管螺纹尺寸对照表全
管螺纹尺寸对照表全管螺纹尺寸对照表全,是涉及到管道工程常见的一种工具,也是在安装、维护管道设备过程中最常用的一种规格型号。
管螺纹在管道工程中的使用十分重要,分为内螺纹和外螺纹两种。
内螺纹通常在管道连接部分进行固定,而外螺纹则通过旋转连接与其他管道或设备件进行连通。
管螺纹尺寸对照表主要用于管道工程的选择,可用于管件的尺寸检测、校准、安装等相关操作。
由于不同的螺纹尺寸和型号在管道工程中所承受的工作压力不同,因此必须选择适合的螺纹尺寸进行安装,以保证管道的稳定性和安全性。
以下是管螺纹尺寸对照表全,便于工程师们在进行管道安装时有所参考。
一、管螺纹系列尺寸1、英制螺纹系列英制螺纹(Unified Thread Standard,简称UTS)又称美制螺纹,是世界上应用最广泛的标准螺纹之一。
英制螺纹系列的特点是双角度为60度,以便于使用常用的60度加工刀具,其中螺纹角度为55度。
英制螺纹的尺寸包括两个基本要素:螺距和外径。
在通常情况下英制螺纹的螺距为每英寸的线数或根数。
如表1所示(以UNC和UNF为例),英制螺纹系列的螺纹外径小于或等于2英寸时,用六角法就可以拧紧。
而螺纹外径超出2英寸时则一般用周边固定螺栓接头来拧紧。
表1分类|型号|常用规格UNC|粗牙联合螺纹Unified Coarse Thread|#4~4英寸UNF|细牙联合螺纹Unified Fine Thread|#10~4英寸UNEF|极细牙联合螺纹Unified Extra FineThread|#4~1.5英寸UNW|特粗牙联合螺纹Unified National Extreme Thread|1.5~4英寸UNS|特粗牙联合螺纹Unified Special Thread|#10~4英寸UNJ|特紧牙联合螺纹Unified National JetThread|3/8~3英寸2、公制螺纹系列公制螺纹是以公制毫米为单位的螺纹。
其特点是角度为60度,常用于汽车、航空、电子等行业中,具有世界认可的国际标准。
