API 5CT J55 casing pipe is used to support the well wall in the process of drilling and after completion, so as to carry out the drilling process and normal operation of the whole oil well after completion. API 5CT J55 casing pipe can be plain-end, threaded, or threaded and coupled. API 5CT J55 is similar to K55 except the Min. tensile strength is lower.

API 5CT J55 casing pipe specification:
Thread type: SC (Short round thread), LC (Long round thread), BC (Buttress thread)
Length: R1 (4.88-7.62m), R2 (7.62-10.36m), R3 (10.36-14.63m)

API 5CT J55 casing pipe is a low steel grade in oil-drilling, and its price is rather preferential among the casing pipe steel grades, so it enjoys wider applications. API 5CT J55 casing pipe is widely applied for shallow oil and gas extraction. It can be generally used in shallow wells, geothermal wells, and water wells.
