Oil Casing Weight Calculation

Oil casing plays a vital role in the petroleum industry. Today, Union Steel Industry will introduce to you how to calculate the weight of oil and casing.

Oil Casing Weight Calculation Formula:

[(outer diameter-wall thickness)*wall thickness]*0.02466=kg/meter (weight per meter)

PS: Don’t forget to calculate the weight effect of the coupling.

Chemical Composition:

(1) According to the provisions of SY/T6194-96. The casing and its couplings are of the same steel grade. Sulfur content <0.045%, phosphorus content <0.045%;

(2) Take chemical analysis samples according to the provisions of GB/T222-84. Conduct chemical analysis according to relevant parts of GB223;

(3) The provisions of the American Petroleum Institute API SPEC 5CT 1988 1st Edition. Chemical analysis: Prepare samples according to the latest version of ASTME59, and conduct chemical analysis according to the latest version of ASTME350.

Physical Properties:

(1) According to the provisions of SY/T6194-96. Used for flattening test (GB246-97) tensile test (GB228-2010) and hydraulic test;

(2) Hydrostatic pressure test, flattening test, sulfide stress corrosion cracking test, hardness test (according to the latest version of ASTM E18 or E10), tensile test, transverse impact test (ASTMA370, ASTME23 and the latest version of relevant standards), Grain size determination (latest version of ASTME112 or other methods).

Package:

According to SY/T6194-96, household casing should be bundled with steel wire or steel tape. The exposed portion of each bushing and coupling thread shall have a protective ring threaded onto it to protect the threads.
