管材扩口

[中文适用范围]： 本SAE标准规定了用于SAE J512、SAE J513、SAE J514和ISO 8434-2连接器的37度和45度单双喇叭口的规格和性能要求。本文档描述的喇叭口适用于SAE金属管材料。具体工作压力的壁厚选择、与连接器配合的适当螺纹啮合长度以及其他相关标准的考虑应由用户负责。液压管道的适用标称参考工作压力请参考SAE J1065和ISO 10763。 [外文原描述]： This SAE Standard covers specifications and performance requirements for 37-degree and 45-degree single and double flares for tube ends intended for use with SAE J512, SAE J513, SAE J514, and ISO 8434-2 connectors. The flares described in this document are intended for use with SAE metallic tube materials. Considerations such as the effects of wall thickness selection for specific working pressures, identifying the appropriate length of thread engagements for specific applications with mating connectors, and other associated criteria shall be the responsibility of the user. For applicable nominal reference working pressures for hydraulic tubing, refer to SAE J1065 and ISO 10763. In an effort to standardize within a global marketplace and ensure that companies can remain competitive in an international market, it is the intent of this document to promote the use of metric tube and connector sizes, which will: Lead to one global system. Guide users to a preferred system. Reduce complexity. Eliminate inventory duplications.
