Casing coupling vs tubing coupling
Casing couplings and tubing couplings are essential components in oil and gas well construction and production operations, playing critical roles in the assembly of continuous casing and tubing strings. Both types of couplings are designed to provide secure connections between pipe segments, enabling the extraction of hydrocarbons from subsurface reservoirs. While they share similarities in their threaded connections and sealing mechanisms, casing couplings and tubing couplings have distinct features, applications, and design considerations tailored to their specific functions in the well environment.
