本表列出的為承插焊管件各相同部分尺寸，不同部分標(biāo)準(zhǔn)規(guī)定的接管尺寸及承插孔徑d1、流通孔徑d2尺寸見承插焊管件的接管外徑、承插孔徑及流通孔及流通孔尺寸表。
當(dāng)產(chǎn)品為異徑時(shí)，流通孔徑d2的尺寸用異徑公稱通徑相對(duì)的d2尺寸、中心至承插孔底的尺寸A與同徑管件相同。
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. |
