Metallic Connections for Fluid Power and General Use - Part 3: NPTF Pipe Adapters and NPSM Adapter Unions 流体动力和一般用途的金属连接.第3部分:NPTF管接头和NPSM接头活接头

发布日期： 2023-12-13

SAE J514的本部分涵盖NPTF管接头和30°NPSM接头活接头的通用规范和尺寸规范。这些配件适用于工业设备和商业产品的液压系统。这些配件能够在表6规定的工作压力下运行的液压系统中提供防漏、全流量连接。由于许多因素会影响液压系统将要或不会令人满意地运行的压力，因此表6中所示的值不应被视为保证的最小值。对于任何应用，建议用户和配件制造商进行充分的测试和审查，以确保性能水平是安全和令人满意的。

This part of SAE J514 covers general and dimensional specifications for NPTF pipe adapters and 30 degree NPSM adapter unions. These fittings are intended for general application in hydraulic systems on industrial equipment and commercial products.These fittings are capable of providing leak-proof, full-flow connections in hydraulic systems operating at working pressures as specified inTable 6. Since many factors influence the pressure at which a hydraulic system will or will not perform satisfactorily, the values shown inTable 6should not be construed as a guaranteed minimum.For any application, it is recommended that sufficient testing be conducted and reviewed by both the user and fitting manufacturer to assure that performance levels will be safe and satisfactory.
