17、AGE 1 1 Introduction This part of the Pressure Relief Device Standards presents the minimum requirements recommended by the Compressed Gas Association, Inc. (CGA), for pressure relief devices (PRDs) being used on compressed gas storage containers constructed in accordance with the American Society o
18、f Mechanical Engineers ASME Boiler and CGA G-2.1, American National Standard Safety Requirements for the Storage and Handling of Anhydrous Ammonia (ANSI K61.1) 4. A number of states and cities have pressure vessel laws and regulations that include requirements for PRDs. Manufacturers and users are c
19、autioned that in some instances the relief devices recommended in this standard might not be acceptable unless special permission is obtained from the authority having jurisdiction. 2.2 Purpose The purpose of this standard is to complement the requirements of various regulations, codes, standards, o
20、r specifications applicable to storage containers for compressed gases. In case of conflict, the requirements of the regulations, codes, standards, or specifications of the authorities having jurisdiction over such containers shall apply. It is recommended that containers fabricated after December 3
21、1, 1995, use PRDs that meet the requirements of this edition of CGA S-1.3. CGA believes that reclosing PRDs on a container shall be able to handle all operational emergency conditions except fire and liquid displacement from a runaway fill. Where fire or liquid overfill is a credible emergency event
22、, reclosing or nonreclosing PRDs shall be provided. 3 Definitions For the purpose of this standard, the following definitions apply. 3.1 ASME Code Paragraph U-68, U-69, U-200, or U-201 of Section VIII of the Boiler and Pressure Vessel Code, 1949 Edition; or Section VIII of the Boiler and Pressure Ve
23、ssel Code, 1950 edition through the current edition, including ad- denda 1. 3.2 Combination pressure relief device Breaking pin device in combination with a pressure relief valve in which the breaking pin device is located between the container and the pressure relief valve; 1 References are shown b
24、y bracketed numbers and are listed in order of appearance in the reference section. 2 kPa shall indicate gauge pressure unless otherwise noted as (kPa, abs) for absolute pressure or (kPa, differential) for dif- ferential pressure. All kPa values are rounded off per CGA P-11, Metric Practice Guide fo
