Performance Data


The HT-Heavy Steam Trace Tubing is designed to be used with steam pressures of 15 PSIG (1 BAR) to 230 PSIG (15.8 BAR) and maintain a process tube temperature of 200°F (93°C) at -40°F (-40°C) ambient to 355°F (179°C) at 80°F (26.6°C) ambient with product surface temperatures of less 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. Contact us for details.

*Maximum Temperature Rating is the maximum allowable temperature of the tracing fluid. Temperatures in excess of this may damage the product or alter its performance.


The HT-Heavy Steam trace Tubing is used with high temperature steam to heat trace instrument size lines when elevated temperatures are required. Such applications as pressure transmission and analyzer sample lines carrying heavy oils or distillates, gases or vapors are ideal service for the HT products. The direct tracer to process tube contact procedures higher process tube temperatures than the light trace product.


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 Specifications of metal tubing, please contact us.

Tubing Identification

When process tube and tracer tube are the same size and material, each individual tube is printed with tube number at two-inch intervals.


Air-spaced, cross wrapped applied non-hygroscopic fiberglass thermal insulation for minimum heat loss.


The tough, black, 105°C rated, flame-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 Specifications of jackets, please contact us.


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 Specifications, please contact us.


Accessories are available for conencting 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. Neither Parker Hannifin and/or Motion & Flow Control Products, Inc. can assume any liability for product damage caused by moisture from unsealed ends.
