1、文件名称：150Lb和300Lb常用法兰尺寸比较文件编号：B011，版本号：A第1页，共3页150Lb和300Lb常用法兰尺寸比较150Lb和300Lb常用法兰尺寸比较1 1 目的目的便于技术部及其他相关部门查阅。对比同规格不同标准法兰的大体差异。2 2 范围范围 CL150-CL300，DN15-DN350;整体钢制管法兰；RF/FF连接面法兰主要尺寸。3 3 参考文件参考文件 ASME B 16.5-2003，JIS B 2238，JIS B 2239，GB/T 9113.1-2000，JB/T 79.1-94,HG20596-97，HG 20618-97， DIN2543等。4 4 文件
2、内容文件内容 4.1 一般情况下，不同标准的压力等级或公称压力可以作如下对应。 表1 压力等级对应表 表1 压力等级对应表标准ANSIJISDINJB/T150Lb10K1.0/1.6MPa1.6MPa300Lb20K2.5/4.0MPa2.5/4.0MPa等级或公称压力600Lb40K6.3/10MPa6.3/10MPa6.3/10MPa900Lb63K16MPa16MPa16/26MPa16MPa1500LbGB/HG1.0/1.6/2.0MPa 2.5/4.0/5.0MPa注：1.由于温度等级和公称压力的温度基准不同，因此并没有严格的对应关系，此表仅作大致对应； 2.GB/HG/JB/J
3、T 中16MPa仅在DN50及以下口径时与ANSI1500Lb互换。 4.2 比较不同标准的法兰，有助于更准确地选择胚件或代用品。见以下表2-表7数据。由于在CL150、CL300两个磅级的RF、FF面法兰标注方式一致，且同口径同磅级的阀门结构长度不变，故在这两个磅级内的统计容易实现。除此外的型式请查阅相应标准。文件名称：150Lb和300Lb常用法兰尺寸比较GB/T9113.1-20001.0MPaD95105115140150165185200220250285340395445505C141616181820202022222424262626GB/T9113.1-20001.6MPaD
