Abstract
An isolated tracer includes an elongated tube, a layer of insulation covering the tube, and a layer of tape compressing the insulation to provide a desired conductance rate for the isolated tracer. The isolated tracer is made by passing a pipe concurrently through a funnel-shaped die with a layer of insulation and wrapping tape around the insulation after it leaves the die. The insulation is compressed to a desired amount to provide a desired conductance rate by adjusting tension on the tape as it is wound about the insulation covering the tube.
