a. Labels are for information and assistance in ordering.
b. Nominal linear masses (Column 4) are shown for information only.
c. The densities of martensitic chromium steels (L80 Types 9Cr and 13Cr) are different from carbon steels; The masses shown are therefore not accurate for martensitic chromium steels; A mass correction factor of 0.989 may be used.d. Buttress casing is available with regular, special clearance couplings or special clearance couplings with special bevel.
e. For casing with S, L, B connections, intermediate wall thicknesses are allowed in accordance with 5.2.3 and 8.2 and API 5B.
