Introduction
法蘭 (Flange)，又叫法蘭凸緣盤或突緣。法蘭是管道與管道之間相互連接的零件，用於管端之間的連接；也有 用在設備進出口上的法蘭，用於兩個設備之間的連接，如減速機法蘭。法蘭連接或法蘭接頭，是指由法蘭、墊 片及螺栓三者相互連接作為一組組合密封結構的可拆連接。管道法蘭係指管道裝置中配管用的法蘭，用在設備 上係指設備的進出口法蘭。法蘭上有孔眼，螺栓使兩法蘭緊連。法蘭間用襯墊密封。法蘭分螺紋連接法蘭、焊 接法蘭和卡夾法蘭。法蘭都是成對使用的，兩片法蘭盤之間加上密封墊片，然後用螺栓緊固。不同壓力的法蘭 厚度不同，它們使用的螺栓也不同。水泵和閥門，在和管道連接時，這些器材設備的局部，也製成相對應的法 蘭形狀，也稱為法蘭連接。凡是在兩個平面周邊使用螺栓連接同時封閉的連接零件，一般都稱為“ 法蘭 ”。 |

| 7 Welding Bevels | |||||
|
Butt welding ends having thicknesses (T) less than 3/16 inch
may have a slight chamfer or be square; thicknesses of 3/16 to 3/4 inch inclusive shall be beveled 371/2° and the root face (land) shall be 1/16 inch; thicknesses greater than 3/4 inch shall be beveled 371/2° with the thickness beyond 3/4 inch beveled 10°. |

| 8 Orifice Flange | |||||
|
For orifice flanges (not covered by ANSI B16.5) the usual
tolerance on the dimensions 15/16 inch from gasket surface to meter connection tap is ± 1/64 inch for sizes 3 inch and smaller, ± 1/32 inch for sizes 4 inch and larger; regular flange tolerances apply to all other dimensions expect bore tolerances which are 1/2 of 1 percent of nominal bore size. |
