Steel Casing Pipe Weight Calculation

Date:2022-02-25    keywords: casing pipe weight calculation
Steel casing pipe 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 SY/T6194-96 regulations. The casing and its coupling 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. Carry out chemical analysis according to the relevant part of GB223;
(3) Provisions of the American Petroleum Institute API SPEC 5CT 1988 1st Edition. Chemical analysis The samples were prepared according to the latest version of ASTME59, and the chemical analysis was carried out according to the latest version of ASTME350.


K55 casing pipe


Physical properties:
(1) According to SY/T6194-96 regulations. 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 (as specified in 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 (the latest version of ASTME112 or other methods).

Package:

According to SY/T6194-96, the domestic casing should be bundled with steel wire or steel belt. A protection ring shall be screwed on the exposed portion of each casing and coupling thread to protect the thread.
