Parflex HT - Heavy Steam Trace Bundles consist of a single process tube and tracer, a non-hygroscopic glass fiber thermal insulation that provides minimum heat loss and a tough, black, 105°C-rated, flame-resistant PVC (FR-PVC) jacket that protects the tubing against corrosive atmospheres, water, oils, acids, alkalies and most chemicals. Direct tracer to process tube contact produces higher process tube temperatures than the light trace product, making the HT - Heavy Steam Trace Tubing an optimal solution for applications that require elevated temperatures. Such applications include pressure transmission and analyzer sample lines carrying heavy oils or distillates, gases or vapors. For ordering information and specific product details, please review the literature listed under the Product Support tab.
