1 前言 GJB 1996—94《管道用金属波纹管膨胀节通用规范》于1994年9月发布,1995年4月起实施,该标准获得了1998年度部委级军用标准化科技进步三等奖。该标准规定了军事技术装备中各种压力管道系统用金属波纹管膨胀节的分类、要求、质量保证规定、交货准备等内容,该标准适用于在管道中补偿管系设备热位移和机械位移所用的U形金属波纹管膨胀节的设计、制造和验收。标准立项时军工领域已在大量应用金属波纹管膨胀节,生产厂家多采用国标或部标生产,无统一的
1 Foreword GJB 1996-94 “Common Specification for Expansion Joints of Metallic Bellows for Piping” was released in September 1994 and implemented in April 1995, which won the third prize of 1998 Ministry of Science and Technology for Military Standardization. This standard specifies the classification, requirements, quality assurance provisions, delivery preparation and other contents of metal bellows expansion joints for various pressure piping systems in military technology and equipment. This standard is applicable to the compensation of thermal and mechanical displacement of piping equipment in pipelines U-shaped metal bellows used in the expansion joint design, manufacture and acceptance. Standard project when the field of military has been extensive use of metal bellows expansion joints, manufacturers use more GB or standard production, no uniform
