The wide range of applications in energy technology systems (stationary gas turbines, turbocompressors, pumps, etc.) requires a wide variety of material groups and state-of-the-art thermal processing processes. Listemann offers a wide range of materials knowledge paired with a portfolio of technical systems that is unparalleled in this combination.
The tasks in energy technology are very diverse, which is why Listemann has been adapting to a high degree of flexibility in terms of materials technology and machining options for many years.
Hot gas components, e.g. in stationary gas turbines, require a special sealing technology that can withstand the high-temperature conditions. For this purpose, so-called honeycomb segments are often used, on which the waterproofing partner can grind in. Listemann has many years of experience in soldering honeycomb segments or rings and supports you from the design to the series production of the products.
With these two processes in joining technology, Listemann offers new ways in the design of components. Do you want to combine two materials with different properties? Do you see opportunities in joining technology for simplifying production and thus perhaps also gaining an economic advantage? Talk to our team and you will be amazed at the possibilities of component design that are suddenly open to you.
Gas turbines or sometimes compressors can reach impressive sizes, depending on the required power. Of course, the individual components of these systems, i.e. the turbine or compressor parts, are also of the appropriate size. At Listemann, the smallest system has a usable space of 300 x 300 x 400 mm, while the largest has a usable diameter of 1500 mm and a usable height of 1800 mm with a capacity of up to 2000 kg. This means that we are also prepared for the series production of large components.
Turbo compressors are used for a wide variety of purposes. They are very often used in pipelines for pressure adjustment on long conveying distances. These turbocompressors contain radial impellers, most of which can be manufactured using integral production. In the case of complex or narrow channel geometry, they have to be manufactured in two parts and then brazed together again. The complex brazing technology with gold solder is a further specialization of Listemann. We process small impellers with a diameter of 300 mm through to impellers with a diameter of up to 700 mm and a weight of up to 250 kg.
Meeting company, national and international standards is not just a compulsory task for Listemann. Rather, it is our conviction that only secure business processes ensure our competitiveness and customer benefit.
