英制螺纹 规格 牙型 对照表
55°圆柱管螺纹的型式和尺寸RC2英寸锥管螺纹，每英寸11牙，螺距=25.4/11即2.309，牙高（深）=2.309×0.64即1.479，锥度是固定的即1：16R等于1/32乘以长度1/32意思是，锥螺纹的锥度是1：16 ，单边就是1：32长度意思是：定位点加有效长度比如我定位3.0，有效长度是12.0 R=1/32 X （3+12）=0.46875 1、密封管螺纹（R） 英制密封管螺纹的基本尺寸及其公差 配合方式 英制密封管螺纹有两种配合方式：圆柱内螺纹与圆锥外螺纹组成“柱/锥”配合；圆锥内螺纹与圆锥外螺纹组成“锥/锥”配合. 欧洲国家主要采用“柱/锥”配合螺纹；而欧洲以外国家则主要采用“柱/锥”配合螺纹.两种螺纹的检验量规存在一定不同；目前的ISO英制密封管螺纹量规标准（ISO 7-2：2000）是按“柱/锥”配合体系设计的.编辑本段密封管螺纹的标记 英制密封管螺纹的完整标记由螺纹特征代号、螺纹尺寸代号和旋向代号组成. 英制密封圆柱内螺纹的特征代号为：RP； 英制密封圆锥内螺纹的特征代号为：RC； 英制密封圆锥外螺纹的特征代号为：R1（与英制密封圆柱内螺纹配合使用）； R2（与英制密封圆锥内螺纹配合使用）； 左旋螺纹的旋向代号为LH；右旋螺纹的旋向代号省略不标. 对密封管螺纹，利用RP/R1，RC/R2分别表示“柱/锥”和“锥/锥”螺纹副. 2、非密封管螺纹 英制非密封管的基本尺寸及其极限偏差 标记: 英制非密封管螺纹的完整标记由螺纹特征代号，螺纹尺寸代号，中径公差等级代号和旋向代号组成. 英制非密封圆柱螺纹的特征代号为：G 对英制非密封圆柱内螺纹，其中径公差等级代号省略不标；而英制非密封圆柱外螺纹的中径公尺等级代号分别为A和B. 左旋螺纹的旋向代号为LH；右旋螺纹的旋向代号省略不标. 当表示英制非密封管螺纹的螺纹副时，仅标注外螺纹的标记代号. 示例： 尺寸代号为2的右旋，非密封圆柱内螺纹：G2 尺寸代号为3的A 级，右旋，非密封圆柱外螺纹：G3A 尺寸代号为4的B 级，左旋，非密封圆柱外螺纹：G4B-LH 尺寸代号为2的右旋，非密封圆柱内螺纹与A级圆柱外螺纹组成的螺纹副：G2A 加工内孔螺纹的是管螺纹丝锥加工外螺纹的有板牙。
