a: Labels are for information and assistance in ordering. b: Nominal linear masses (col. 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 i s available with regualr, special clearance coupings or special clearance couplings with special bevel. |
