a Labels are for information and assistance in ordering.

b Nominal linear masses, threaded and coupled (col. 4) are shown for information only.

c The densities of martensitic chromium steels (L80 Types 9Cr and 13Cr) are less than those of carbon steels. The masses

shown are therefore not accurate for martensitic chromium steels. A mass correction factor of 0.989 may be used.

d Mass gain or loss due to end finishing. See 8.5.

e Drift diameter for most common bit size. This drift diameter shall be specified on the purchase agreement and marked on the

pipe. See 8.10 for drift requirements.
