What is an OCTG Connection?
The connection refers to the machined finish on the ends of each joint or piece of OCTG that allows the pieces to connect to one another to form a string of pipe in the well. OCTG pipe connections are leak-proof, strong, durable designs that fall into three general categories: API, Semi-Premium, and Premium.
API connections meet or exceed all American Petroleum Institute (API) specifications. Semi-Premium connections are similar to API but are engineered for enhanced torque. Premium connections provide performance beyond standard API connections and are engineered to produce a gas-tight metal-to-metal seal.
In terms of connection design, there are various types of connections. Thread manufacturers have engineered a number of proprietary threads within these types to best serve specific applications. The general types can be categorized as the following: Threaded and Coupled (T&C), Semi-Flush, and Flush.
A threaded and coupled connection uses a threaded coupling to join two threaded ends of pipe. A semi-flush connection has a slight upset and lacks a coupling so one threaded pin end fits into one threaded box end. A flush connection lacks an upset and a coupling where one threaded pin end fits flush into one threaded box end. This is desirable when clearances are limited downhole and there is nothing additional on the OD to accommodate a coupling or upset end.
OCTG can also be acquired with plain ends or without connections. Of course, it cannot be used downhole until it is threaded.
