Wieland Thermal Solutions with a focus on safety tubes and system efficiency at the ACHEMA 2015

At the ACHEMA in Frankfurt from 15 to 19 June 2015, Wieland Thermal Solutions will be presenting its GEWA-safe double wall safety tubes in hall 5.1 at stand D54.

The GEWA-safe tubes (practically a tube-in-tube solution) feature defined leakage paths between the inner and outer tube for the absolutely reliable separation of fluids, e.g. reactive, hazardous or explosive fluids, without the need for additional circulation (closed loop intermediate fluid). This ensures highest system availability, efficiency and safety, as damage to inner or outer tube is immediately recognisable and can be fixed as part of regularly scheduled maintenance. The excellent thermal contact of the two tubes results in outstanding heat transfer without additional heat transfer fluid. GEWA-safe tubes enable the manufacture of very compact heat exchangers, thus reducing material costs and fill levels. Depending on the desired application, the tubes are available with either smooth or profiled surface in copper, cupronickel and stainless steel. The safety tubes are used, for example, in the pre-heating of fuel gas for gas turbines, for the protection against environmentally harmful and toxic substances, for the isolation of heat transfer oil in transformer stations and for drinking water protection according to DIN EN 1717 in heat-pump systems. They are also used in so-called safety heat exchangers for highest standards regarding system safety in chemical processes, for example in the production of polysilicon.

In addition, Wieland Thermal Solutions will be presenting current solutions for system efficiency increase in the oil, gas and petrochemical industries as well as in the power generation industries. GEWA-PB tubes have in the meantime proved successful in ethylene and liquefied natural gas production. They enable 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 both the equipment as well as the overall plant design, for example regarding plot layout, liquid inventory, piping, racks and foundations.
