  注1:公差见表13.
  注2:使用条件和连接结构通常决定对短节的长度要求,因此,在订货时采购方必须规定是长型或短型短节。
A. 当短型翻边短节用于PN50和PN110的较大法兰以及大于等于PN150的大部分规格的法兰时;或当长型翻边短节用于PN260和PN420的较大法兰时,为了避免法兰可能影响焊接,可能需要增加接管的长度,长度增加量由制造商与采购方双方协商。
B. 当采用樺槽面和凹凸密封面时,必须增加搭接边的厚度。增加厚度应附加(不包括)在基本长度F上。
C. 这些尺寸应与GB/T9118.1-9118.2或ASME B15.5中的松套法兰的圆角半径相符合。
D. 该尺寸与ASME B16.5中表示的标准机加工面相符合。搭接边的背面应进行机加工,使其与安装表面一致,当采用环连接密封面时,使用ASME B16.5中给出的尺寸K。
