TubeTrace HT is a pre-engineered electric traced tube
bundle for steam sample lines and impulse lines to pressure
transmitters. TubeTrace HT will provide water freeze protection
in ambient conditions down to -50°F (-45°C) with 25
mph (40 kph) wind conditions. HT will withstand continuous
steam exposure temperatures up to 750°F (399°C).
In the past, tubing subject to high temperature exposure
was heat traced with series resistance mineral insulated (MI)
heat trace. MI heaters are custom made to fit each application,
so long lead times are often required. TubeTrace HT
solves this with Thermon parallel resistance HPT heat trace
isolated from direct contact with high temperature tubing.
TubeTrace HT bundles are designed to withstand continuous
750°F (399°C) steam exposure temperature even when
power is applied to the heat trace during ambient conditions
of 40°F (5°C).
