Application: gas, water and oil transportation in both oil and natural gas .
Steel grade: J55, K55, N80, L80, P110.
Packing: Barendles/crates/crate protection at the both sides of tubes or as per customers' requirements .
Painting: as requested.
API 5CT oil casing used in oil well drilling, which is mainly used for drilling and completion of the right wall of the support,
to ensure that the conduct and completion of the drilling process after the normal operation of the wells. Casing is to
maintain the wells run lifeline.
As different geological conditions, underground complex stress state, pulling, pressing, bending, torsional stress acting
on the combined effect of the tube, which the casing itself, the quality of the higher requirements. Once the casing
itself is damaged for some reason, could lead to the whole production wells, or even scrapped.
