55°圆锥管螺纹型式和尺寸表
55°圆锥管螺纹型式和尺寸表（原创实用版）目录I.55°圆锥管螺纹的概述II.55°圆锥管螺纹的尺寸表III.55°圆锥管螺纹的应用IV.55°圆锥管螺纹与其他管螺纹的区别正文I.55°圆锥管螺纹的概述55°圆锥管螺纹是一种广泛应用于管道连接的螺纹类型，其螺纹角度为 55 度，具有密封性能好、连接牢固等优点。
这种螺纹型式适用于管径范围较大的管道，其尺寸表包括了螺纹的基本尺寸、牙型高度、圆弧尺寸和底孔尺寸等参数。
II.55°圆锥管螺纹的尺寸表55°圆锥管螺纹的尺寸表中，螺纹代号为基本尺寸英寸，大径 mm，螺距 mm，每英寸牙数 tpi，中径 mm，小径外螺纹 mm，牙型高度 mm，圆弧尺寸 mm，底孔尺寸 mm。
例如，55 圆锥管螺纹型式和尺寸表中，螺纹代号为 1/8，大径为 16，螺距为 30.907，每英寸牙数为 21，中径为9.728，小径外螺纹为 8，牙型高度为 1.157，圆弧尺寸为 1.337，底孔尺寸为 11.142。
III.55°圆锥管螺纹的应用55°圆锥管螺纹广泛应用于石油、化工、水处理等领域的管道连接，其密封性能好、抗拉强度高、安装方便等优点得到了广大用户的认可。
此外，55°圆锥管螺纹还适用于一些特殊场合，如高温、高压等环境下的管道连接。
IV.55°圆锥管螺纹与其他管螺纹的区别55°圆锥管螺纹与其他管螺纹的主要区别在于螺纹角度、尺寸和密封性能等方面。
例如，与公制螺纹相比，55°圆锥管螺纹的螺纹角度更大，密封性能更好；与美制螺纹相比，55°圆锥管螺纹的尺寸更接近公制尺寸，便于互换和连接。
