Abstract
An end termination assembly for a pipe liner includes a liner fitting and a clamping collar. The liner fitting has a nipple. The clamping collar can be disposed on the nipple to clamp the liner between the two components. A clamping surface of one or both of the nipple and clamping collar can be tapered to accommodate a range of liner wall thicknesses. The clamping collar can connect to the nipple without rotating. For example, a draw mechanism can draw the clamping collar along pipe liner to clamp the liner between collar and the nipple. The clamping collar and the nipple define an annular space in which a pipe liner can be clamped, and the radial thickness of the annular space is different at different positions of the collar.
