·本表列出的为承插焊管件各相同部分尺寸，不同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、承插孔径及流通孔尺寸表。
·当产品为异径时，流通孔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 norminal pipe size,size of center to the bottom of socket A issame to the straight fittings,

·本表并未限制使用较薄或较厚壁厚的管子和管件。实际采用的管子公称壁厚可小于或大于本表所示的管子公称壁厚。采用较薄管子时。其强度可支配额定值；采用较厚管子时（例如对机械强度而言），管件的强度支配额定值。
·This table is nkt intended to restrict the use of pipes and fittings of thinner or thicker wall.Pipe actually used may be thinner or thicker in nominal wall than that shown in Table. When thinner pipe is used,its strength may govern the rating.When thincker pipe is used(e.g,formechanical strength),the strength of the fitting governs the rating.
