a Labels are for information and assistance in ordering.
b Nominal linear masses, threaded and coupled (Column 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 shall 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 in the purchase agreement and marked on the pipe; See 8.10 for drift requirements.
f Based on 758 mPa minimum Yield strength or greater.
g Based on 379 mPa minimum yield strength.
