GEWA-PB tubes have proved successful in ethylene and liquefied natural gas production, enabling a compact design of heat exchangers. The surface structure of the tube enhances the effect of nucleate boiling, thus intensifying the evaporation process. For the different requirements regarding thermal conductivity, mechanical properties and corrosion resistance in the oil and gas processing industries, Wieland Thermal Solutions will also be presenting at the Achema its portfolio of low-finned tubes in a wide range of materials. GEWA-K, GEWA-KS as well as Trufin S/T and Turbo-Chil tubes are manufactured in the materials carbon steel, stainless steel and titanium. They are mainly used in coolers, preheaters, condensers and evaporators to achieve savings in the overall design, for example regarding fill levels, piping, racks and foundations.
