Depending on the application, exhaust gas lines are often operated under temperatures between 200° - 600°C. The material for the lines must be chosen based on the parameters: temperature, pressure, strength, and corrosion demands. The pipe or duct must be able to handle the linear expansions caused by these temperatures. For this, expansion joints and a combination of floating and fixed bearings are needed. Calculations for the piping network and a structural analysis are necessary for the planning and the drawings.
