ANSI/ASME B1.20.2M-2006 60°管端螺纹.一般用途

Specifies the designations, dimensions, and tolerances and establishes a verification system for 60 degree included angle pipe threads. It is applicable for general purpose pipe and fitting connections. Where pressure tight joints are required, it is intended that taper pipe threads conforming to this Standard be made up wrench-tight with a sealant. To prevent galling on certain piping materials such as stainless steel, the sealant should contain a lubricant. Internal parallel (straight) pipe threads, series NPSC, are used with external taper pipe threads, series NPT. Internal taper pipe threads, series NPT, are used with external taper pipe threads, series NPT.

CEN EN 10226-2-2005 在螺纹上制成压力密封接头的管螺纹 第2部分：锥度、外螺纹和锥度内螺纹 尺寸、公差和名称

This European Standard specifies the requirements for thread form, dimensions, tolerances and designation for jointing pipe threads, sizes 1/16 to 6 inclusive, for joints made pressure-tight by the mating of the threads. These threads are taper external and taper internal and are intended for use with pipes suitable for threading and for valves, fittings or other pipeline equipment interconnected by threaded joints. An appropriate thread sealant or jointing compound should be used on the thread to ensure pressure-tight joints. NOTE 1 Threaded joints using taper external threads and parallel internal threads are detailed in EN 10226-1. NOTE 2 The requirements for taper external threads are identical in EN 10226-1 and EN 10226-2. NOTE 3 For pipe threads where pressure-tight joints are not made on the threads see EN ISO 228-1. NOTE 4 EN 10226-3 gives details of recommended gauging systems for the verification of thread dimensions and thread form.
