分管,更小的尺寸用1/16、1/32、1/64来表示，单位还是英寸。

如果分母和分子能够约分（如分子是2、4、8、16、32）就应该约分。

英寸的表示是在右上角打上两撇，如1/2"如DN25（25mm，下同）的水管就是英制1"的水管，也是解放前的8分水管。

DN15的水管就是英制1/2"的水管，也是解放前的4分水管。

如DN20的水管就是英制3/4"的水管，也是解放前的6分水管。

一、尺寸：见附表寸分成8等分；1/8 1/4 3/8 1/2 5/8 3/4 7/8 英寸。

相当于通常说二、标准：有英制标准和国际标准两种。

三、材质：材质就有很多，根据不同的需要。

1、塑料管：有PVC、UPVC、PPR、PPR稳态塑铝合金、铝塑管、玻纹管、PE管等。

2、金属管：镀锌管、不锈钢管、不锈钢衬塑管、薄壁不锈钢管、镀锌衬塑管、铜管、铸铁管等。

我国水管的规格均采用我国法定单位的公称直径来标称的。

如DN20，就是表示公称直径20毫米的镀锌水管。

镀锌水管的系列有：DN15、DN20、DN25、DN32、DN4O、DN50、DN65、DN80、DN100、......等。

你说的几分几分的名称，是解放前我国落后，没有自己的规格和单位，就沿用了英国的单位。

英国的单位是：1英尺（ft）=12英寸 1英寸（in）=1000英丝（mil）。

其中水管的规格是英寸的分数，刚好是把一英寸分成了八份就好表示水管的规格，就创造了一个英分的单位。

其实没有英分这个单位，而是用分数带上英寸来表示1英寸以下的尺寸。

把英寸分成8分，应该是这样说：1/8英寸1/43/81/25/83/47/8相当于常说的1分到7分,更小的尺寸用1/16、1/32、1/64来表示，单位还是英寸。

如果分母和分子能够约分，如分子是2、4、8、16、32时如果能够约分，就应该约分。
