1.1 本规范涵盖了通过机械成型工艺制造的非增强挤压三通接头的管材和尺寸。术语“挤压三通连接”适用于对接焊或承插焊连接。本规范涉及导致焊接或钎焊的成型过程。 1.2 非钢筋挤压管三通接头是三通管件、喷嘴和其他焊接接头的替代品。 1.3 非增强挤压管三通接头已广泛用于海洋、工艺管道、食品、制药和类似行业的系统。 1.4 挤压三通接头将按照规范进行焊接 F722 . 三通接头的钎焊应符合ASME B31.5的要求。 1.5 以国际单位制表示的数值应视为标准值。括号中给出的值是英寸-磅单位的数学转换，仅供参考，不被视为标准值。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

1.1 This specification covers the pipe materials and dimensions for producing non-reinforced extruded tee connections manufactured by mechanical forming processes. The term “extruded tee connection” applies to butt-weld or socket-weld connections. This specification refers to the forming process that leads to welding or brazing. 1.2 The non-reinforced extruded pipe tee connection is an alternative to the tee fittings, nozzle, and other welded connections. 1.3 The non-reinforced extruded pipe tee connection has been widely used for systems in the marine, process piping, food, pharmaceutical, and similar industries. 1.4 The extruded tee connection will be welded in accordance with Specification F722 . Brazing of tee connections will be in accordance with ASME B31.5. 1.5 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
