C90 API casing or tubing is a relatively common one in Oil drilling. Because of the low steel grade of C90, it is used for shallow oil and gas extraction. Due to its low price among other grades of steel, it enjoys broader applications. C90 API casing or tubing is widely used in the extraction of natural gas and coalbed methane, and can be commonly found in shallow wells, geothermal wells, and water wells.

NOTE See also Figures D.1, D.2, and D.3.
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.
