Couplings are produced from heavy walled steel that are approximately six inches to one foot in length.  This short length of pipe is used to connect two joints of casing/tubing. Coupling have internal threads (female threadform) machined to match the external threads (male threadform) of the long joints of casing/tubing. The two joints of pipe are threaded into opposite ends of the coupling.

Couplings are a very small percentage of the price of a string of pipe. However, frequently they are purchased on a very fast turnaround so the customer may ship an order of pipe to its customer. The end user is typically an oil company or a driller.

All couplings produced by LB Pipe meet API Specifications 5CT unless otherwise specified.  LB Pipe is required to be audited by the Licenses providers as well as annual audits from the American Petroleum Institute, (API).  This continues to ensure that we provide the highest quality product available in the industry
