本标准规定了锻铜和锻铜合金、焊点、无缝配件的规范，这些配件设计用于符合ASTM B88（水和一般管道系统）、B280（空调和制冷服务）和B819（医用气体系统）的无缝铜管，以及拟用符合ASTM B32的焊接材料组装的配件，符合AWS A5的钎焊材料。8或符合ASME B1的锥形管螺纹。20.1. 本标准与ASME B16相结合。18，包括铸铜合金压力管件。它提供了适合焊接的装配端的要求。本标准涵盖压力温度额定值、端部连接的缩写、管件开口的尺寸和指定方法、标记、材料、尺寸和公差以及试验。

This Standard establishes specifications for wrought copper and wrought copper alloy, solder-joint, seamless fittings, designed for use with seamless copper tube conforming to ASTM B88 (water and general plumbing systems), B280 (air conditioning and refrigeration service), and B819 (medical gas systems), as well as fittings intended to be assembled with soldering materials conforming to ASTM B32, brazing materials conforming to AWS A5.8, or with tapered pipe thread conforming to ASME B1.20.1. This Standard is allied with ASME B16.18, which covers cast copper alloy pressure fittings. It provides requirements for fitting ends suitable for soldering. This Standard covers pressure-temperature ratings, abbreviations for end connections, size and method of designating openings of fittings, marking, material, dimensions and tolerances, and tests.
