28、尺寸的直径，单位是英吋行内人通常用分来称呼螺纹尺寸，一吋等於8分，1/4吋就是2分，如此类推G好像就是管螺纹的统称(Guan)，55，60度的划分属于功能性的，俗称管圆。即螺纹由一圆柱面加工而成。ZG俗称管锥，即螺纹由一圆锥面加工而成，一般的水管接头都是这样的，老国标标注为Rc-公制螺纹用螺距来表示，美英制螺纹用每英寸内的螺纹牙数来表示，这是它们最大的区别，公制螺纹是60度等边牙型，英制螺纹是等腰55度牙型，美制螺纹60度。公制螺纹用公制单位，美英制螺纹用英制单位。管螺纹主要用来进行管道的连接，其内外螺纹的配合紧密，有直管与锥管两种。公称直径是指所连接的管道直径，显然螺纹大径比公称直径大。1/
