 API 5CT P110 casing Tubing Specification

P110 API casing or tubing is a relatively common one in Oil drilling. Because of the low steel grade of P110, it is used for shallow oil and gas extraction. Due to its low price among other grades of steel, it enjoys broader applications. P110 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.

API 5CT P110 Casing Tubing Type of Casing:

a In case of dispute, laboratory Rockwell C hardness testing shall be used as the referee method.
b No hardness limits are specified, but the maximum variation is restricted as a manufacturing control in accordance with 7.8 and 7.9.
c For through-wall hardness tests of Grades L80 (all types), C90, T95 and C110, the requirements stated in HRC scale are for maximum mean hardness number.
