Parker LT Temptrace® Light Steam Trace Tubing
consists of single or multiple process tubes insulated
from a single tracer with non-hygroscopic glass fber
insulation and overall non-hygroscopic glass fber
insulation and black, 105°C rated, fame-resistant
PVC (FR PVC) jacket.
The LT Series Temptrace® is designed to utilize
saturated steam pressures to 230 PSIG (15.8 BAR)
and 400°F (204.4°C) without generating a process
tube temperature in excess of 200°F (93°C) or a
jacket surface temperature greater than 140°F (60°C)
at 80°F (26.6°C) ambient. Standard product has
a Maximum Temperature Rating (MTR*) of 400°F
(204.4°C). Higher temperature rated designs are
available. Consult Division for details.
*Maximum Temperature Rating is the maximum
allowable temperature of the tracing fuid.
Temperatures in excess of this may damage the
product or alter its performance.
Applications
The LT Temptrace® permits use of higher pressure
steam to heat trace instrument lines carrying
water, light oil, paraffn, paraffn-based fuids
and temperature-sensitive chemicals. Parker LT
Temptrace® is ideal for simple instrument line freeze
protection and viscosity maintenance applications.
Tubing
Type 122 DHP Seamless Copper and 316/316L
Welded Stainless Steel are standard. Additional
materials, wall thicknesses and seamless stainless
steel are available upon request. For Material
Specifcations of metal tubing, see Technical Data
section of the catalog. Consult Division for details.
LT— Light Steam Trace
Insulation
Patented (U.S. Pat. No. 4,285,369) air-spaced, cross
wrapped applied non-hygroscopic fberglass thermal
insulation for minimum heat loss. The insulated tracer
provides a more constant process tube temperature
over long tubing runs.
Jacket
The tough, black, 105°C rated, fame-resistant PVC
(FR PVC) jacket protects the tubing against corrosive
atmospheres, water, oils, acids, alkalies and most
chemicals. Additional jacket materials are available
upon request. For Material Specifcations of jackets,
see Technical Data section of the catalog. Consult
Division for additional details.
Testing
Each tube in every length of Parker Temptrace ®
is pressure tested prior to shipment to assure the
instrument engineer a high quality, reliable, trouble-
free product. For Testing Specifcations, see Technical
Data section of the catalog.
Accessories
Accessories are available for connecting multiple
lengths of steam trace bundles and sealing bundle
ends.
NOTE: It is absolutely necessary to seal the ends against
contamination from moisture and/or corrosive liquids. Parker
Hannifn cannot assume any liability for product damage caused by
moisture from unsealed ends.
Maximum Internal Exposure Temperature Rating up to 400°F (204°F)
