Scope

This Standard establishes specifications for wrought copper and copper alloy seamless pressure fittings designed for use by soldering or brazing with seamless copper tube conforming to ASTM B88 (water and general plumbing systems), ASTM B280 (air onditioning and refrigeration service), and ASTM B819 (medical gas systems). Fittings made in accordance with this Standard are intended to be assembled with soldering materials conforming to ASTM B32, brazing materials conforming to AWS A5.8M/A5.8, or tapered pipe thread conforming to ASME B1.20.1. This Standard is allied with ASME B16.18, which covers cast copper alloy pressure fittings, and ASME B16.50, which covers wrought pressure fittings for brazing only. This Standard provides requirements for fitting ends of suitable depths to achieve required pressure ratingswhen joined by either soldering or brazing. This Standard covers the following: (a) pressure–temperature ratings (b) abbreviations for end connections (c) size and method of designating openings of fittings (d) marking (e) material (f) dimensions and tolerances (g) tests 本标准规定了锻造铜和铜合金无缝压力配件的规范，设计用于焊接或钎焊，无缝铜管符合ASTM B88（水和一般管道系统），ASTM B280（空气连通和制冷服务）和ASTM B819（医用气体系统）。根据本标准制造的配件应使用符合 ASTM B32 的焊接材料、符合 AWS A5.8M/A5.8 的钎焊材料或符合 ASME B1.20.1 的锥形管螺纹进行组装。 本标准与ASME B16.18（涵盖铸铜合金压力接头）和ASME B16.50（仅涵盖用于钎焊的锻造压力接头）结盟。本标准规定了通过焊接或钎焊连接时安装合适深度的端部以达到所需的压力额定值的要求。本标准涵盖以下内容： （a） 压力-温度额定值 （b） 端接的缩写 （c） 配件开口的尺寸和指定方法 （d） 标记 （e） 材料 （f） 尺寸和公差 （g） 试验
