ABSTRACT:
An apparatus for connecting first and second flowline members for fluid flow therethrough and a method of utilizing same for effectuating such a repair, with the apparatus including a first housing member adapted to be mounted with the first flowline member and having a seal ring mounted therein for sealably engaging the butt end of a second flowline member for effecting a fluid-tight relation therebetween, a second housing member mounted for axial movement with respect to the first housing member and gripping means with the second housing member for moving radially inwardly into gripping engagement with the second flowline member upon axial movement of the second housing member toward the first housing member. In accomplishing the method of the present invention, a cutting of the flowline to remove the damaged portion must be effectuated and thereafter securing a first housing member of the apparatus to the replacement portion of the flowline, thereafter positioning the connector apparatus over the undamaged portion of the flowline such that the seal ring of the connector apparatus is in an abutting relation with the butt end surface of the undamaged portion of the flowline and thereafter moving the first and second housing members axially toward one another to effect an abutting, sealable relation between the butt end surface of the undamaged portion of the flowline and the seal ring and to grip the undamaged portion of the flowline with gripping means with the second housing member.
