Provided herein is a liner that can be loosely inserted in process pipe to form a lined pipe and to decrease the rate of heat transfer between process fluids flowing through the liner and the process pipe. The liner provided herein can reduce applied thermal loading on the outer pipe resulting from, for example, turbulent mixing between fluids having different temperatures (with or without stratification), circumferential thermal gradients, and/or longitudinal thermal gradients. An annulus between the process pipe and liner can be at least partially filled by process fluids, thereby creating a thermal buffer to further decrease the rate of heat transfer between the fluids and the process pipe.
A liner adapted for installation within a pipe, the liner sized to provide a gap between an outer wall of the liner and an inner wall of the pipe, the liner defining a channel adapted to convey a fluid therethrough and comprising a plurality of segments connected to one another by joints that permit movement of the segments relative to one another, wherein the liner is configured to provide fluid communication between the channel and the gap, and wherein fluid entering the gap forms a thermal buffer between the outer wall of the liner and the inner wall of the pipe, the fluid forming the thermal buffer extending substantially along the length of the pipe.
