本SAE标准涵盖了代码61公制（1型）和英制（2型）法兰头、法兰夹（FC和FCM）和分体式法兰夹（FCS和FCSM）的一般和尺寸规范，适用于四螺杆法兰型管、管道和软管连接。还包括推荐的端口尺寸和端口设计注意事项。2型（英寸）法兰夹具和分离式法兰不适用于新设计。 指定的带凸缘的头部被结合到具有用于连接管、管道或软管的合适装置的配件中，以提供连接端。这些连接旨在应用于液压系统、工业和商业产品中，其中期望避免使用螺纹连接。 组件的额定工作压力不得超过所有部件工作压力额定值中的最小值。以下通用规范补充了表中包含的所有未指定细节的尺寸数据。按照该标准制造的零件可与ISO 6162-1互换，并且可以提供符合任一标准的连接器。

This SAE Standard covers general and dimensional specifications for the Code 61 metric (Type 1) and inch (Type 2) flanged heads, flange clamps (FC and FCM), and split flange clamps (FCS and FCSM) applicable to four-screw flange type tube, pipe, and hose connections. Also included are the recommended port dimensions and port design considerations. Type 2 (inch) flange clamps and split flanges are not for new design. The flanged heads specified are incorporated into fittings having suitable means for attachment of tubes, pipes, or hoses to provide connection ends. These connections are intended for application in hydraulic systems, on industrial and commercial products, where it is desired to avoid the use of threaded connections. The rated working pressure of an assembly shall not exceed the least of all the component working pressure rated values. The following general specifications supplement the dimensional data contained in the tables with respect to all unspecified detail. Parts manufactured to this standard are interchangeable with ISO 6162-1 and connectors to either standard can be supplied.
