This document will establish standard design criteria for this product category on future designs. 1. SCOPE This SAE standard outlines general and dimensional specifications for Code 6

7、1 flange clamps for use in low pressure applications with J518-1 connections. For port dimensions, port design considerations, and flange head dimensions, please refer to SAE J518-1. The rated working pressure of an assembly shall not exceed the least of all the component working pressure rated valu

8、es. The following general specifications supplement the dimensional data contained in the tables with respect to all unspecified detail. Parts manufactured to this standard are also compatible with ISO 6162-1 port connections and flange heads. 2. REFERENCES 2.1 Applicable Documents The following pub

24、AL RECOMMENED TORQUE VALUES TO AVOID BREAKING THE FLANGE CLAMP DURING INSTALLATION Refer to SAE J2593 for installation instructions. a. Type 2 connections shall not be used for new design. b. Minimum Burst Pressure = Working Pressure X 4. c. Coarse pitch thread in accordance with ISO 261 and ISO 724

25、 d. Screw thread lengths calculated for steel into steel; use of other materials can require different screw lengths. e. These recommended torque values were arrived at by using lubricated screws with a torque coefficient (T = KDF) of 0.17. Net tightening torque depends on many factors, including l

26、ubrication, coating, and surface finish. f. Coarse pitch thread in accordance with ISO 263 and ISO 725 (UNC-2A for screw threads, UNC-2B for port threads). g. ASME B18.22.1 Type B Narrow (HV300) washers sized by matching to the inch screw can be substituted except for the DN 32 (-20) size. To avoid

27、possible interferences, do not substitute for the DN 32 (-20) size. Use of the specified washers might not be compatible with older versions of SAE J518. h. Clamp Load is the design preload necessary to achieve a minimum 4:1 design factor. Torque values are influenced by many factors such as variati

28、ons of friction (both thread and under the head) which may vary due to both design and application conditions.
