NOTE: P=Plain-end,  S=Short round thread,  L=Long round thread,  B=Buttress thread.
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 diferent 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.
