发明名称 Internal coiled tubing connector
摘要 The present invention generally relates to a connector for coiled tubing that resists torque developed by rotating downhole equipment. The connector couples to an inside diameter of the coiled tubing and can use a torque ring that rotationally locks the connector to the coiled tubing. Additionally, the connector can have a slot on an outside diameter thereof adapted to receive a weld bead on the inside diameter of the coiled tubing in order to rotationally lock the connector to the coiled tubing.
