Parts production for energy industry

Energy technology

Casting components play an important role in the energy technology industry. They are notably used in applications where components are required that will withstand high temperatures and high levels of stress. When manufacturing our casting components, we work closely with our customers from the energy technology sector to develop a sophisticated and comprehensive approach, which is then efficiently put into action. This enables us to faithfully meet the very high requirements that are stipulated for components used in energy technology. Well-engineered and efficient bespoke casting components are essential to achieve high performance levels in gas and steam turbines used in the energy technology industry. We carry out a multitude of welding procedure tests when welding cast steel. We are always able to fulfill our customers’ specific requirements by carrying out additional welding procedure tests. We are also able to manufacture and weld silicon molybdenum alloyed and Ni-Resist cast iron in addition to the standard materials used in energy technology. Our highly qualified inspection team and our modern testing techniques ensure that the high standards demanded by the energy technology industry in terms of testing and documentation are always met. The Silbitz Group is regarded as a very reliable supplier and is valued highly by the large companies operating in the energy technology sector who have worked in close partnership with our company for many years.

Energy technology - the Silbitz group is your reliable partner

The Silbitz group develops overall concepts that meet the requirements together with energy technology customers in order to turn them into reality. Quality characteristics such as stability and long life-cycle are high priorities for energy technology. The repertoire of casting materials, that the Silbitz group can provide is varied. This includes, standard casting iron with lamellar or spheroidal graphite as well as casting iron with vermicular graphite, whose mechanical properties are to be classified between the first two materials above. Furthermore, in addition to classic cast steel and high-alloyed cast steel, they also offer austenitic cast iron (Ni-Resist) and the so-called “Austempered Ductile Iron" (ADI).

Casting parts in energy technology

Casting parts for energy technology, which are produced at the Silbitz, Košice and Zeitz facilities, weigh between approx. 10 kilograms to approx. 45 tons. Cast steel is manufactured at the main facility in Silbitz with weights ranging from approx. 250 kilograms to approx. 9 tons. We use different mould sections to produce casting parts for energy technology. This includes automatic moulding facilities, a mechanical hand moulding facility and classic hand moulding area. Different equipment is also used depending on the requirements and size of the component.

Casting parts requirements in energy technology

Energy technology is a science that includes the production, conversion, transport, storage and use of energy in all forms. Therefore, energy technology is becoming more and more essential and would not be possible without the use of casting parts. Achieving a high degree of efficiency has an important role, which is why casting parts are often an advantage. They are used where components are needed, which need to withstand high temperatures and pressures. If a high degree of efficiency is to be achieved in energy technology, well-engineered casting parts adapted to the situation are an absolute must for gas and steam turbines.

We offer individual and customised offers for energy technology

The Silbitz group has the possibility of providing welding procedure examinations for the welding of steel casting of any kind. Furthermore, there is the option of meeting customer-specific requirements through the acquisition of further welding procedure examinations. Therefore, in addition to all the classic energy technology materials, we are also able to produce SiMo materials (silicon-molybdenum) and Ni-Resist and weld them as well. Due to the highly qualified testing personnel and the latest testing equipment, the Silbitz groups meets the high test and documentation requirements of energy technology. Thus, the Silbitz group is a contact in terms of reliability and long-term partnership, for the most important companies of energy technology. We are your specialist for cast components that are to meet the highest quality, test and documentation requirements and if welding procedure examinations of any kind are needed.

We look forward to being able to make you an interesting offer.
