●本表列出的为承插焊管件各相同部分尺寸，不同部分标准规定的接管尺寸及承插孔径d1、流通孔径d2尺寸见承插焊管件的接管外径、承插孔径及流通孔及流通孔尺寸表。

●当产品为异径时，流通孔径d2的尺寸用异径公称通径相对的d2尺寸、中心至承插孔底的尺寸A与同径管件相同。
●The above list shows sizes of the same parts of SW fittings.The sizes of different codes pipes, socket diameter d1 and bore diameter d2 refer to the list of the pipe outside diameter, socket diameter and bore diameter of SW fittings.
●As to the reducing fittings, size of the bore diameter d2 applies to the relevant size d2 of the reducing 　nominal pipe size, size of center to the bottom of socket A is same to the straight fittings.
