API Downhole Casing and Tubing Pipe Couplings and Crossovers
Couplings are short lengths of pipe used to connect two joints of tubing or casing pipes, which are painted with color codes on their external surface to indicate their grades. We manufacture casing and tubing couplings for many years. All API sizes are available.
