API 5CT J55 Casing

API 5CT J55 casing is a kind of large diameter pipes used for the drilling. API 5CT J55 casing diameter we offer ranges from 4.5 inch to 16 inch. API 5CT J55 casing advantages: API 5CT J55 casing has fixed the role of oil and gas oil casing or hole. API 5CT J55 casing is inserted into the hole and fixed with cement, in order to prevent the borehole and separated strata borehole collapse, and ensure the drilling mud circulating flow.

API 5CT J55 casing application: Oil casing pipe is mainly used in the drilling process and after the completion of borehole wall support, to ensure that the drilling process and after completion of the normal operation of the oil Wells. Main pipe will be well at the bottom of the oil and gas transmission to the ground.
