TubeTrace HTX2
Tubing Bundles
TubeTrace HTX2 is a pre-engineered electric traced tube
bundle for steam sample lines and impulse lines to pressure
transmitters. TubeTrace HTX2 will provide water freeze protection
during -34°C 10 m/s wind conditions. HTX2 is suitable
for superheat steam service temperatures up to 595°C
for a duration of 2 minutes per cycle.
In the past, bundles subject to high temperature exposure
were heat traced with series resistance mineral insulated
(MI) heater cables that were custom made to length to fit
each application. Measurement errors rendered bundles
with MI heater cable unusable. TubeTrace HTX2 solves this
problem with Thermon parallel resistance HPT heater cable.
Bundles may be purchased in long rolls and “cut-to-length”
into smaller sections in the field for any application. This
minimizes waste and speeds up installation and engineering
time. HPT is contained within TubeTrace with a “double
layer thermal insulation system” that isolates it from extreme
heat exposure. TubeTrace HTX2 bundles can be controlled
with ambient sensing systems that turn heater cables
on when outdoor conditions approach freezing.
TubeTrace HTX2 bundles are suitable for intermittent superheat
steam service temperatures to 595°C even when
power is applied to the heater cable during ambient conditions
of 5°C, no wind.
