1. A sleeve retainer for a polymer-lined pipe, the sleeve retainer comprising:
a tubular body comprising a first terminal end and a second terminal end and comprising an interior surface and an exterior surface defining an external diameter, wherein the tubular body comprises one or more protuberances for frictionally engaging an interior surface of the polymer-lined pipe, wherein the one or more protuberances define a protuberance outer diameter, such that the protuberance outer diameter is greater than the external diameter of the tubular body, and wherein the one or more protuberances include an O-ring seated in a groove;
the first terminal end of the tubular body configured to be inserted into the polymer-lined pipe; and
a flange protruding radially outward from the second terminal end, the flange comprising:
a flange base connected to the tubular body;
a flange distal edge spaced radially outward from the flange base;
a chamfered surface that transitions from a first position between the flange distal edge and the flange base to the distal edge of the flange.
