API Casing and Tubing Couplings Price
Couplings are short lengths of pipe used to connect two joints of tubing or casing, which are painted with color codes on their external surface to indicate their grades. Couplings have internal threads (female thread form) machined to match the external threads (male thread form) of the long joints of casing & tubing. The two joints of casing & tubing are threaded into opposite ends of the casing & tubing coupling.
