What is API 5CT Casing & Tubing?
Casing: Steel pipe placed in a wellbore to provide structural integrity, prevent contamination of freshwater zones, and withstand external pressures.
Tubing: Pipe used inside the casing to transport oil, gas, or other fluids from the reservoir to the surface.
Both are manufactured according to API 5CT standards to ensure consistency, performance, and safety in drilling and production operations.
