发明名称 Method of and apparatus for securing capillary tubing in a wellhead
摘要 A body having a bore therethrough for insertion of capillary tubing. A first means slidably coupled into the bore of the body frictionally restrains movement of the tubing by hydraulically engaging the periphery of the tubing with an elastomeric compressible sealing member. A second means slidably coupled into the bore of the body prevents movement of the tubing in the bore of the body by hydraulically actuating a plurality of slips to impart select engagement of the periphery of the tubing for its securement therein. A third means suspends the tubing in the bore of the body by manually engaging a plurality of suspension slips around the periphery of the tubing.
