Abstract
A polymer-lined fluid transmission line includes various structures, including a first polymer-lined pipe, a second polymer-lined pipe, and one or more sleeve retainers installed at a pipe junction between the polymer-lined pipes. Among other things, the sleeve retainers may include one or more protuberances to frictionally engage the polymer-lined pipes or a one or more portions that protrude into a space between the polymer-lined pipes to help retain and protect polymer sleeves.
