Casing: Casing is a large diameter pipe that is assembled and inserted into a recently drilled section of a borehole and typically held into place with cement.
Casing Coupling: A short length of pipe used to connect two joints of casing. A casing coupling has internal threads machined to match the external threads of the long joints of casing. The two joints of casing are threaded into opposite ends of the casing coupling.
We provide our clients casing and coupling with required specification.
