Claim 15:
16. A terminated pipe liner to pipe connection comprising:
a host pipe system including a first host pipe and a second host pipe;
a pipe liner extending from the first host pipe;
a liner fitting having an axis, the liner fitting comprising a pipe coupling coupled to the second host pipe and a nipple received in an end portion of the pipe liner, the nipple extending away from the pipe coupling in a first axial direction, the nipple having a first end portion and a second end portion spaced apart from the first end portion in a second axial direction opposite the first axial direction, the nipple comprising an annular outer wall having an outer dimension and a length extending along the axis from the first end portion of the nipple to the second end of the nipple;
a clamping collar having a first end portion and a second end portion spaced apart from the first end portion of the clamping collar in the second axial direction, the clamping collar comprising an annular inner wall, the annular inner wall having an inner dimension and a length extending along the axis from the first end portion of the clamping collar to the second end portion of the clamping collar, the clamping collar being disposed about the nipple and clamping an end portion of the pipe liner between the annular inner wall and the annular outer wall of the nipple to fluidly couple the end portion termination assembly to the pipe liner;
at least one of the annular inner wall of the clamping collar and the annular outer wall of the nipple tapering radially inward as it extends lengthwise in the first axial direction such that the respective one of the inner dimension and the outer dimension gradually decreases from the second end portion to the first end portion of the respective one of the clamping collar and the nipple;
the clamping collar being connected to the nipple for nonrotational movement with respect to the nipple along the axis in the second axial direction for clamping the pipe liner onto the nipple;
the liner fitting and clamping collar being free of connection to the first host pipe except by the pipe liner.
