A casing coupling is a short, threaded pipe used to connect two sections of casing in oil and gas wells. It has internal threads on both ends to join casing pipes of the same diameter, ensuring a continuous and secure casing string. Made from high-strength steel, couplings withstand extreme downhole conditions like pressure, corrosion, and mechanical stress.
