Operation

The WellEnTech Hydraulic External Dimple System should be used with a hydraulic hand pump. Having selected a suitable System to suit the Coiled Tubing to be dimpled, it is then fitted to the Coiled Tubing and secured in place with a Socket Set Screws. The application of hydraulic pressure results in the forming of dimples onto the Coiled Tubing. The screws are backed off and the Dimple System rotated 90°.The dimpling process is repeated until all the dimples are formed. A pull test will confirm the Connector has been fitted correctly and a pressure test will verify that a seal has been maintained. The WellEnTech Hydraulic External Dimple System is supplied with a Slide Hammer and Threaded Sub to assist with the fitting and removal of the External Dimple Connector.
