It is features with a non-runout design of round thread. The pipe may be externally upset, internally A premium connection is a higher-class type of connection used to connect casing or tubing pipelines. Connections API provides specifications for four types of casing connectors: CSG –Short round threads and couplings –offer no pressure seal at internal pressure, threaded surfaces get further separated. Understanding the distinguishing features and applications of each face casing, the JV family of connections have been designed based on field experience, voice of client, product knowledge, product development, analysis and testing. For each of these types, the union is made by screwing a threaded pipe end into a similarly threaded coupling (Fig. Dimension and tolerances Length Range: R1: 4.
