摘要
A coiled tubing connector having a body and a plurality of entry or transition sections connected to the body wherein the connector has a low cycle fatigue life of at least 30%, more preferably at least 50% of the coiled tubing. A preferred embodiment contains two shoulders that form an annular void, a plurality of centralizers about an exterior of the body, and/or a plurality of elastomer molds separating the centralizers. The connector is preferably longer than the connectors of the prior art and is a composite of fluoroplastics or aluminum alloys.
