20.37公制、美制和英制螺纹标准NPT，PT，G 都是管螺纹．NPT 是National (American) Pipe Thread 的缩写，属於美国标准的60 度锥管螺纹，用於北美地区．国家标准可查阅GB/T12716-1991 PT 是Pipe Thread 的缩写，是5 5 度密封圆锥管螺纹，属惠氏螺纹家族，多用於欧洲及英联邦国家．常用於水及煤气管行业，锥度规定为1:16．国家标准可查阅GB/T7306-2000 G 是55 度非螺纹密封管螺纹，属惠氏螺纹家族．标记为G 代表圆柱螺纹．国家标准可查阅GB/T7307-2001 另外螺纹中的1/4、1/2、1/8 标记是指螺纹尺寸的直径，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。

20.37公制、美制和英制螺纹标准NPT，PT，G 都是管螺纹．NPT 是National (American) Pipe Thread 的缩写，属於美国标准的60 度锥管螺纹，用於北美地区．国家标准可查阅GB/T12716-1991 PT 是Pipe Thread 的缩写，是5 5 度密封圆锥管螺纹，属惠氏螺纹家族，多用於欧洲及英联邦国家．常用於水及煤气管行业，锥度规定为1:16．国家标准可查阅GB/T7306-2000 G 是55 度非螺纹密封管螺纹，属惠氏螺纹家族．标记为G 代表圆柱螺纹．国家标准可查阅GB/T7307-2001 另外螺纹中的1/4、1/2、1/8 标记是指螺纹尺寸的直径，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。

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。

20.37公制、美制和英制螺纹标准NPT，PT，G 都是管螺纹．NPT 是National (American) Pipe Thread 的缩写，属於美国标准的60 度锥管螺纹，用於北美地区．国家标准可查阅GB/T12716-1991 PT 是Pipe Thread 的缩写，是5 5 度密封圆锥管螺纹，属惠氏螺纹家族，多用於欧洲及英联邦国家．常用於水及煤气管行业，锥度规定为1:16．国家标准可查阅GB/T7306-2000 G 是55 度非螺纹密封管螺纹，属惠氏螺纹家族．标记为G 代表圆柱螺纹．国家标准可查阅GB/T7307-2001 另外螺纹中的1/4、1/2、1/8 标记是指螺纹尺寸的直径，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。
