适用范围
This Standard establishes requirements for cast copper alloy solder joint pressure fittings designed for use by soldering or brazing with seamless copper water tube conforming to ASTM B88. Fittings made in accordance with this Standard are intended to be assembled with soldering materials conforming to ASTM B32, brazing materials conforming to AWS A5.8, or tapered pipe thread conforming to ASME B1.20.1. This Standard is allied to ASME B16.22 for wrought 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 depth to achieve required pressure ratings hen joined by either soldering or brazing. It establishes equirements for the following: (a) pressure–temperature ratings (b) abbreviations for end connections (c) sizes and method of designating openings of fittings (d) marking (e) material (f) dimensions and tolerances (g) tests 本标准规定了铸造铜合金焊点压力配件的要求,设计用于使用符合ASTM B88的无缝铜水管进行焊接或钎焊。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 A5.8 的钎焊材料或符合 ASME B1.20.1 的锥形管螺纹组装。 本标准与用于锻铜合金压力配件的ASME B16.22和仅用于钎焊的锻造压力配件的ASME B16.50保持一致。 本标准规定了合适深度的安装端部的要求,以达到所需的压力额定值 通过焊接或钎焊连接。它为以下各项建立了设备: (a) 压力-温度额定值 (b) 端接的缩写 (c) 指定配件开口的尺寸和方法 (d) 标记 (e) 材料 (f) 尺寸和公差 (g) 试验
