Notes:
Tubes of OD 2.063 in (52,4 mm), 5 inch (127 mm) and 5 1/2 inch (139,7 mm) upon agreement. Dimensions in brackets are from edition API 5CT – 2005.
Tolerance of dimensions:
OD < 4 1/2 inch = ± 0.79 mm ( ± 0.031 inch)
OD ≥ 4 1/2 inch = – 0,5 % +1,0 % OD
WT = – 12,5 % (+ limited by weight)
weight (1 tube) = –3,5 % +6,5 %
