A hanger assembly is carried in an inverted frusto- conical recess of the flow passage. The hanger assembly includes segmented slip and seal members moveable between outwardly expanded passive positions in which the slip and seal members do not interfere with full bore flow passage and inwardly contracted active positions in which gripping surfaces carried on slip members engage the coiled tubing to support the weight thereof, the weight of the tubing being transferred from the slip members to the sealing members. Slip activators carried by the tubing head are manipulatable externally of the tubing head to move the slip members from passive positions to active positions. Methods of utilizing the apparatus to install coiled tubing and equipment in a well are disclosed.
