In machinery, systems, or vehicle technology, exhaust pipelines are used in engine and hydraulic systems. They function, for example, as exhaust pipes, charge air pipes, cooling water pipes, or hydraulic pipes. Pipelines are manufactured in welded and bent forms, or a combination thereof.
In addition to mechanical stress and leak-tightness, exhaust pipelines must meet a variety of requirements to ensure that engine and hydraulic systems operate flawlessly.
With our many years of experience as a component and system supplier in pipe technology, we develop and produce custom pipelines for manufacturers of machinery, systems, and vehicle technology. We are able to produce the entire exhaust piping system according to your specifications as a ready-to-install solution. Our product range extends from turbo flanges to rain flaps and complete exhaust systems. NovaNox® exhaust pipelines are bent and welded from high-quality steel or stainless steel.
From simple to complex geometries, our modern manufacturing capabilities enable us to realise pipelines for every installation situation. NovaNox® exhaust pipelines are always custom-adapted to the installation possibilities. In this way, even particularly confined spaces are utilised effectively. With various surface treatments and pipe end finishes, we also supply ready-to-install pipelines.
To shape exhaust pipelines, NovaNox® uses various bending processes and techniques. For example, mandrel bending and roll bending are combined to reshape pipes multiple times. Reshaping is possible even if the pipes have been deformed previously. In mandrel bending, the pipes are pushed onto a mandrel and bent around the tool at a predetermined radius. To prevent the pipe from deflecting, it is stabilised with clamping jaws and sliding rails. In roll bending, however, deformation is achieved by adjustable rollers into which the pipe is clamped. This practice also refers to the process as rolling, pipe rolling, or profile rolling. This method allows for significantly tighter bending radii. All these processes are carried out on “cold” pipes.
“Cold” pipes or “cold bending” means that the pipes have been cooled after the manufacturing process and are then deformed. Deforming in a cold state enables a significantly wider spectrum of pipe and profile processing. Additionally, multiple transition bends can be executed on a single pipe. Another advantage is that the process is significantly more cost-effective and faster to implement. The only drawback is the limitation of processing from a diameter of 2 metres. Above this diameter, pipes must be processed in a high-temperature furnace.
The materials undergo thorough testing. This guarantees the quality of our products and 100% traceability.
The welding process is an extremely important process in pipe processing. It enables both simple and highly complex geometries. We use MIG, MAG, and TIG welding methods. These processes facilitate watertight welds and arc welds. For all mentioned methods, NovaNox® guarantees the deployment of qualified welders.
Further processes we undertake include laser cutting, milling, turning, riveting, grinding, and subsequent final assembly.
CNC control enables us to perform our various bending techniques and manufacture CNC-bent parts. This includes, for example, ellipses, ogival arches, scrolled arches, or 3D bent parts with changing radii and extremely precise transitions between bends and straight sections. With our CNC pipe bending machine, we can guarantee high quality standards. This is particularly important for products to be manufactured in series. The machine offers high repeatability for all bends. During the bending process, the achieved radius is continuously checked, thereby preventing errors or deviations.
NovaNox® double-walled exhaust pipelines are characterised by their extremely stable and vibration-resistant insulation. This ensures extreme heat resistance and durable thermal insulation. As a result, nearby sensitive components are optimally protected. Furthermore, thanks to custom manufacturing, an exhaust pipeline can be produced for any geometry. It can also be adapted to existing installation spaces and thus easily integrated. Moreover, it is watertight and resistant to fuel, oil, urea, and acids.
