1、SAE J518 CODE 61 3000PSI 标准法兰 与 GS-HYDRO 3000PSI 法兰的应用区别 GS-HYDRO 产品遵守 SAE J518 CODE61 62 进行制作产品，但是 SAE J518 CODE 61 62 中对于 3000PSI 和 6000PSI 法兰的理解和 ASME B16.5 中法兰的应 用压力理解相似，1500LB 磅级和 3000PSI 压力等级的意思一样，针对不同的温 度和管法兰的口径下，可以承受不同的压力，并不是所有的 3000PSI 级别的法兰 都能够承受 3000PSI 的工作压力。 SAE J518 CODE61 中的法兰尺寸： GS H
2、YDRO 的法兰尺寸： 举例说明：SAE J518 CODE 61 2 1/2” 法兰尺寸： 尺寸 SAE J518 CODE 61 2 1/2”GS 3000PSI 法兰尺寸 法兰厚度 19MM 40MM 外形尺寸 114*109 114*109 螺栓孔尺寸 50.8*88.9 50.8*88.9 螺栓孔直径 13.49 13.49 螺栓直径 M12 M12 O 型槽尺寸 外径 76.33-76.07MM 宽：3.94-4.45MM- 大口径用的组合垫圈比较 多。 O 型圈尺寸 232（3.53MM） 最大工作压力 172BAR 210BAR 得出结论：除了厚度不一致，其他的均一致。按照 S
3、AE J518 CODE 61 标准 做的法兰不能用于工作压力为 3000PSI 的环境下，而 GS 的法兰就可以用在 3000PSI 压力系统中。 在现实的液压系统中，国外来的 3000PSI 的系统中有应用 2 1/2”的 GS-HYDRO 的法兰，我们要与他们连接，我们还不能用 2 1/2”的重型法兰，因 为螺栓孔的尺寸也不合适。 解决方案 1：制作非标的法兰压板，厚度增加，重新选择长的螺栓。按照 GS 的尺寸做，就不会有错误了，所以说还得跟着名牌做，安全系数都高。 解决方案 2：两边都选择 ISO6164-2 的方法兰和圆法兰或者选择 SAE J518 CODE 62 中的法兰能够配对
4、使用。 解决方案 3：两边选择 ASME B16.5 中的 1500LB 中的法兰，ASTM A105 的 普通材料，可以耐压 250BAR，在-29-50工况。 SAE Technical Standards Board Rules provide that: “This report is published by SAE to advance the state of technical and engineering sciences.

JUN93 Issued1952-02 Revised1993-06 Superseding J518 APR91 HYDRAULIC FLANGED TUBE, PIPE, AND HOSE CONNECTIONS, FOUR-BOLT SPLIT FLANGE TYPE ForewordThis Reaffirmed Document has been changed only to reflect the new SAE Technical Stand
8、ards Board Format. 1.ScopeThis SAE Standard covers complete general and dimensional specifications for the flanged heads and split flange clamp halves applicable to four-bolt split flange type tube, pipe, and hose connections with appropriate references to the O-ring seals and attaching components u
9、sed in their assembly. (See Figures 1 and 2.) Also included are recommended port dimensions and port design considerations. 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 inte
10、nded 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 A HOSE ASSEMBLY COMPRISING SAE J518 HOSE CONNECTIONS AND SAE J517 HOSE SHALL NOT EXCEED THE LOWER OF THE TWO WORKING PRESSURE
11、RATED VALUES. Flanged heads shall be as specified in Figure 3 and Table 1. Split flange clamp halves shall be as specified in Figure 4 and Table 1. Port dimensions and spacing shall be as specified in Figure 5 and Table 2. O-ring seals, having nominal dimensions as indicated in Table 1, are used in
12、conjunction with these connections. They shall conform to the seals specified in SAE J120, Table on Dimensions and Tolerances. Bolts for use with these connections shall be of the sizes and lengths indicated in Table 1. They shall be of SAE Grade 5 material or better as specified in SAE J429. Socket
13、 head cap screws of SAE Grade 5 material or better are acceptable. Lock washers, if used, shall be in accordance with the light spring lock washers specified in SAE J489, Dimensions of Light, Medium, Heavy, Extra Heavy, and Hi Collar Spring Lock Washers, and of sizes applicable to the corresponding
14、bolts. The following general specifications supplement the dimensional data contained in Table 1 with respect to all unspecified detail.
