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).
